SIDE-BY-SIDE CODE SAMPLES

Amazon Q Developer

.amazonq/rules/*.md

markdown

# React Component Standards

## Purpose
Ensure consistent React component patterns across the frontend codebase.

## Priority
High

## Instructions
- Use functional components with TypeScript
- Define props interfaces above the component
- Use React.FC only when children are expected
- Colocate styles using CSS Modules (*.module.css)
- Extract hooks into separate files when reused
- Memoize expensive computations with useMemo
- Use React.lazy for route-level code splitting

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

KEY DIFFERENCES

1. Global config

WHICH SHOULD I USE?

Recommendation

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