This workspace includes comprehensive performance optimizations for build times, test execution, and development workflows.

⚡ Quick Performance Commands

Fast Development Workflows

# Optimized development with parallel servers npm run dev:optimized # Super-fast development startup (skip initial build) npm run dev:fast # Quick test validation npm run quick:test # Fast parallel builds npm run build:fast

Performance Analysis

# Full performance report npm run perf:full-report # Build time measurement npm run perf:build-time # Test execution timing npm run perf:test-time # Cache validation npm run cache:validate

Memory-Optimized Operations

# Large-scale builds with increased memory npm run build:memory-efficient # Memory-efficient testing for large suites npm run test:memory-efficient

🏗️ Build Performance Features

Parallel Build System

  • TypeScript + Jekyll Parallel: Build both systems simultaneously
  • Color-coded Output: Easy identification of build stages
  • Memory Optimization: 4GB heap allocation for large projects
  • CI/CD Ready: Optimized workers and timeouts

Cache Optimization

  • TypeScript Incremental: Faster rebuilds with tsbuildinfo
  • Jekyll Cache: Persistent .jekyll-cache directory
  • Playwright Browser Cache: Shared browser installations
  • Smart Cleanup: Performance-aware cache management

🧪 Test Performance Enhancements

Playwright Optimization

  • Dynamic Workers: 6 workers locally, 3 in CI
  • Intelligent Timeouts: 15s timeout for faster feedback
  • Memory Efficient: Optimized trace and video recording
  • Project Separation: Fast smoke tests vs comprehensive suites

Test Execution Strategy

# Smoke tests for quick validation (Chromium only) npm run test:smoke # Memory-optimized test execution npm run test:memory-efficient # CI-optimized test suite npm run test:ci

⚙️ Configuration Files

TypeScript Performance

  • Main Config: ES2022 target with isolatedModules
  • Performance Config: tsconfig.performance.json for development
  • Skip Library Checks: Faster compilation times

Jekyll Optimization

  • Development Config: _config_dev.yml - Fast iteration
  • Production Config: _config_prod.yml - Full optimization
  • Incremental Builds: Enabled with proper cache management

Playwright Enhancement

  • Multi-Project Setup: Separate configs for different test types
  • Resource Optimization: Smart video/trace collection
  • Browser Management: Efficient browser installation and updates

📊 Performance Monitoring

Build Analysis

# Measure build performance npm run build:measure # Generate optimization recommendations npm run perf:check # Cache performance analysis npm run cache:performance

Performance Metrics

  • Build Time Tracking: Automatic timing with recommendations
  • Memory Usage: Monitor and optimize resource consumption
  • Cache Effectiveness: Validation and optimization tools

🚀 CI/CD Performance

GitHub Actions Optimization

  • Multi-level Caching: npm, Playwright, Jekyll, TypeScript
  • Parallel Execution: Optimized job dependencies
  • Performance Reporting: Automated performance summaries

Cache Strategy

# Example cache configuration - uses: actions/cache@v3 with: path: | ~/.npm ~/.cache/ms-playwright docs/.jekyll-cache tsconfig.tsbuildinfo

💡 Performance Best Practices

Development Workflow

  1. Use Optimized Commands: dev:optimized for daily development
  2. Cache Management: Regular cache:validate checks
  3. Memory Awareness: Use memory-efficient commands for large operations
  4. Test Strategy: Use quick:test for rapid validation

Build Optimization

  1. Parallel Builds: Always use build:parallel or build:fast
  2. Environment Specific: Use appropriate dev/prod configurations
  3. Cache Utilization: Preserve cache directories between builds
  4. Resource Monitoring: Regular performance check-ups

Testing Performance

  1. Selective Testing: Use project-specific test runs
  2. Memory Management: Monitor test suite memory usage
  3. Browser Optimization: Efficient browser management scripts
  4. CI Efficiency: Optimized worker and timeout configurations

🎯 Expected Performance Gains

Area Improvement Details
Build Time 30-50% Parallel builds + optimized configs
Test Execution 25-40% Enhanced Playwright configuration
Development Cycle 20-30% Fast dev servers + incremental builds
CI Pipeline 40-60% Advanced caching + parallel execution
Memory Usage 15-25% Optimized heap allocation + cleanup

🔧 Troubleshooting Performance

Common Issues

# Clear all caches if performance degrades npm run cleanup:performance # Validate configuration npm run cache:validate # Check for memory issues npm run perf:check # Regenerate caches npm run cache:force-rebuild

Performance Debugging

  1. Build Analysis: Use build:measure for timing details
  2. Memory Profiling: Monitor heap usage during operations
  3. Cache Issues: Validate cache effectiveness with tools
  4. Test Performance: Analyze test execution patterns

This performance framework ensures optimal development velocity while maintaining production-ready quality standards.
