Sample AI Powered Sdlc Patterns With AWS

React + Vite Skill

Domain-specific guidance for building React applications with Vite.

Project Setup

• Create files manually instead of using create-vite (it prompts interactively)
• Minimum files: index.html, vite.config.js, src/main.jsx, src/App.jsx, package.json
• Use "type": "module" in package.json for ESM

Patterns

• Use functional components with hooks, never class components
• Prefer useState and useReducer for local state
• Use useEffect cleanup functions to prevent memory leaks
• Keep components small — extract when a component exceeds ~100 lines

Styling

• Prefer CSS Modules (*.module.css) or Tailwind CSS
• Avoid inline styles for anything beyond trivial one-offs

Testing

• Use Vitest (not Jest) — it's Vite-native and faster
• Use @testing-library/react for component tests
• Run tests with npx vitest --run (not watch mode)
• Use Playwright for E2E tests: npx playwright test (headless)

Build & Deploy

• npm run build produces dist/ directory
• Preview with npx serve dist (background it with &)
• Never run npm run dev in automation — it blocks

Common Gotchas

• Vite uses import.meta.env not process.env for environment variables
• Prefix env vars with VITE_ for client-side access
• Hot module replacement only works in dev mode
• @vitejs/plugin-react is required in vite.config.js for JSX
