🚀 Quick Start

Initial Setup

# Make scripts executable and run setup
npm run setup

# Or manually:
chmod +x scripts/*.sh
./scripts/setup-dev-env.sh

Development Workflow

# Start development mode
npm run dev

# Run quality checks
npm run validate

# Performance testing
npm run perf

# Security scanning  
npm run security

# Package for testing
npm run package:dev

Deployment Commands

# Deploy to different environments
npm run deploy:dev      # Development build
npm run deploy:staging  # Staging environment
npm run deploy:prod     # Production (Chrome Web Store)

# Version management
npm run release:patch   # 1.0.0 → 1.0.1
npm run release:minor   # 1.0.0 → 1.1.0  
npm run release:major   # 1.0.0 → 2.0.0

🔧 Pipeline Architecture

CI/CD Flow

Pull Request → Quality Gates → Security Scan → Build → Performance Test → Deploy

Quality Gates (All must pass)

  • ✅ TypeScript: Strict mode compliance
  • ✅ Linting: Biome code standards
  • ✅ Testing: 80%+ coverage required
  • ✅ Security: No high-severity vulnerabilities
  • ✅ Performance: <30s build, <500KB bundle

Deployment Environments

  1. Development - Local testing with source maps
  2. Staging - Pre-production validation
  3. Production - Chrome Web Store deployment

🛡️ Security Implementation

Automated Security Checks

  • Manifest validation - Permission auditing
  • Code scanning - Pattern detection for vulnerabilities
  • Dependency auditing - npm audit integration
  • Build verification - Production artifact validation
  • Privacy compliance - PII and tracking detection

Security Standards

  • Manifest V3 compliance
  • CSP validation
  • No eval() or innerHTML usage
  • Input sanitization checks
  • Sensitive data pattern detection

📊 Monitoring & Observability

Production Telemetry

import { telemetry } from '@/core/telemetry';

// Track performance
const timer = telemetry.startTimer('operation_name');
// ... do work
timer(); // Automatically records duration

// Track errors
telemetry.reportError(error, { context: 'user_action' });

// Track user events
telemetry.trackUserEvent('feature_used', { feature: 'context_extraction' });

Key Metrics Tracked

  • Extension load time
  • Memory usage
  • Network requests
  • User interactions
  • Error rates
  • Performance benchmarks

🎯 Quality Standards

Code Quality

  • TypeScript: Strict mode with all flags enabled
  • Test Coverage: Minimum 80% required
  • Bundle Size: Maximum 500KB
  • Build Time: Under 30 seconds
  • No Debug Code: Automatic detection and blocking

Performance Benchmarks

  • Service worker startup: <100ms
  • Content script injection: <50ms
  • Memory usage: <10MB baseline
  • Bundle optimization: Tree shaking enabled

📈 Development Experience

IDE Integration (VS Code)

  • Biome formatter/linter integration
  • TypeScript strict mode support
  • Debugging configurations
  • Task automation
  • Extension recommendations

Git Workflow

  • Pre-commit hooks: Automatic quality checks
  • Conventional commits: Standardized commit messages
  • Branch protection: Quality gates enforcement
  • Auto-formatting: Code style consistency

Developer Commands

# Quality checks
npm run validate        # Full validation suite
npm run typecheck      # TypeScript validation
npm run lint:fix       # Auto-fix linting issues
npm run format         # Code formatting

# Testing
npm run test           # Interactive test mode
npm run test:coverage  # Coverage reporting
npm run test:ui        # Visual test interface

# Performance
npm run perf           # Full performance suite
npm run perf:build     # Build time analysis
npm run perf:size      # Bundle size analysis

🚀 Deployment Strategy

Multi-Environment Pipeline

  1. Feature Branch → Development build + validation
  2. Staging Branch → Pre-production testing
  3. Main Branch → Production deployment to Chrome Web Store

Automated Deployment

# Automatic version bump and deployment
git tag v1.2.3
git push origin v1.2.3
# → Triggers production deployment pipeline

Rollback Strategy

# Emergency rollback
node scripts/deploy.js rollback 1.2.2 production
