Wanneer je npm install uitvoert, leest npm het package.json-bestand in de hoofdmap van je project, dat de afhankelijkheden voor het project vermeldt. Vervolgens downloadt en installeert het die afhankelijkheden in de node_modules map in het project. In de terminal van Visual Studio Code zijn er een aantal commando's voor gebruikt om het NPM init te initialiseren, installeren NPM install en testen met NPM start. In de map Node_Modules hebben wij Nodemon geactiveerd om bij iedere aanpassing die wij hebben opgeslagen in de server te laten verversen. Hiervoor gebruiken wij het commando NPM install Nodemon. + +Express is een webframework voor Node.js dat wordt gebruikt voor het bouwen van webapplicaties en API's. EJS is een templating engine die wordt gebruikt voor het genereren van dynamische HTML-pagina's op basis van gegevens vanuit een server. In combinatie worden Express en EJS vaak gebruikt voor het bouwen van dynamische websites + +## .gitignore en .env +Voor dit project hebben wij .env gebruikt omdat wij met echte data gingen werken. Om Api key te beschermen hebben wij een .env mapje aangemaakt en daar API key aangekoppeld. Api key van Oba is hierdoor beschermd. Door .env in de gitignore mapje te plaatsen gaat de API key niet mee naar github en is dit niet zichtbaar online. + +## Progressive Enhancement +Om ervoor te zorgen dat iedereen toegang heeft tot het project, hebben wij de methode "progressive enhancement" gebruikt. Hierbij hebben we eerst de inhoud van de webpagina opgebouwd met behulp van HTML, geïntegreerd in EJS. Vervolgens heb ik functionaliteit toegevoegd door middel met de GET en POST-methode. Voor CSS hebben we diverse CSS-stijlen gebruikt om de website te stijlen in de huisstijl van OBA. + + +## 💾 Bronnen +- MDN documents +- Pagespeed insights +- Lighthouse +- Can i use +- DOC (instructions) -## Bronnen -## Licentie +## 📠 Licentie This project is licensed under the terms of the [MIT license](./LICENSE). diff --git a/index.js b/index.js new file mode 100644 index 00000000..115ab1d0 --- /dev/null +++ b/index.js @@ -0,0 +1,283 @@ +// Importeert basis modules uit npm +import express from "express";

If you want to read in quiet mode, set the value to `4 * os.cpus().length` (4 is default size of [thread pool work scheduling](http://docs.libuv.org/en/v1.x/threadpool.html#thread-pool-work-scheduling)). + +### deepFilter + +* Type: [`DeepFilterFunction`](./src/settings.ts) +* Default: `undefined` + +A function that indicates whether the directory will be read deep or not. + +```ts +// Skip all directories that starts with `node_modules` +const filter: DeepFilterFunction = (entry) => !entry.path.startsWith('node_modules'); +``` + +### entryFilter + +* Type: [`EntryFilterFunction`](./src/settings.ts) +* Default: `undefined` + +A function that indicates whether the entry will be included to results or not. + +```ts +// Exclude all `.js` files from results +const filter: EntryFilterFunction = (entry) => !entry.name.endsWith('.js'); +``` + +### errorFilter + +* Type: [`ErrorFilterFunction`](./src/settings.ts) +* Default: `undefined` + +A function that allows you to skip errors that occur when reading directories. + +For example, you can skip `ENOENT` errors if required: + +```ts +// Skip all ENOENT errors +const filter: ErrorFilterFunction = (error) => error.code == 'ENOENT'; +``` + +### stats + +* Type: `boolean` +* Default: `false` + +Adds an instance of `fs.Stats` class to the [`Entry`](#entry). + +> :book: Always use `fs.readdir` with additional `fs.lstat/fs.stat` calls to determine the entry type. + +### followSymbolicLinks + +* Type: `boolean` +* Default: `false` + +Follow symbolic links or not. Call `fs.stat` on symbolic link if `true`. + +### `throwErrorOnBrokenSymbolicLink` + +* Type: `boolean` +* Default: `true` + +Throw an error when symbolic link is broken if `true` or safely return `lstat` call if `false`. + +### `pathSegmentSeparator` + +* Type: `string` +* Default: `path.sep` + +By default, this package uses the correct path separator for your OS (`\` on Windows, `/` on Unix-like systems). But you can set this option to any separator character(s) that you want to use instead. + +### `fs` + +* Type: `FileSystemAdapter` +* Default: A default FS methods + +By default, the built-in Node.js module (`fs`) is used to work with the file system. You can replace any method with your own. + +```ts +interface FileSystemAdapter { + lstat: typeof fs.lstat; + stat: typeof fs.stat; + lstatSync: typeof fs.lstatSync; + statSync: typeof fs.statSync; + readdir: typeof fs.readdir; + readdirSync: typeof fs.readdirSync; +} + +const settings = new fsWalk.Settings({ + fs: { lstat: fakeLstat } +}); +``` + +## Changelog + +See the [Releases section of our

(#1572) +- We are now making heavy use of ES2015 features, this means we have dropped out-of-the-box support for Node 4 and earlier, and many old versions of browsers. (#1541, #1553) +- In `queue`, `priorityQueue`, `cargo` and `cargoQueue`, the "event"-style methods, like `q.drain` and `q.saturated` are now methods that register a callback, rather than properties you assign a callback to. They are now of the form `q.drain(callback)`. If you do not pass a callback a Promise will be returned for the next occurrence of the event, making them `await`-able, e.g. `await q.drain()`. (#1586, #1641) +- Calling `callback(false)` will cancel an async method, preventing further iteration and callback calls. This is useful for preventing memory leaks when you break out of an async flow by calling an outer callback. (#1064, #1542) +- `during` and `doDuring` have been removed, and instead `whilst`, `doWhilst`, `until` and `doUntil` now have asynchronous `test` functions.

