Build Web Script Integration

Author: Matthew Raymer Date: 2025-07-11 Status: ✅ COMPLETE - Successfully implemented and tested

Overview

The build-web.sh script has been successfully integrated into the TimeSafari build system, providing a unified approach to web builds that eliminates the need for multiple commands with flags in npm scripts.

Problem Solved

Previous Issue: Multiple Commands with Flags

The original package.json scripts had complex command chains that made debugging and maintenance difficult:

// OLD PATTERN - Multiple commands with flags
"build:web:test": "npm run build:web:build -- --mode test",
"build:web:prod": "npm run build:web:build -- --mode production",
"build:web:docker:test": "npm run build:web:docker -- --mode test",
"build:web:docker:prod": "npm run build:web:docker -- --mode production"

New Solution: Single Script with Arguments

The new approach uses a single shell script that handles all build modes and options:

// NEW PATTERN - Single script calls
"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",
"build:web:docker": "./scripts/build-web.sh --docker",
"build:web:docker:test": "./scripts/build-web.sh --docker:test",
"build:web:docker:prod": "./scripts/build-web.sh --docker:prod",
"build:web:serve": "./scripts/build-web.sh --serve"

Script Architecture

Design Principles

1. Single Responsibility: Each npm script calls exactly one command
2. Argument Parsing: All complexity handled within the shell script
3. Consistent Interface: Follows the same pattern as other build scripts
4. Environment Management: Proper environment variable handling
5. Error Handling: Comprehensive error checking and reporting
6. Development-First: Development mode starts dev server instead of building

Script Structure

#!/bin/bash
# build-web.sh
# Author: Matthew Raymer
# Description: Web build script for TimeSafari application

# Exit on any error
set -e

# Source common utilities
source "$(dirname "$0")/common.sh"

# Parse arguments and set build mode
parse_web_args "$@"

# Validate environment
validate_web_environment

# Setup environment
setup_build_env "web"
setup_web_environment

# Execute build steps
clean_build_artifacts "dist"
execute_vite_build "$BUILD_MODE"

# Optional steps
if [ "$DOCKER_BUILD" = true ]; then
    execute_docker_build "$BUILD_MODE"
fi

if [ "$SERVE_BUILD" = true ]; then
    serve_build
fi

Build Modes Supported

Development Mode (Default)

./scripts/build-web.sh
./scripts/build-web.sh --dev

• Starts Vite development server with hot reload
• No build step - runs development server directly
• Fast startup with live reload capabilities
• Available at http://localhost:8080
• Source maps enabled for debugging
• PWA enabled for development testing

Test Mode

./scripts/build-web.sh --test

• Test environment configuration
• Minimal minification
• Source maps enabled
• Uses .env.test file
• PWA enabled for testing

Production Mode

./scripts/build-web.sh --prod

• Full production optimizations
• Maximum minification
• Source maps disabled

./scripts/build-web.sh --docker

# Test + Docker
./scripts/build-web.sh --docker:test

# Production + Docker
./scripts/build-web.sh --docker:prod

Docker Features

• Automatic image tagging (timesafari-web:mode)
• Build argument passing
• Environment-specific configurations
• Consistent image naming

Local Development

Development Server

./scripts/build-web.sh
./scripts/build-web.sh --dev

• Starts Vite development server with hot reload
• No build step required
• Fast startup (~350ms)
• Available at http://localhost:8080
• Supports live reload and HMR
• Source maps enabled for debugging

Serve Build Locally

./scripts/build-web.sh --serve

• Builds the application first
• Starts a local HTTP server to serve the built files
• Supports Python HTTP server or npx serve
• Runs on port 8080

PWA Configuration

PWA Best Practices Implementation

The TimeSafari web build follows PWA best practices by enabling PWA functionality across all environments:

✅ Development Mode

• PWA enabled for development testing
• Service worker registration active
• Manifest generation enabled
• Hot reload compatible

✅ Test Mode

• PWA enabled for QA testing
• Service worker registration active
• Manifest generation enabled
• Full PWA feature testing

✅ Production Mode

• PWA enabled with full caching strategies
• Service worker registration active
• Manifest generation enabled
• Runtime caching for API calls
• Optimized for production performance

PWA Features Generated

• manifest.webmanifest - PWA manifest with app metadata
• sw.js - Service worker for offline functionality
• workbox-*.js - Workbox library for caching strategies
• Share target support for image sharing
• Offline-first architecture

Visual Confirmations of PWA Installation

✅ Automatic Browser Prompts

• Chrome: Install banner in address bar with install button
• Safari: "Add to Home Screen" prompt
• Edge: Install button in toolbar
• Firefox: Install button in address bar

✅ Custom Install Prompt

• PWAInstallPrompt Component: Shows when PWA can be installed
• Install Button: Prominent blue "Install" button
• Dismiss Options: "Later" button and close button
• Success Notification: Confirms successful installation

✅ Post-Installation Indicators

• App Icon: Appears on device home screen/start menu
• Standalone Window: Opens without browser UI
• Native Experience: Full-screen app-like behavior
• Offline Capability: Works without internet connection

✅ Installation Status Detection

• Display Mode Detection: Checks for standalone/fullscreen modes
• Service Worker Status: Monitors service worker registration
• Install Event Handling: Listens for successful installation
• Environment Awareness: Only shows when PWA is enabled

Environment Variables Set

• VITE_PLATFORM=web
• VITE_PWA_ENABLED=true
• VITE_DISABLE_PWA=false
• NODE_ENV (based on build mode)
• VITE_GIT_HASH (from git)

Environment Management

Environment File Loading

The script automatically loads environment files based on build mode:

1. .env.{mode} (e.g., .env.test, .env.production)
2. .env (fallback)

Integration with Existing System

Common Utilities

The script leverages the existing common.sh utilities:

• log_info, log_success, log_error - Consistent logging
• measure_time - Performance tracking
• safe_execute - Error handling
• setup_build_env - Environment setup
• clean_build_artifacts - Cleanup operations

Consistent Patterns

Follows the same patterns as other build scripts:

• build-electron.sh - Electron builds
• build-android.sh - Android builds
• build-ios.sh - iOS builds

Usage Examples

Basic Builds

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

# Test environment build
npm run build:web:test

# Production build
npm run build:web:prod

Docker Builds

# Development + Docker

# Test + Docker
npm run build:web:docker:test

# Production + Docker
