 - `npm run build:worker`: Runs the [@opennextjs/cloudflare](https://www.npmjs.com/package/@opennextjs/cloudflare) adapter. This first builds your app by running the `build` script in your `package.json` (Next.js apps use `next build` by default), and then transforms the build output to a format that you can run locally using [Wrangler](https://developers.cloudflare.com/workers/wrangler/), and deploy to Cloudflare. The build command used by OpenNext can be overridden with the `buildCommand` option in your OpenNext config.
 - `npm run dev:worker`: Takes the output generated by `build:worker` and runs it locally in [workerd](https://github.com/cloudflare/workerd), the open-source Workers Runtime, allowing you to run the app locally in the same environment that it will run in production. If you instead run `next dev`, your app will run in Node.js, which is a different JavaScript runtime from the Workers runtime, with differences in behavior and APIs.
-- `npm run preview:worker`: Runs `build:worker` and then `dev:worker`, allowing you to quickly preview your app running locally in the Workers runtime, via a single command.
+- `npm run preview`: Runs `build:worker` and then `dev:worker`, allowing you to quickly preview your app running locally in the Workers runtime, via a single command.
 - `npm run deploy`: Builds your app, and then deploys it to Cloudflare
+- `cf-typegen`: Generates a `cloudflare-env.d.ts` file at the root of your project containing [the types for the `env`](https://developers.cloudflare.com/workers/wrangler/commands/#types).