Special thanks to [**@hargasinski**](https://github.com/hargasinski) for his work converting our old docs to `jsdoc` format and implementing the new website. Also huge ups to [**@ivanseidel**](https://github.com/ivanseidel) for designing our new logo. It was a long process for both of these tasks, but I think these changes turned out extraordinary well. + +The biggest feature is modularization. You can now `require("async/series")` to only require the `series` function. Every Async library function is available this way. You still can `require("async")` to require the entire library, like you could do before. + +We also provide Async as a collection of ES2015 modules. You can now `import {each} from 'async-es'` or `import waterfall from 'async-es/waterfall'`. If you are using only a few Async functions, and are using a ES bundler such as Rollup, this can significantly lower your build size. + +Major thanks to [**@Kikobeats**](github.com/Kikobeats), [**@aearly**](github.com/aearly) and [**@megawac**](github.com/megawac) for doing the majority of the modularization work, as well as [**@jdalton**](github.com/jdalton) and [**@Rich-Harris**](github.com/Rich-Harris) for advisory work on the general modularization strategy. + +Another one of the general themes of the 2.0 release is standardization of what an "async" function is. We are now more strictly following the node-style continuation passing style. That is, an async function is a function that: + +1. Takes a variable number of arguments +2. The last argument is always a callback +3. The callback can accept any number of arguments +4. The first argument passed to the callback will be treated as an error result, if the argument is truthy +5. Any number of result arguments can be passed after the "error" argument +6. The callback is called once and exactly once, either on the same tick or later tick of the JavaScript event loop. + +There were several cases where Async accepted some functions that did not strictly have these properties, most notably `auto`, `every`, `some`, `filter`, `reject` and `detect`. + +Another theme is performance. We have eliminated internal deferrals in all cases where they make sense. For example, in `waterfall` and `auto`, there was a `setImmediate` between each task -- these deferrals have been removed. A `setImmediate` call can add up to 1ms of delay. This might not seem like a lot, but it can add up if you are using many Async functions in the course of processing a HTTP request, for example. Nearly all asynchronous functions that do I/O already have some sort of deferral built in, so the extra deferral is unnecessary. The trade-off of this change is removing our built-in stack-overflow defense. Many synchronous callback calls in series can quickly overflow the JS call stack. If you do have a function that is sometimes synchronous (calling its callback on the same tick), and are running into stack overflows, wrap it with `async.ensureAsync()`. + +Another big performance win has been re-implementing `queue`, `cargo`, and `priorityQueue` with [doubly linked lists](https://en.wikipedia.org/wiki/Doubly_linked_list) instead of arrays. This has lead to queues being an order of [magnitude faster on large sets of tasks](https://github.com/caolan/async/pull/1205). + +## New Features + +- Async is now modularized. Individual functions can be `require()`d from the main package. (`require('async/auto')`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996)) +- Async is also available as a collection of ES2015 modules in the new `async-es` package. (`import {forEachSeries} from 'async-es'`) ([#984](https://github.com/caolan/async/issues/984), [#996](https://github.com/caolan/async/issues/996)) +- Added `race`, analogous to `Promise.race()`. It will run an array of async tasks in parallel and will call its callback with the result of the first task to respond. ([#568](https://github.com/caolan/async/issues/568), [#1038](https://github.com/caolan/async/issues/1038)) +- Collection methods now accept ES2015 iterators. Maps, Sets, and anything that implements the iterator spec can now be passed directly to `each`, `map`, `parallel`, etc.. ([#579](https://github.com/caolan/async/issues/579), [#839](https://github.com/caolan/async/issues/839), [#1074](https://github.com/caolan/async/issues/1074)) +- Added `mapValues`, for mapping over the properties of an object and returning an object with the same keys. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177)) +- Added `timeout`, a wrapper for an async function that will make the task time-out after the specified time. ([#1007](https://github.com/caolan/async/issues/1007), [#1027](https://github.com/caolan/async/issues/1027)) +- Added `reflect` and `reflectAll`, analagous to [`Promise.reflect()`](http://bluebirdjs.com/docs/api/reflect.html), a wrapper for async tasks that always succeeds, by gathering results and errors into an object. ([#942](https://github.com/caolan/async/issues/942), [#1012](https://github.com/caolan/async/issues/1012), [#1095](https://github.com/caolan/async/issues/1095)) +- `constant` supports dynamic arguments -- it will now always use its last argument as the callback. ([#1016](https://github.com/caolan/async/issues/1016), [#1052](https://github.com/caolan/async/issues/1052)) +- `setImmediate` and `nextTick` now support arguments to partially apply to the deferred function, like the node-native versions do. ([#940](https://github.com/caolan/async/issues/940), [#1053](https://github.com/caolan/async/issues/1053)) +- `auto` now supports resolving cyclic dependencies using [Kahn's algorithm](https://en.wikipedia.org/wiki/Topological_sorting#Kahn.27s_algorithm) ([#1140](https://github.com/caolan/async/issues/1140)). +- Added `autoInject`, a relative of `auto` that automatically spreads a task's dependencies as arguments to the task function.

