Best Practices

1. Environment Variable Management

javascript
// .env.development
ELECTRON_START_URL=http://localhost:3000
API_URL=http://localhost:5000

javascript
// .env.production
API_URL=https://api.example.com

javascript
// electron/main.js
const startUrl = process.env.ELECTRON_START_URL || 
                url.format({
                  pathname: path.join(__dirname, '../build/index.html'),
                  protocol: 'file:',
                  slashes: true
                })

2. Hot Reload Configuration

bash
npm install --save-dev electron-reload

javascript
// electron/main.js
if (process.env.NODE_ENV === 'development') {
  require('electron-reload')(__dirname, {
    electron: path.join(__dirname, '..', 'node_modules', '.bin', 'electron'),
    hardResetMethod: 'exit'
  })
}

3. Code Splitting

javascript
// Use React.lazy
const LazyComponent = React.lazy(() => import('./LazyComponent'))

function App() {
  return (
    <React.Suspense fallback={<div>Loading...</div>}>
      <LazyComponent />
    </React.Suspense>
  )
}

Common Questions

Q: How to use React Router in Electron?A: Use React Router normally, but configure history to createHashHistory or use MemoryHistory.

Q: How to handle differences between Electron and Web environments?A: Use environment variables and conditional judgment to distinguish code execution in different environments.

Q: How to optimize Electron app bundle size?A: Use code splitting, Tree Shaking, resource compression and other techniques to optimize bundle size.

Q: How to use Service Worker in Electron?A: Register Service Worker in main process, ensure using it in correct context.
