⚠️ React Projects: Avoiding Blank Screens

Important: If your React/Vite APK shows a white/blank screen, you need to add the legacy plugin for Android WebView compatibility.

npm install -D @vitejs/plugin-legacy terser

// vite.config.js
import legacy from '@vitejs/plugin-legacy'

export default defineConfig({
  plugins: [
    react(),
    legacy({ targets: ['chrome >= 52', 'android >= 5'] })
  ],
  base: './'  // Required for APK!
})

🚀 Quick Start

Option 1: Docker Deployment (Linux Server)

Deploy to your Linux server in 3 minutes using pre-built Docker images.

⚠️ Docker images only support linux/amd64. For macOS, use Local Development.

# 1. Create deployment directory
mkdir -p ~/demo2apk && cd ~/demo2apk

# 2. Download deployment config
curl -O https://raw.githubusercontent.com/DeadWaveWave/demo2apk/main/docker-compose.deploy.yml

# 3. Start services
docker compose -f docker-compose.deploy.yml up -d

Visit http://127.0.0.1:5173 to use the Web UI.

Update to latest version:

docker compose -f docker-compose.deploy.yml pull && docker compose -f docker-compose.deploy.yml up -d

Option 2: Local Development (macOS / Linux)

For macOS users or local development:

# 1. Install dependencies
pnpm install

# 2. Start Redis
docker run -d -p 6379:6379 redis:alpine

# 3. Build project
pnpm build

# 4. Start all services (in separate terminals)
pnpm dev        # API Server (port 3000)
pnpm worker     # Build Worker
pnpm frontend   # Web UI (port 5173)

Visit http://localhost:5173 to use the Web UI.

Option 2: API Usage

If you prefer CLI or script integration, use our REST API.

Single HTML File:

curl -X POST http://localhost:3000/api/build/html \
  -F "file=@test-demo.html" \
  -F "appName=TestDemo"

React Project:

# Zip your project first
zip -r test-react-app.zip test-react-app/

# Upload and build (Auto-detects project type)
curl -X POST http://localhost:3000/api/build/zip \
  -F "file=@test-react-app.zip" \
  -F "appName=TestReactApp"

Paste Code:

# Upload raw code (HTML/JS/React)
curl -X POST http://localhost:3000/api/build/code \
  -F "code=<export default function App() { return <h1>Hello</h1> }" \
  -F "appName=MyReactApp"

See API Documentation for details.

⚙️ Configuration

Rate Limiting

To ensure fair usage, rate limiting is enabled by default:

• Limit: Max 5 requests per hour per IP.
• Dev Mode: Can be disabled via environment variables for local development.

Set in .env:

# Disable rate limiting (dev/test only)
RATE_LIMIT_ENABLED=false

# Custom limit (default 5)
RATE_LIMIT_MAX=10

File Retention

To save storage and protect user data:

• Retention: Generated APKs and temp files are deleted after 2 hours.
• Cleanup: Background worker scans for expired files every 30 minutes (configurable).

Configure via environment variable:

# Retention period (hours)
FILE_RETENTION_HOURS=2

# Whether to delete Cordova/Capacitor work dirs after each build
CLEANUP_BUILD_ARTIFACTS=true

# Worker-side cleanup of old APKs/builds (in BUILDS_DIR)
FILE_CLEANUP_ENABLED=true
FILE_CLEANUP_INTERVAL_MINUTES=30

Concurrency & Queuing

Control how many builds run simultaneously. Excess builds will be queued automatically.

# Number of concurrent builds (default 2)
WORKER_CONCURRENCY=2