([#635](https://github.com/caolan/async/issues/635), [#637](https://github.com/caolan/async/issues/637)) +- Added `retryable`, a relative of `retry` that wraps an async function, making it retry when called. ([#1058](https://github.com/caolan/async/issues/1058)) +- `retry` now supports specifying a function that determines the next time interval, useful for exponential backoff, logging and other retry strategies. ([#1161](https://github.com/caolan/async/issues/1161)) +- `retry` will now pass all of the arguments the task function was resolved with to the callback ([#1231](https://github.com/caolan/async/issues/1231)). +- Added `q.unsaturated` -- callback called when a `queue`'s number of running workers falls below a threshold. ([#868](https://github.com/caolan/async/issues/868), [#1030](https://github.com/caolan/async/issues/1030), [#1033](https://github.com/caolan/async/issues/1033), [#1034](https://github.com/caolan/async/issues/1034)) +- Added `q.error` -- a callback called whenever a `queue` task calls its callback with an error. ([#1170](https://github.com/caolan/async/issues/1170)) +- `applyEach` and `applyEachSeries` now pass results to the final callback. ([#1088](https://github.com/caolan/async/issues/1088)) + +## Breaking changes + +- Calling a callback more than once is considered an error, and an error will be thrown. This had an explicit breaking change in `waterfall`. If you were relying on this behavior, you should more accurately represent your control flow as an event emitter or stream. ([#814](https://github.com/caolan/async/issues/814), [#815](https://github.com/caolan/async/issues/815), [#1048](https://github.com/caolan/async/issues/1048), [#1050](https://github.com/caolan/async/issues/1050)) +- `auto` task functions now always take the callback as the last argument. If a task has dependencies, the `results` object will be passed as the first argument. To migrate old task functions, wrap them with [`_.flip`](https://lodash.com/docs#flip) ([#1036](https://github.com/caolan/async/issues/1036), [#1042](https://github.com/caolan/async/issues/1042)) +- Internal `setImmediate` calls have been refactored away. This may make existing flows vulnerable to stack overflows if you use many synchronous functions in series. Use `ensureAsync` to work around this. ([#696](https://github.com/caolan/async/issues/696), [#704](https://github.com/caolan/async/issues/704), [#1049](https://github.com/caolan/async/issues/1049), [#1050](https://github.com/caolan/async/issues/1050)) +- `map` used to return an object when iterating over an object. `map` now always returns an array, like in other libraries. The previous object behavior has been split out into `mapValues`. ([#1157](https://github.com/caolan/async/issues/1157), [#1177](https://github.com/caolan/async/issues/1177)) +- `filter`, `reject`, `some`, `every`, `detect` and their families like `{METHOD}Series` and `{METHOD}Limit` now expect an error as the first callback argument, rather than just a simple boolean. Pass `null` as the first argument, or use `fs.access` instead of `fs.exists`. ([#118](https://github.com/caolan/async/issues/118), [#774](https://github.com/caolan/async/issues/774), [#1028](https://github.com/caolan/async/issues/1028), [#1041](https://github.com/caolan/async/issues/1041)) +- `{METHOD}` and `{METHOD}Series` are now implemented in terms of `{METHOD}Limit`. This is a major internal simplification, and is not expected to cause many problems, but it does subtly affect how functions execute internally. ([#778](https://github.com/caolan/async/issues/778), [#847](https://github.com/caolan/async/issues/847)) +- `retry`'s callback is now optional. Previously, omitting the callback would partially apply the function, meaning it could be passed directly as a task to `series` or `auto`. The partially applied "control-flow" behavior has been separated out into `retryable`. ([#1054](https://github.com/caolan/async/issues/1054), [#1058](https://github.com/caolan/async/issues/1058)) +- The test function for `whilst`, `until`, and `during` used to be passed non-error args from the iteratee function's callback, but this led to weirdness where the first call of the test function would be passed no args. We have made it so the test function is never passed extra arguments, and only the `doWhilst`, `doUntil`, and `doDuring` functions pass iteratee callback arguments to the test function ([#1217](https://github.com/caolan/async/issues/1217), [#1224](https://github.com/caolan/async/issues/1224)) +- The `q.tasks` array has been renamed `q._tasks` and is now implemented as a doubly linked list (DLL). Any code that used to interact with this array will need to be updated to either use the provided helpers or support DLLs ([#1205](https://github.com/caolan/async/issues/1205)). +- The timing of the `q.saturated()` callback in a `queue` has been modified to better reflect when tasks pushed to the queue will start queueing. ([#724](https://github.com/caolan/async/issues/724), [#1078](https://github.com/caolan/async/issues/1078)) +- Removed `iterator` method in favour of [ES2015 iterator protocol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_Generators ) which natively supports arrays ([#1237](https://github.com/caolan/async/issues/1237)) +- Dropped support for Component, Jam, SPM, and Volo ([#1175](https://github.com/caolan/async/issues/1175), #[#176](https://github.com/caolan/async/issues/176)) + +## Bug Fixes + +- Improved handling of no dependency cases in `auto` & `autoInject` ([#1147](https://github.com/caolan/async/issues/1147)). +- Fixed a bug where the callback generated by `asyncify` with `Promises` could resolve twice ([#1197](https://github.com/caolan/async/issues/1197)). +- Fixed several documented optional callbacks not actually being optional ([#1223](https://github.com/caolan/async/issues/1223)). + +## Other + +- Added `someSeries` and `everySeries` for symmetry, as well as a complete set of `any`/`anyLimit`/`anySeries` and `all`/`/allLmit`/`allSeries` aliases. +- Added `find` as an alias for `detect.

browser). + * If you are using `async` functions through a transpiler (e.g. Babel), you + * must still wrap the function with [asyncify]{@link module:Utils.asyncify}, + * because the `async function`

The callback should be called with a + * Error as its first argument to signal that an error occurred. + * Otherwise, if no error occurred, it should be called with `null` as the first + * argument, and any additional `result` arguments that may apply, to signal + * successful completion. + * The callback must be called exactly once, ideally on a later tick of the + * JavaScript event loop. + * + * This type of function is also referred to as a "Node-style async function", + * or a "continuation passing-style function" (CPS). Most of the methods of this + * library are themselves CPS/Node-style async functions, or functions that + * return CPS/Node-style async functions. + * + * Wherever we accept a Node-style async function, we also directly accept an + * [ES2017 `async` function]{@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function}. + * In this case, the `async` function will not be passed a final callback + * argument, and any thrown error will be used as the `err` argument of the + * implicit callback, and the return value will be used as the `result` value. + * (i.e. a `rejected` of the returned Promise becomes the `err` callback + * argument, and a `resolved` value becomes the `result`.) + * + * Note, due to JavaScript limitations, we can only detect native `async` + * functions and not transpilied implementations. + * Your environment must have `async`/`await` support for this to work. + * (e.g. Node > v7.6, or a recent version of a modern browser). + * If you are using `async` functions through a transpiler (e.g. Babel), you + * must still wrap the function with [asyncify]{@link module:Utils.asyncify}, + * because the `async function` will be compiled to an ordinary function that + * returns a promise. + * + * @typedef {Function} AsyncFunction + * @static + */ + +/** + * Async is a utility module which provides straight-forward, powerful functions + * for working with asynchronous JavaScript.

