SIDE-BY-SIDE CODE SAMPLES

Roo Code

.roo/rules/*.md

markdown

# Code Standards

## TypeScript
- Enable strict mode in all tsconfig files
- No `any` types — use `unknown` and narrow
- Prefer interfaces over type aliases for object shapes

## React
- Functional components only
- Use custom hooks for shared stateful logic
- Colocate component, styles, and tests

## Git
- Conventional commits (feat:, fix:, chore:, etc.)
- Keep commits atomic and focused
- Squash merge feature branches

Zed

.rules

markdown

# Project Rules

## Stack
- TypeScript 5.x with strict mode
- React 19 with Server Components
- Tailwind CSS v4
- Drizzle ORM with PostgreSQL

## Code Style
- Prefer named exports over default exports
- Use "use client" directive only when interactivity is required
- Colocate tests in __tests__ directories next to source files
- Use Zod for all runtime validation

## Architecture
- App Router with nested layouts in app/
- Server actions in app/actions/
- Database schema in db/schema.ts
- Shared utilities in lib/

## Commands
- Dev server: pnpm dev
- Type check: pnpm typecheck
- Test: pnpm test
- Lint: pnpm lint

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Roo Code, configure .roo/rules/*.md. If you use Zed, configure .rules. Many projects include config files for multiple tools so each team member can use their preferred editor.
