# 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:

```json
// 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:

```json
// 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

```bash
#!/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)
```bash
./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
```bash
./scripts/build-web.sh --test
```
- Test environment configuration
- Minimal minification
- Source maps enabled
- Uses `.env.test` file
- **PWA enabled** for testing

### Production Mode
```bash
./scripts/build-web.sh --prod
```
- Full production optimizations
- Maximum minification
- Source maps disabled
- Uses `.env.production` file
- **PWA enabled** with full caching strategies

## Docker Integration

### Docker Build Options
```bash
# Development + Docker
./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
```bash
./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
```bash
./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
```bash
# 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
```bash
# Development + Docker
npm run build:web:docker

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

# Production + Docker
npm run build:web:docker:prod
```

### Direct Script Usage
```bash
# Show help
./scripts/build-web.sh --help

# Show environment variables
./scripts/build-web.sh --env

# Verbose logging
./scripts/build-web.sh --test --verbose
```

## Benefits Achieved

## Conclusion

The `build-web.sh` script successfully addresses the requirement to prevent scripts from having multiple commands with flags while providing a robust, maintainable, and feature-rich build system for the TimeSafari web application.

The implementation follows established patterns in the codebase, leverages existing utilities, and provides a consistent developer experience across all build modes and platforms.