Fresh cache entries are served directly from cache and stale cache entries are revalidated with `If-None-Match`/`If-Modified-Since` headers. You can read more about the underlying cache behaviour in the `cacheable-request` [documentation](https://github.com/lukechilds/cacheable-request). + +You can use the JavaScript `Map` type as an in memory cache: + +```js +const got = require('got'); +const map = new Map(); + +(async () => { + let response = await got('sindresorhus.com', {cache: map}); + console.log(response.fromCache); + //=> false + + response = await got('sindresorhus.com', {cache: map}); + console.log(response.fromCache); + //=> true +})(); +``` + +Got uses [Keyv](https://github.com/lukechilds/keyv) internally to support a wide range of storage adapters. For something more scalable you could use an [official Keyv storage adapter](https://github.com/lukechilds/keyv#official-storage-adapters): + +``` +$ npm install @keyv/redis +``` + +```js +const got = require('got'); +const KeyvRedis = require('@keyv/redis'); + +const redis = new KeyvRedis('redis://user:pass@localhost:6379'); + +got('sindresorhus.com', {cache: redis}); +``` + +Got supports anything that follows the Map API, so it's easy to write your own storage adapter or use a third-party solution. + +For example, the following are all valid storage adapters: + +```js +const storageAdapter = new Map(); +// or +const storageAdapter = require('./my-storage-adapter'); +// or +const QuickLRU = require('quick-lru'); +const storageAdapter = new QuickLRU({maxSize: 1000}); + +got('sindresorhus.com', {cache: storageAdapter}); +``` + +View the [Keyv docs](https://github.com/lukechilds/keyv) for more information on how to use storage adapters. + + +## Proxies + +You can use the [`tunnel`](https://github.com/koichik/node-tunnel) module with the `agent` option to work with proxies: + +```js +const got = require('got'); +const tunnel = require('tunnel'); + +got('sindresorhus.com', { + agent: tunnel.httpOverHttp({ + proxy: { + host: 'localhost' + } + }) +}); +``` + +If you require different agents for different protocols, you can pass a map of agents to the `agent` option. This is necessary because a request to one protocol might redirect to another. In such a scenario, `got` will switch over to the right protocol agent for you. + +```js +const got = require('got'); +const HttpAgent = require('agentkeepalive'); +const HttpsAgent = HttpAgent.HttpsAgent; + +got('sindresorhus.com', { + agent: { + http: new HttpAgent(), + https: new HttpsAgent() + } +}); +``` + + +## Cookies + +You can use the [`cookie`](https://github.com/jshttp/cookie) module to include cookies in a request: + +```js +const got = require('got'); +const cookie = require('cookie'); + +got('google.com', { + headers: { + cookie: cookie.serialize('foo', 'bar') + } +}); +``` + + +## Form data + +You can use the [`form-data`](https://github.com/form-data/form-data) module to create POST request with form data: + +```js +const fs = require('fs'); +const got = require('got'); +const FormData = require('form-data'); +const form = new FormData(); + +form.append('my_file', fs.createReadStream('/foo/bar.jpg')); + +got.post('google.com', { + body: form +}); +``` + + +## OAuth + +You can use the [`oauth-1.0a`](https://github.com/ddo/oauth-1.0a) module to create a signed OAuth request: + +```js +const got = require('got'); +const crypto = require('crypto'); +const OAuth = require('oauth-1.0a'); + +const oauth = OAuth({ + consumer: { + key: process.env.CONSUMER_KEY, + secret: process.env.CONSUMER_SECRET + }, + signature_method: 'HMAC-SHA1', + hash_function: (baseString, key) => crypto.createHmac('sha1', key).update(baseString).digest('base64') +}); + +const token = { + key: process.env.ACCESS_TOKEN, + secret: process.env.ACCESS_TOKEN_SECRET +}; + +const url = 'https://api.twitter.com/1.1/statuses/home_timeline.json'; + +got(url, { + headers: oauth.toHeader(oauth.authorize({url, method: 'GET'}, token)), + json: true +}); +``` + + +## Unix Domain Sockets + +Requests can also be sent via [unix domain sockets](http://serverfault.com/questions/124517/whats-the-difference-between-unix-socket-and-tcp-ip-socket). Use the following URL scheme: `PROTOCOL://unix:SOCKET:PATH`. + +- `PROTOCOL` - `http` or `https` *(optional)* +- `SOCKET` - absolute path to a unix domain socket, e.g. `/var/run/docker.sock` +- `PATH` - request path, e.g. `/v2/keys` + +```js +got('http://unix:/var/run/docker.sock:/containers/json'); + +// or without protocol (http by default) +got('unix:/var/run/docker.sock:/containers/json'); +``` + +## AWS + +Requests to AWS services need to have their headers signed. This can be accomplished by using the [`aws4`](https://www.npmjs.com/package/aws4) package. This is an example for querying an ["Elasticsearch Service"](https://aws.amazon.com/elasticsearch-service/) host with a signed request. + +```js +const url = require('url'); +const AWS = require('aws-sdk'); +const aws4 = require('aws4'); +const got = require('got'); +const config = require('./config'); + +// Reads keys from the environment or `~/.aws/credentials`. Could be a plain object. +const awsConfig = new AWS.Config({ region: config.region }); + +function request(uri, options) { + const awsOpts = { + region: awsConfig.region, + headers: { + accept: 'application/json', + 'content-type': 'application/json' + }, + method: 'GET', + json: true + }; + + // We need to parse the URL before passing it to `got` so `aws4` can sign the request + const opts = Object.assign(url.parse(uri), awsOpts, options); + aws4.sign(opts, awsConfig.credentials); + + return got(opts); +} + +request(`https://${config.host}/production/users/1`); + +request(`https://${config.host}/production/`, { + // All usual `got` options +}); +``` + + +## Testing + +You can test your requests by using the [`nock`](https://github.com/node-nock/nock) module to mock an endpoint: + +```js +const got = require('got'); +const nock = require('nock'); + +nock('https://sindresorhus.com') + .get('/') + .reply(200, 'Hello world!'); + +(async () => { + const response = await got('sindresorhus.com'); + console.log(response.body); + //=> 'Hello world!' +})(); +``` + +If you need real integration tests you can use [`create-test-server`](https://github.com/lukechilds/create-test-server): + +```js +const got = require('got'); +const createTestServer = require('create-test-server'); + +(async () => { + const server = await createTestServer(); + server.get('/', 'Hello world!'); + + const response = await got(server.url); + console.log(response.body); + //=> 'Hello world!' + + await server.close(); +})(); +``` + + +## Tips + +### User Agent + +It's a good idea to set the `'user-agent'` header so the provider can more easily see how their resource is used. By default, it's the URL to this repo. + +```js +const got = require('got'); +const pkg = require('./package.json'); + +got('sindresorhus.com', { + headers: { + 'user-agent': `my-module/${pkg.version} (https://github.com/username/my-module)` + } +}); +``` + +### 304 Responses + +Bear in mind, if you send an `if-modified-since` header and receive a `304 Not Modified` response, the body will be empty.

This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream. + +Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object. + +`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with: + +```js +var bl = require('bl') +var myinstance = bl() + +// equivalent to: + +var BufferList = require('bl') +var myinstance = new BufferList() +``` + +-------------------------------------------------------- + +### bl.length +Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list. + +-------------------------------------------------------- + +### bl.append(Buffer | Buffer array | BufferList | BufferList array | String) +`append(buffer)` adds an additional buffer or BufferList to the internal list. `this` is returned so it can be chained. + +-------------------------------------------------------- + +### bl.get(index) +`get()` will return the byte at the specified index. + +-------------------------------------------------------- + +### bl.slice([ start, [ end ] ]) +`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively. + +If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer. + +-------------------------------------------------------- + +### bl.shallowSlice([ start, [ end ] ]) +`shallowSlice()` returns a new `BufferList` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively. + +No copies will be performed. All buffers in the result share memory with the original list. + +-------------------------------------------------------- + +### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ]) +`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively. + +-------------------------------------------------------- + +### bl.duplicate() +`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example: + +```js +var bl = new BufferList() + +bl.append('hello') +bl.append(' world') +bl.append('\n') + +bl.duplicate().pipe(process.stdout, { end: false }) + +console.log(bl.toString()) +``` + +-------------------------------------------------------- + +### bl.consume(bytes) +`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers—initial offsets will be calculated accordingly in order to give you a consistent view of the data. + +-------------------------------------------------------- + +### bl.toString([encoding, [ start, [ end ]]]) +`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information. + +-------------------------------------------------------- + +### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8() + +All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently. + +See the [Buffer](http://nodejs.org/docs/latest/api/buffer.html) documentation for how these work. + +-------------------------------------------------------- + +### Streams +**bl** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream.

