🔧 Environment​

Development Environment - Setup and configuration:

  • Local development setup
  • Docker containerization
  • Environment variables management
  • IDE configuration and extensions
  • Git hooks and pre-commit setup
  • Package management and dependencies

⏳ Performance​

Performance Tools - Optimization and monitoring:

  • Bundle analysis and optimization
  • Performance profiling tools
  • Memory usage monitoring
  • Network performance analysis
  • Lighthouse integration
  • Performance budgets and alerts

🔍 Debugging​

Debugging Tools - Troubleshooting and diagnostics:

  • Browser DevTools configuration
  • React DevTools usage
  • Network debugging
  • Error tracking and logging
  • Performance debugging
  • Production debugging strategies

🛠️ Essential Tools​

Development Environment​

  • Node.js (v18+) - JavaScript runtime
  • Yarn - Package manager
  • Docker - Containerization
  • Git - Version control
  • VS Code - Recommended IDE

Build Tools​

  • Next.js - React framework
  • TypeScript - Type safety
  • ESLint - Code linting
  • Prettier - Code formatting
  • Husky - Git hooks

Testing Tools​

  • Jest - Unit testing
  • Playwright - E2E testing
  • React Testing Library - Component testing
  • MSW - API mocking

Performance Tools​

  • Lighthouse - Performance auditing
  • Bundle Analyzer - Bundle analysis
  • React Profiler - Component performance
  • Chrome DevTools - Browser debugging

🚀 Quick Setup​

1. Prerequisites​

# Install Node.js (v18+)
node --version

# Install Yarn
npm install -g yarn

# Install Docker
docker --version

2. Project Setup​

# Clone repository
git clone https://github.com/Underwood-Inc/idling.app__UI.git
cd idling.app__UI

# Install dependencies
yarn install

# Set up environment
cp .env.example .env.local

# Start development server
yarn dev

3. IDE Configuration​

VS Code Extensions:

  • ES7+ React/Redux/React-Native snippets
  • TypeScript Hero
  • Prettier - Code formatter
  • ESLint
  • GitLens
  • Auto Rename Tag
  • Bracket Pair Colorizer

📊 Performance Monitoring​

Metrics to Track​

  • Bundle Size - Keep under 500KB
  • First Contentful Paint - Under 1.5s
  • Largest Contentful Paint - Under 2.5s
  • Time to Interactive - Under 3.5s
  • Cumulative Layout Shift - Under 0.1

Monitoring Tools​

  • Lighthouse CI - Automated performance testing
  • Web Vitals - Core performance metrics
  • Bundle Analyzer - Bundle size analysis
  • React Profiler - Component performance

🐛 Debugging Strategies​

Common Issues​

  1. Performance Problems

    • Use React Profiler to identify slow components
    • Check for unnecessary re-renders
    • Optimize bundle size

  2. Memory Leaks

    • Monitor memory usage in DevTools
    • Check for event listener cleanup
    • Analyze component lifecycle

  3. Network Issues

    • Use Network tab in DevTools
    • Check API response times
    • Verify caching strategies

🔗 Tool Configuration​

ESLint Configuration​

{
  "extends": [
    "next/core-web-vitals",
    "@typescript-eslint/recommended",
    "prettier"
  ],
  "rules": {
    "prefer-const": "error",
    "no-unused-vars": "error",
    "@typescript-eslint/no-explicit-any": "warn"
  }
}

Prettier Configuration​

{
  "semi": true,
  "trailingComma": "es5",
  "singleQuote": true,
  "printWidth": 80,
  "tabWidth": 2,
  "useTabs": false
}
