Development

Git

• main is release branch and should remain stable at all times
• Create feature branches for your in-progress features and using the format <username>/my-feature (doesn't have to be your GitHub username, just use something identifiable and be consistent about it)
• Commit messages should follow the Conventional Commits specification as much as possible
• Squash commits into a single commit before merging into main
• Delete your branch after merging into main

Editor

• VS Code is the recommended IDE due to it's superb support for TypeScript
• Install the following extensions for VS Code, or find the equivalents for your IDE:
  • Prettier - Code formatter
  • TypeScript Importer
  • Tailwind CSS IntelliSense
  • ESLint
  • Prisma
  • Stylelint
  • Code Spell Checker
  • Optional: Tailwind Docs
• Use Workspace settings as source of truth for VS Code

Directory Structure

TBD

Front End

Next.js

• For most imports, use ~/ which is an alias for the apps/portal/src instead of relative paths.

React

• Props should be Readonly
• Props should be sorted alphabetically
• Props should be destructured in the component function declaration

Data Querying Library

React Query.

Form Library

TBD

Back End

Data Model: Prisma

We use Prisma, which is an ORM for JavaScript/TypeScript applications. Make sure you have the Prisma VS Code extension installed, which gives you autocompletion and formatting of the .prisma files.

• Naming
  • Namespace/Prefix your models per project (e.g. ResumeSomething, OfferSomething, QuestionSomething).
  • enum values should be written using UPPER_SNAKE_CASE.
  • Look around and see the existing schema fields and try to be consistent about field naming, even across projects.
• Fields
  • Use camelCase for fields in schema.prisma. If you see some snake_case fields in Account, that's because of the requirements of NextAuth.js, and they are exceptions.
  • Use cuid() for ids, don't use autoincrement(). We don't want to reveal how many rows there are in a table.

Prisma Studio

In case you want to have an admin view of your database, run yarn prisma studio which will run an admin web app on http://localhost:5555.

Server API calls: tRPC

• userIds for creator fields should always come from the session, not from a parameter.
• Prisma doesn’t have ACL (access control list), so we need to manually implement permissioning in tRPC routing code.

Database

Set up your own PostgreSQL database and update the DATABASE_URL field within the .env file.

Run prisma migrate dev if it's your first time.