If removal or resignation of a WG member, or a change of +employment by a WG member, creates a situation where more than 1/3 of +the WG membership shares an employer, then the situation must be +immediately remedied by the resignation or removal of one or more WG +members affiliated with the over-represented employer(s). + +### WG Meetings + +The WG meets occasionally on a Google Hangout On Air.

Each meeting should be +published to YouTube. + +Items are added to the WG agenda that are considered contentious or +are modifications of governance, contribution policy, WG membership, +or release process. + +The intention of the agenda is not to approve or review all patches; +that should happen continuously on GitHub and be handled by the larger +group of Collaborators. + +Any community member or contributor can ask that something be added to +the next meeting's agenda by logging a GitHub Issue. Any Collaborator, +WG member or the moderator can add the item to the agenda by adding +the ***WG-agenda*** tag to the issue. + +Prior to each WG meeting the moderator will share the Agenda with +members of the WG. WG members can add any items they like to the +agenda at the beginning of each meeting. The moderator and the WG +cannot veto or remove items. + +The WG may invite persons or representatives from certain projects to +participate in a non-voting capacity. + +The moderator is responsible for summarizing the discussion of each +agenda item and sends it as a pull request after the meeting. + +### Consensus Seeking Process + +The WG follows a +[Consensus +Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making) +decision-making model. + +When an agenda item has appeared to reach a consensus the moderator +will ask "Does anyone object?" as a final call for dissent from the +consensus. + +If an agenda item cannot reach a consensus a WG member can call for +either a closing vote or a vote to table the issue to the next +meeting. The call for a vote must be seconded by a majority of the WG +or else the discussion will continue. Simple majority wins. + +Note that changes to WG membership require a majority consensus.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +'use strict'; + +module.exports = Transform; + +var Duplex = require('./_stream_duplex'); + +/**/ +var util = Object.create(require('core-util-is')); +util.inherits = require('inherits'); +/**/ + +util.inherits(Transform, Duplex); + +function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; + + var cb = ts.writecb; + + if (!cb) { + return this.emit('error', new Error('write callback called multiple times')); + } + + ts.writechunk = null; + ts.writecb = null; + + if (data != null) // single equals check for both `null` and `undefined` + this.push(data); + + cb(er); + + var rs = this._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + this._read(rs.highWaterMark); + } +} + +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + + Duplex.call(this, options); + + this._transformState = { + afterTransform: afterTransform.bind(this), + needTransform: false, + transforming: false, + writecb: null, + writechunk: null, + writeencoding: null + }; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + + if (options) { + if (typeof options.transform === 'function') this._transform = options.transform; + + if (typeof options.flush === 'function') this._flush = options.flush; + } + + // When the writable side finishes, then flush out anything remaining. + this.on('prefinish', prefinish); +} + +function prefinish() { + var _this = this; + + if (typeof this._flush === 'function') { + this._flush(function (er, data) { + done(_this, er, data); + }); + } else { + done(this, null, null); + } +} + +Transform.prototype.push = function (chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

This allows applications to avoid the garbage collection overhead of +creating many individually allocated Buffers. This approach improves both +performance and memory usage by eliminating the need to track and cleanup as +many `Persistent` objects. + +However, in the case where a developer may need to retain a small chunk of +memory from a pool for an indeterminate amount of time, it may be appropriate +to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then +copy out the relevant bits. + +```js +// need to keep around a few small chunks of memory +const store = []; + +socket.on('readable', () => { + const data = socket.read(); + // allocate for retained data + const sb = Buffer.allocUnsafeSlow(10); + // copy the data into the new allocation + data.copy(sb, 0, 0, 10); + store.push(sb); +}); +``` + +Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after* +a developer has observed undue memory retention in their applications. + +A `TypeError` will be thrown if `size` is not a number. + +### All the Rest + +The rest of the `Buffer` API is exactly the same as in node.js. +[See the docs](https://nodejs.org/api/buffer.html). + + +## Related links + +- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660) +- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4) + +## Why is `Buffer` unsafe? + +Today, the node.js `Buffer` constructor is overloaded to handle many different argument +types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.), +`ArrayBuffer`, and also `Number`. + +The API is optimized for convenience: you can throw any type at it, and it will try to do +what you want. + +Because the Buffer constructor is so powerful, you often see code like this: + +```js +// Convert UTF-8 strings to hex +function toHex (str) { + return new Buffer(str).toString('hex') +} +``` + +***But what happens if `toHex` is called with a `Number` argument?*** + +### Remote Memory Disclosure + +If an attacker can make your program call the `Buffer` constructor with a `Number` +argument, then they can make it allocate uninitialized memory from the node.js process. +This could potentially disclose TLS private keys, user data, or database passwords. + +When the `Buffer` constructor is passed a `Number` argument, it returns an +**UNINITIALIZED** block of memory of the specified `size`.

