Web Build Scripts Documentation

Author: Matthew Raymer Date: 2025-07-11 Status: ✅ COMPLETE - Full web build system with PWA and Docker support

Overview

The web build system for TimeSafari provides comprehensive support for web application development, PWA functionality, and containerized deployment. It supports development, testing, and production environments with optimized builds for each use case.

Build Script Integration

Package.json Scripts

The web build system is fully integrated into package.json with the following scripts:

Basic Build Commands

# Development (starts dev server)
npm run build:web:dev      # Development server with hot reload

# Production builds
npm run build:web:test     # Testing environment build
npm run build:web:prod     # Production environment build

Docker Integration

# Docker builds
npm run build:web:docker       # Development + Docker
npm run build:web:docker:test  # Testing + Docker
npm run build:web:docker:prod  # Production + Docker

Utility Commands

# Serve built files locally
npm run build:web:serve    # Build and serve locally

# Legacy command (maintains compatibility)
npm run build:web          # Full build process

Script Usage

Direct Script Usage

The build-web.sh script supports comprehensive command-line options:

# Basic usage
./scripts/build-web.sh [options]

# Environment-specific builds
./scripts/build-web.sh --dev          # Development server

Troubleshooting

Common Issues

Build Failures

# Clean build artifacts
rm -rf dist/

# Reinstall dependencies
npm install

# Rebuild
npm run build:web:prod

Development Server Issues

# Check port availability
lsof -i :8080

# Kill existing process
kill -9 <PID>

# Restart server
npm run build:web:dev

PWA Issues

# Clear service worker
# In browser DevTools > Application > Service Workers
# Click "Unregister"

# Clear browser cache
# In browser DevTools > Application > Storage
# Click "Clear site data"

Debug Mode

Enable verbose logging for web builds:

# Verbose mode
./scripts/build-web.sh --verbose

# Debug environment
DEBUG_MIGRATIONS=1 npm run build:web:dev

Performance Debugging

# Analyze bundle size
npm run build:web:prod
# Check dist/ directory for file sizes

# Analyze performance
# Use browser DevTools > Performance tab
# Use Lighthouse for PWA metrics

Security Considerations

Build Security

• Environment Isolation: Separate dev/test/prod environments
• Secret Management: Secure handling of API keys
• Dependency Scanning: Regular security audits
• Content Security Policy: CSP headers for security

Runtime Security

• HTTPS Only: Production requires HTTPS
• CSP Headers: Content Security Policy enforcement
• Service Worker Security: Secure service worker implementation
• API Security: Secure API communication

Deployment Options

# Build for production
npm run build:web:prod

# Deploy to static host
# Upload dist/ directory to web server

Docker Deployment

# Build Docker image
npm run build:web:docker:prod

# Deploy to container platform
docker run -p 80:80 timesafari-web:production

CDN Deployment

# Build for production
npm run build:web:prod

# Upload to CDN
# Configure CDN for PWA support

Future Enhancements
