TimeSafari Build Systems Overview

Author: Matthew Raymer Date: 2025-07-11 Status: ✅ COMPLETE - All build systems documented and integrated

Overview

TimeSafari supports multiple platforms and build targets through a unified build system architecture. This document provides a comprehensive overview of all build systems, their purposes, and how they work together.

Build System Architecture

Platform Support Matrix

Platform	Build Script	Development	Testing	Production	Package Types
Web	build-web.sh	✅ Dev Server	✅ Test Build	✅ Prod Build	Docker Images
Android	build-android.sh	✅ Debug APK	✅ Test APK	✅ Release APK/AAB	APK, AAB
iOS	build-ios.sh	✅ Debug App	✅ Test App	✅ Release App	IPA
Electron	build-electron.sh	✅ Dev App	✅ Test App	✅ Prod App	AppImage, DEB, DMG, EXE

Build Script Locations

scripts/
├── build-web.sh          # Web/PWA builds
├── build-android.sh      # Android mobile builds
├── build-ios.sh          # iOS mobile builds (future)
├── build-electron.sh     # Desktop builds
└── common.sh             # Shared build utilities

Unified Build Pattern

All build scripts follow a consistent pattern:

1. Environment Setup

# Set platform-specific environment variables
VITE_PLATFORM=<platform>
PWA: automatically enabled for web platforms
VITE_GIT_HASH=<git-commit-hash>

2. Argument Parsing

# Consistent command-line interface
./scripts/build-<platform>.sh [--dev|--test|--prod] [options]

3. Build Process

# Standard build flow
1. Validate environment
2. Clean build artifacts
3. Build web assets (Vite)
4. Platform-specific build
5. Generate assets
6. Create packages (if requested)

4. Error Handling

# Consistent exit codes
1: Cleanup failed
2: Web build failed
3: Platform build failed
4: Asset generation failed
5: Package creation failed

Web Build System

Purpose

Builds the web application for browser and PWA deployment.

Key Features

• Development Server: Hot reload with Vite
• PWA Support: Service workers and manifest generation
• Docker Integration: Containerized deployment
• Environment Modes: Development, test, production

Usage Examples

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

# Production build
npm run build:web:prod

# Docker deployment
npm run build:web:docker:prod

Output

• Development: Vite dev server at http://localhost:8080
• Production: Static files in dist/ directory
• Docker: Containerized application image

Documentation: Web Build Scripts Guide

Android Build System

Purpose

Builds Android mobile applications using Capacitor and Gradle.

Key Features

• Capacitor Integration: Web-to-native bridge
• Gradle Builds: APK and AAB generation
• Asset Generation: Icons and splash screens
• Device Deployment: Direct APK installation

Usage Examples

# Development build
npm run build:android:dev

# Production APK
npm run build:android:prod

# Deploy to device
npm run build:android:deploy

Output

• Debug APK: android/app/build/outputs/apk/debug/app-debug.apk
• Release APK: android/app/build/outputs/apk/release/app-release.apk
• AAB Bundle: android/app/build/outputs/bundle/release/app-release.aab

Device Deployment

# Automatic deployment to connected device
npm run build:android:deploy

# Manual deployment
adb install -r android/app/build/outputs/apk/debug/app-debug.apk

Documentation: Android Build Scripts Guide

iOS Build System

Purpose

Builds iOS mobile applications using Capacitor and Xcode.

Key Features

Electron Build System

Purpose

Builds desktop applications for Windows, macOS, and Linux.

Key Features

• Cross-Platform: Windows, macOS, Linux support
• Package Formats: AppImage, DEB, DMG, EXE
• Development Mode: Direct app execution
• Single Instance: Prevents multiple app instances

Usage Examples

# Development (runs app directly)
npm run build:electron:dev

# Production AppImage
npm run build:electron:appimage:prod

# Production DMG
npm run build:electron:dmg:prod

Output

• Development: App runs directly (no files created)
• Packages: Executables in electron/dist/ directory
  • AppImage: TimeSafari-1.0.3-beta.AppImage
  • DEB: TimeSafari_1.0.3-beta_amd64.deb
  • DMG: TimeSafari-1.0.3-beta.dmg
  • EXE: TimeSafari Setup 1.0.3-beta.exe

Documentation: Electron Build Scripts Guide

Environment Management

Environment Variables

All build systems use consistent environment variable patterns:

# Platform identification
VITE_PLATFORM=web|capacitor|electron

# PWA configuration
PWA: automatically enabled for web platforms

# Build information
VITE_GIT_HASH=<git-commit-hash>
DEBUG_MIGRATIONS=0|1

Environment Files

.env.development    # Development environment
.env.test          # Testing environment
.env.production    # Production environment

Mode-Specific Configuration

Each build mode loads appropriate environment configuration:

• Development: Local development settings
• Test: Testing environment with test APIs
• Production: Production environment with live APIs

Package.json Integration

Script Organization

All build scripts are integrated into package.json with consistent naming:

{
  "scripts": {
    // Web builds
    "build:web": "./scripts/build-web.sh",
    "build:web:dev": "./scripts/build-web.sh --dev",
    "build:web:test": "./scripts/build-web.sh --test",
    "build:web:prod": "./scripts/build-web.sh --prod",
    
    // Android builds
    "build:android": "./scripts/build-android.sh",
    "build:android:dev": "./scripts/build-android.sh --dev",
    "build:android:test": "./scripts/build-android.sh --test",
    "build:android:prod": "./scripts/build-android.sh --prod",
    
    // iOS builds
    "build:ios": "./scripts/build-ios.sh",
    "build:ios:dev": "./scripts/build-ios.sh --dev",
    "build:ios:test": "./scripts/build-ios.sh --test",
    "build:ios:prod": "./scripts/build-ios.sh --prod",
    
    // Electron builds
    "build:electron:dev": "./scripts/build-electron.sh --dev",
    "build:electron:test": "./scripts/build-electron.sh --test",
    "build:electron:prod": "./scripts/build-electron.sh --prod"
  }
}

Legacy Compatibility

Legacy scripts are maintained as aliases for backward compatibility:

{
  "scripts": {
    // Legacy Android scripts (aliases)
    "build:capacitor:android": "npm run build:android",
    "build:capacitor:android:dev": "npm run build:android:dev",
    "build:capacitor:android:test": "npm run build:android:test",
    "build:capacitor:android:prod": "npm run build:android:prod"
  }
}

Build Artifacts

Common Artifacts

All build systems generate consistent artifacts:

dist/                    # Web build output
├── index.html          # Main HTML file
├── assets/             # Compiled assets
├── manifest.webmanifest # PWA manifest
└── sw.js              # Service worker

android/app/build/      # Android build output
├── outputs/apk/debug/  # Debug APKs
├── outputs/apk/release/ # Release APKs
└── outputs/bundle/release/ # AAB bundles

ios/App/build/          # iOS build output
├── Debug-iphonesimulator/ # Debug builds
└── Release-iphoneos/   # Release builds

electron/dist/          # Electron packages
├── *.AppImage          # Linux AppImages

├── *.dmg              # macOS DMG packages
└── *.exe              # Windows installers

Asset Generation

All platforms generate platform-specific assets:

# Icons and splash screens
npx capacitor-assets generate --android
npx capacitor-assets generate --ios

# PWA assets
npx vite build --config vite.config.web.mts

Development Workflow

Daily Development

# Web development
npm run build:web:dev      # Starts dev server

# Android development
npm run build:android:dev  # Builds debug APK
npm run build:android:deploy # Deploy to device

# Electron development
npm run build:electron:dev # Runs app directly

Testing Workflow

# Test all platforms
npm run build:web:test
npm run build:android:test
npm run build:ios:test
npm run build:electron:test

Production Workflow

# Build all platforms for production
npm run build:web:prod
npm run build:android:prod
npm run build:ios:prod
npm run build:electron:prod

# Create distribution packages
npm run build:electron:appimage:prod
npm run build:electron:dmg:prod
npm run build:electron:deb:prod

Troubleshooting

Common Issues

Build Failures

# Clean all build artifacts
npm run clean:all

# Rebuild from scratch
npm run build:<platform>:dev

Device Connection Issues

# Check Android device connection
adb devices

# Check iOS device connection
xcrun devicectl list devices

Environment Issues

# Verify environment variables
echo $VITE_PLATFORM
echo "PWA: automatically enabled for web platforms"

# Check environment files
ls -la .env*

Debug Mode

Enable verbose logging for all build scripts:

# Verbose mode
./scripts/build-<platform>.sh --verbose

# Debug environment
DEBUG_MIGRATIONS=1 npm run build:<platform>:dev