It's surprisingly common to forget to check the type of your variables in a +dynamically-typed language like JavaScript. + +Usually the consequences of assuming the wrong type is that your program crashes with an +uncaught exception. But the failure mode for forgetting to check the type of arguments to +the `Buffer` constructor is more catastrophic. + +Here's an example of a vulnerable service that takes a JSON payload and converts it to +hex: + +```js +// Take a JSON payload {str: "some string"} and convert it to hex +var server = http.createServer(function (req, res) { + var data = '' + req.setEncoding('utf8') + req.on('data', function (chunk) { + data += chunk + }) + req.on('end', function () { + var body = JSON.parse(data) + res.end(new Buffer(body.str).toString('hex')) + }) +}) + +server.listen(8080) +``` + +In this example, an http client just has to send: + +```json +{ + "str": 1000 +} +``` + +and it will get back 1,000 bytes of uninitialized memory from the server. + +This is a very serious bug. It's similar in severity to the +[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process +memory by remote attackers. + + +### Which real-world packages were vulnerable? + +#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) + +[Mathias Buus](https://github.com/mafintosh) and I +([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, +[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow +anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get +them to reveal 20 bytes at a time of uninitialized memory from the node.js process. + +Here's +[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) +that fixed it. We released a new fixed version, created a +[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all +vulnerable versions on npm so users will get a warning to upgrade to a newer version. + +#### [`ws`](https://www.npmjs.com/package/ws) + +That got us wondering if there were other vulnerable packages. Sure enough, within a short +period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the +most popular WebSocket implementation in node.js. + +If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as +expected, then uninitialized server memory would be disclosed to the remote peer. + +These were the vulnerable methods: + +```js +socket.send(number) +socket.ping(number) +socket.pong(number) +``` + +Here's a vulnerable socket server with some echo functionality: + +```js +server.on('connection', function (socket) { + socket.on('message', function (message) { + message = JSON.parse(message) + if (message.type === 'echo') { + socket.send(message.data) // send back the user's message + } + }) +}) +``` + +`socket.send(number)` called on the server, will disclose server memory. + +Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue +was fixed, with a more detailed explanation. Props to +[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the +[Node Security Project disclosure](https://nodesecurity.io/advisories/67). + + +### What's the solution? + +It's important that node.js offers a fast way to get memory otherwise performance-critical +applications would needlessly get a lot slower. + +But we need a better way to *signal our intent* as programmers. **When we want +uninitialized memory, we should request it explicitly.** + +Sensitive functionality should not be packed into a developer-friendly API that loosely +accepts many different types. This type of API encourages the lazy practice of passing +variables in without checking the type very carefully. + +#### A new API: `Buffer.allocUnsafe(number)` + +The functionality of creating buffers with uninitialized memory should be part of another +API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that +frequently gets user input of all sorts of different types passed into it. + +```js +var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### How do we fix node.js core? + +We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as +`semver-major`) which defends against one case: + +```js +var str = 16 +new Buffer(str, 'utf8') +``` + +In this situation, it's implied that the programmer intended the first argument to be a +string, since they passed an encoding as a second argument. Today, node.js will allocate +uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not +what the programmer intended. + +But this is only a partial solution, since if the programmer does `new Buffer(variable)` +(without an `encoding` parameter) there's no way to know what they intended. If `variable` +is sometimes a number, then uninitialized memory will sometimes be returned. + +### What's the real long-term fix? + +We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when +we need uninitialized memory. But that would break 1000s of packages. + +~~We believe the best solution is to:~~ + +~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ + +~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ + +#### Update + +We now support adding three new APIs: + +- `Buffer.from(value)` - convert from any type to a buffer +- `Buffer.alloc(size)` - create a zero-filled buffer +- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size + +This solves the core problem that affected `ws` and `bittorrent-dht` which is +`Buffer(variable)` getting tricked into taking a number argument. + +This way, existing code continues working and the impact on the npm ecosystem will be +minimal. Over time, npm maintainers can migrate performance-critical code to use +`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. + + +### Conclusion + +We think there's a serious design issue with the `Buffer` API as it exists today. It +promotes insecure software by putting high-risk functionality into a convenient API +with friendly "developer ergonomics". + +This wasn't merely a theoretical exercise because we found the issue in some of the +most popular npm packages. + +Fortunately, there's an easy fix that can be applied today.

+under the `req.body` property. + +**Note** As `req.body`'s shape is based on user-controlled input, all +properties and values in this object are untrusted and should be validated +before trusting. For example, `req.body.foo.toString()` may fail in multiple +ways, for example the `foo` property may not be there or may not be a string, +and `toString` may not be a function and instead a string or other user input. + +[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/). + +_This does not handle multipart bodies_, due to their complex and typically +large nature.

