Project Overview

Describe your project here. What does it do? Who uses it?

Tech Stack

• Language: TypeScript / Node.js
• Framework: (e.g., Next.js, Express, NestJS)
• Database: (e.g., PostgreSQL with Prisma)
• Testing: (e.g., Jest + Playwright)
• CI/CD: (e.g., GitHub Actions)

Repository Layout

src/
  components/    # React components
  lib/           # Shared utilities
  api/           # API route handlers
  types/         # TypeScript type definitions
tests/
  unit/          # Unit tests
  e2e/           # End-to-end tests
docs/            # Documentation

Code Conventions

• Use const over let wherever possible
• Prefer functional components over class components
• Always add JSDoc comments to exported functions
• Keep functions under 50 lines; extract helpers when needed
• Use named exports, not default exports
• File names: kebab-case.ts

Testing Rules

• Every new function needs at least one unit test
• Run npm test before committing
• Do NOT mock the database in integration tests — use a real test DB
• E2E tests live in tests/e2e/

Git Conventions

• Commit style: Conventional Commits (feat:, fix:, docs:, etc.)
• Branch names: feat/short-description or fix/issue-number
• Never force-push to main or develop
• PRs require at least 1 reviewer approval

Important Rules

• Never modify files in generated/ directly — they are auto-generated
• Always use environment variables for secrets; never hardcode them
• Check CHANGELOG.md before making breaking changes
• Run npm run lint before submitting any PR

Preferred Workflow

1. Read relevant files before suggesting changes
2. Write tests before or alongside implementation
3. Keep changes focused; one concern per PR
4. Update docs when adding public-facing features