All +middlewares will populate the `req.body` property with the parsed body when +the `Content-Type` request header matches the `type` option, or an empty +object (`{}`) if there was no body to parse, the `Content-Type` was not matched, +or an error occurred. + +The various errors returned by this module are described in the +[errors section](#errors). + +### bodyParser.json([options]) + +Returns middleware that only parses `json` and only looks at requests where +the `Content-Type` header matches the `type` option. This parser accepts any +Unicode encoding of the body and supports automatic inflation of `gzip` and +`deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). + +#### Options + +The `json` function takes an optional `options` object that may contain any of +the following keys: + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### reviver + +The `reviver` option is passed directly to `JSON.parse` as the second +argument. You can find more information on this argument +[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter). + +##### strict + +When set to `true`, will only accept arrays and objects; when `false` will +accept anything `JSON.parse` accepts. Defaults to `true`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not a +function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `json`), a mime type (like `application/json`), or +a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type` +option is called as `fn(req)` and the request is parsed if it returns a truthy +value. Defaults to `application/json`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.raw([options]) + +Returns middleware that parses all bodies as a `Buffer` and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser supports automatic inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This will be a `Buffer` object +of the body. + +#### Options + +The `raw` function takes an optional `options` object that may contain any of +the following keys: + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. +If not a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this +can be an extension name (like `bin`), a mime type (like +`application/octet-stream`), or a mime type with a wildcard (like `*/*` or +`application/*`). If a function, the `type` option is called as `fn(req)` +and the request is parsed if it returns a truthy value. Defaults to +`application/octet-stream`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.text([options]) + +Returns middleware that parses all bodies as a string and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser supports automatic inflation of `gzip` and `deflate` encodings. + +A new `body` string containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This will be a string of the +body. + +#### Options + +The `text` function takes an optional `options` object that may contain any of +the following keys: + +##### defaultCharset + +Specify the default character set for the text content if the charset is not +specified in the `Content-Type` header of the request. Defaults to `utf-8`. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not +a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `txt`), a mime type (like `text/plain`), or a mime +type with a wildcard (like `*/*` or `text/*`). If a function, the `type` +option is called as `fn(req)` and the request is parsed if it returns a +truthy value. Defaults to `text/plain`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.urlencoded([options]) + +Returns middleware that only parses `urlencoded` bodies and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser accepts only UTF-8 encoding of the body and supports automatic +inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This object will contain +key-value pairs, where the value can be a string or array (when `extended` is +`false`), or any type (when `extended` is `true`). + +#### Options + +The `urlencoded` function takes an optional `options` object that may contain +any of the following keys: + +##### extended + +The `extended` option allows to choose between parsing the URL-encoded data +with the `querystring` library (when `false`) or the `qs` library (when +`true`). The "extended" syntax allows for rich objects and arrays to be +encoded into the URL-encoded format, allowing for a JSON-like experience +with URL-encoded. For more information, please +[see the qs library](https://www.npmjs.org/package/qs#readme). + +Defaults to `true`, but using the default has been deprecated. Please +research into the difference between `qs` and `querystring` and choose the +appropriate setting. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### parameterLimit + +The `parameterLimit` option controls the maximum number of parameters that +are allowed in the URL-encoded data. If a request contains more parameters +than this value, a 413 will be returned to the client. Defaults to `1000`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not +a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `urlencoded`), a mime type (like +`application/x-www-form-urlencoded`), or a mime type with a wildcard (like +`*/x-www-form-urlencoded`). If a function, the `type` option is called as +`fn(req)` and the request is parsed if it returns a truthy value. Defaults +to `application/x-www-form-urlencoded`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +## Errors + +The middlewares provided by this module create errors using the +[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors +will typically have a `status`/`statusCode` property that contains the suggested +HTTP response code, an `expose` property to determine if the `message` property +should be displayed to the client, a `type` property to determine the type of +error without matching against the `message`, and a `body` property containing +the read body, if available. + +The following are the common errors created, though any error can come through +for various reasons. + +### content encoding unsupported + +This error will occur when the request had a `Content-Encoding` header that +contained an encoding but the "inflation" option was set to `false`. The +`status` property is set to `415`, the `type` property is set to +`'encoding.unsupported'`, and the `charset` property will be set to the +encoding that is unsupported. + +### entity parse failed + +This error will occur when the request contained an entity that could not be +parsed by the middleware. The `status` property is set to `400`, the `type` +property is set to `'entity.parse.failed'`, and the `body` property is set to +the entity value that failed parsing. + +### entity verify failed + +This error will occur when the request contained an entity that could not be +failed verification by the defined `verify` option. The `status` property is +set to `403`, the `type` property is set to `'entity.verify.failed'`, and the +`body` property is set to the entity value that failed verification. + +### request aborted + +This error will occur when the request is aborted by the client before reading +the body has finished. The `received` property will be set to the number of +bytes received before the request was aborted and the `expected` property is +set to the number of expected bytes. The `status` property is set to `400` +and `type` property is set to `'request.aborted'`. + +### request entity too large + +This error will occur when the request body's size is larger than the "limit" +option. The `limit` property will be set to the byte limit and the `length` +property will be set to the request body's length. The `status` property is +set to `413` and the `type` property is set to `'entity.too.large'`. + +### request size did not match content length + +This error will occur when the request's length did not match the length from +the `Content-Length` header. This typically occurs when the request is malformed, +typically when the `Content-Length` header was calculated based on characters +instead of bytes. The `status` property is set to `400` and the `type` property +is set to `'request.size.invalid'`. + +### stream encoding should not be set + +This error will occur when something called the `req.setEncoding` method prior +to this middleware. This module operates directly on bytes only and you cannot +call `req.setEncoding` when using this module. The `status` property is set to +`500` and the `type` property is set to `'stream.encoding.set'`. + +### stream is not readable + +This error will occur when the request is no longer readable when this middleware +attempts to read it. This typically means something other than a middleware from +this module read the request body already and the middleware was also configured to +read the same request. The `status` property is set to `500` and the `type` +property is set to `'stream.not.readable'`. + +### too many parameters + +This error will occur when the content of the request exceeds the configured +`parameterLimit` for the `urlencoded` parser. The `status` property is set to +`413` and the `type` property is set to `'parameters.too.many'`. + +### unsupported charset "BOGUS" + +This error will occur when the request had a charset parameter in the +`Content-Type` header, but the `iconv-lite` module does not support it OR the +parser does not support it. The charset is contained in the message as well +as in the `charset` property. The `status` property is set to `415`, the +`type` property is set to `'charset.unsupported'`, and the `charset` property +is set to the charset that is unsupported. + +### unsupported content encoding "bogus" + +This error will occur when the request had a `Content-Encoding` header that +contained an unsupported encoding. The encoding is contained in the message +as well as in the `encoding` property. The `status` property is set to `415`, +the `type` property is set to `'encoding.unsupported'`, and the `encoding` +property is set to the encoding that is unsupported. + +## Examples + +### Express/Connect top-level generic + +This example demonstrates adding a generic JSON and URL-encoded parser as a +top-level middleware, which will parse the bodies of all incoming requests. +This is the simplest setup. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse application/x-www-form-urlencoded +app.use(bodyParser.urlencoded({ extended: false })) + +// parse application/json +app.use(bodyParser.json()) + +app.use(function (req, res) { + res.setHeader('Content-Type', 'text/plain') + res.write('you posted:\n') + res.end(JSON.stringify(req.body, null, 2)) +}) +``` + +### Express route-specific + +This example demonstrates adding body parsers specifically to the routes that +need them. In general, this is the most recommended way to use body-parser with +Express. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// create application/json parser +var jsonParser = bodyParser.json() + +// create application/x-www-form-urlencoded parser +var urlencodedParser = bodyParser.urlencoded({ extended: false }) + +// POST /login gets urlencoded bodies +app.post('/login', urlencodedParser, function (req, res) { + res.send('welcome, ' + req.body.username) +}) + +// POST /api/users gets JSON bodies +app.post('/api/users', jsonParser, function (req, res) { + // create user in req.body +}) +``` + +### Change accepted type for parsers + +All the parsers accept a `type` option which allows you to change the +`Content-Type` that the middleware will parse. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse various different custom JSON types as JSON +app.use(bodyParser.json({ type: 'application/*+json' })) + +// parse some custom thing into a Buffer +app.use(bodyParser.raw({ type: 'application/vnd.custom-type' })) + +// parse an HTML body into a string +app.use(bodyParser.text({ type: 'text/html' })) +``` + +## License + +[MIT](LICENSE) + +[ci-image]: https://badgen.net/github/checks/expressjs/body-parser/master?label=ci +[ci-url]: https://github.com/expressjs/body-parser/actions/workflows/ci.yml +[coveralls-image]: https://badgen.net/coveralls/c/github/expressjs/body-parser/master +[coveralls-url]: https://coveralls.io/r/expressjs/body-parser?branch=master +[node-version-image]: https://badgen.net/npm/node/body-parser +[node-version-url]: https://nodejs.org/en/download +[npm-downloads-image]: https://badgen.net/npm/dm/body-parser +[npm-url]: https://npmjs.org/package/body-parser +[npm-version-image]: https://badgen.net/npm/v/body-parser diff --git a/node_modules/body-parser/SECURITY.md b/node_modules/body-parser/SECURITY.md new file mode 100644 index 00000000..9694d429 --- /dev/null +++ b/node_modules/body-parser/SECURITY.md @@ -0,0 +1,25 @@ +# Security Policies and Procedures + +## Reporting a Bug + +The Express team and community take all security bugs seriously.

This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. + +Example _app.js_: + +```js +var debug = require('debug')('http') + , http = require('http') + , name = 'My App'; + +// fake app + +debug('booting %s', name); + +http.createServer(function(req, res){ + debug(req.method + ' ' + req.url); + res.end('hello\n'); +}).listen(3000, function(){ + debug('listening'); +}); + +// fake worker of some kind + +require('./worker'); +``` + +Example _worker.js_: + +```js +var debug = require('debug')('worker'); + +setInterval(function(){ + debug('doing some work'); +}, 1000); +``` + + The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples: + + ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png) + + ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png) + +#### Windows note + + On Windows the environment variable is set using the `set` command. + + ```cmd + set DEBUG=*,-not_this + ``` + + Note that PowerShell uses different syntax to set environment variables. + + ```cmd + $env:DEBUG = "*,-not_this" + ``` + +Then, run the program to be debugged as usual. + +## Millisecond diff + + When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png) + + When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below: + + ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png) + +## Conventions + + If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". + +## Wildcards + + The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + + You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". + +## Environment Variables + + When running through Node.js, you can set a few environment variables that will + change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + + __Note:__ The environment variables beginning with `DEBUG_` end up being + converted into an Options object that gets used with `%o`/`%O` formatters. + See the Node.js documentation for + [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) + for the complete list. + +## Formatters + + + Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + +### Custom formatters + + You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + +## Browser support + You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), + or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), + if you don't want to build it yourself. + + Debug's enable state is currently persisted by `localStorage`. + Consider the situation shown below where you have `worker:a` and `worker:b`, + and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +#### Web Inspector Colors + + Colors are also enabled on "Web Inspectors" that understand the `%c` formatting + option. These are WebKit web inspectors, Firefox ([since version + 31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) + and the Firebug plugin for Firefox (any version). + + Colored output looks something like: + + ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png) + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example _stdout.js_: + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + +## Backers + +Support us with a monthly donation and help us continue our activities.

In other words: + +* [brace expansion](#brace-expansion) is for generating new lists +* [brace matching](#brace-matching) is for filtering existing lists + +
+More about brace expansion (click to expand) + +There are two main types of brace expansion: + +1. **lists**: which are defined using comma-separated values inside curly braces: `{a,b,c}` +2. **sequences**: which are defined using a starting value and an ending value, separated by two dots: `a{1..3}b`. Optionally, a third argument may be passed to define a "step" or increment to use: `a{1..100..10}b`. These are also sometimes referred to as "ranges". + +Here are some example brace patterns to illustrate how they work: + +**Sets** + +``` +{a,b,c} => a b c +{a,b,c}{1,2} => a1 a2 b1 b2 c1 c2 +``` + +**Sequences** + +``` +{1..9} => 1 2 3 4 5 6 7 8 9 +{4..-4} => 4 3 2 1 0 -1 -2 -3 -4 +{1..20..3} => 1 4 7 10 13 16 19 +{a..j} => a b c d e f g h i j +{j..a} => j i h g f e d c b a +{a..z..3} => a d g j m p s v y +``` + +**Combination** + +Sets and sequences can be mixed together or used along with any other strings. + +``` +{a,b,c}{1..3} => a1 a2 a3 b1 b2 b3 c1 c2 c3 +foo/{a,b,c}/bar => foo/a/bar foo/b/bar foo/c/bar +``` + +The fact that braces can be "expanded" from relatively simple patterns makes them ideal for quickly generating test fixtures, file paths, and similar use cases. + +## Brace matching + +In addition to _expansion_, brace patterns are also useful for performing regular-expression-like matching. + +For example, the pattern `foo/{1..3}/bar` would match any of following strings: + +``` +foo/1/bar +foo/2/bar +foo/3/bar +``` + +But not: + +``` +baz/1/qux +baz/2/qux +baz/3/qux +``` + +Braces can also be combined with [glob patterns](https://github.com/jonschlinkert/micromatch) to perform more advanced wildcard matching. For example, the pattern `*/{1..3}/*` would match any of following strings: + +``` +foo/1/bar +foo/2/bar +foo/3/bar +baz/1/qux +baz/2/qux +baz/3/qux +``` + +## Brace matching pitfalls + +Although brace patterns offer a user-friendly way of matching ranges or sets of strings, there are also some major disadvantages and potential risks you should be aware of. + +### tldr + +**"brace bombs"** + +* brace expansion can eat up a huge amount of processing resources +* as brace patterns increase _linearly in size_, the system resources required to expand the pattern increase exponentially +* users can accidentally (or intentially) exhaust your system's resources resulting in the equivalent of a DoS attack (bonus: no programming knowledge is required!) + +For a more detailed explanation with examples, see the [geometric complexity](#geometric-complexity) section. + +### The solution + +Jump to the [performance section](#performance) to see how Braces solves this problem in comparison to other libraries. + +### Geometric complexity + +At minimum, brace patterns with sets limited to two elements have quadradic or `O(n^2)` complexity. But the complexity of the algorithm increases exponentially as the number of sets, _and elements per set_, increases, which is `O(n^c)`. + +For example, the following sets demonstrate quadratic (`O(n^2)`) complexity: + +``` +{1,2}{3,4} => (2X2) => 13 14 23 24 +{1,2}{3,4}{5,6} => (2X2X2) => 135 136 145 146 235 236 245 246 +``` + +But add an element to a set, and we get a n-fold Cartesian product with `O(n^c)` complexity: + +``` +{1,2,3}{4,5,6}{7,8,9} => (3X3X3) => 147 148 149 157 158 159 167 168 169 247 248 + 249 257 258 259 267 268 269 347 348 349 357 + 358 359 367 368 369 +``` + +Now, imagine how this complexity grows given that each element is a n-tuple: + +``` +{1..100}{1..100} => (100X100) => 10,000 elements (38.4 kB) +{1..100}{1..100}{1..100} => (100X100X100) => 1,000,000 elements (5.76 MB) +``` + +Although these examples are clearly contrived, they demonstrate how brace patterns can quickly grow out of control. + +**More information** + +Interested in learning more about brace expansion? + +* [linuxjournal/bash-brace-expansion](http://www.linuxjournal.com/content/bash-brace-expansion) +* [rosettacode/Brace_expansion](https://rosettacode.org/wiki/Brace_expansion) +* [cartesian product](https://en.wikipedia.org/wiki/Cartesian_product) + +
+ +## Performance + +Braces is not only screaming fast, it's also more accurate the other brace expansion libraries. + +### Better algorithms + +Fortunately there is a solution to the ["brace bomb" problem](#brace-matching-pitfalls): _don't expand brace patterns into an array when they're used for matching_. + +Instead, convert the pattern into an optimized regular expression.
