React Deep Integration Example:

// Using React.lazy and Suspense for micro frontends
const RemoteApp = React.lazy(() => import('remoteApp/App'));

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

// Using React.lazy and Suspense for micro frontends
const RemoteApp = React.lazy(() => import('remoteApp/App'));

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

Framework Adapter Layer Design

// Generic micro frontend adapter
class MicroFrontendAdapter {
  constructor(config) {
    this.name = config.name;
    this.entry = config.entry;
    this.container = config.container;
    this.activeRule = config.activeRule;
  }

  async mount(props) {
    const { name, entry } = this;
    const module = await import(/* @vite-ignore */ entry);
    const app = module[name];
    app.mount(this.container, props);
  }

  async unmount() {
    // Implement unmount logic
  }
}

// Generic micro frontend adapter
class MicroFrontendAdapter {
  constructor(config) {
    this.name = config.name;
    this.entry = config.entry;
    this.container = config.container;
    this.activeRule = config.activeRule;
  }

  async mount(props) {
    const { name, entry } = this;
    const module = await import(/* @vite-ignore */ entry);
    const app = module[name];
    app.mount(this.container, props);
  }

  async unmount() {
    // Implement unmount logic
  }
}

}));

// Initialize in main application
useStore.setState({ user: { id: 1, name: 'Admin' } });

// Use in sub-application
const user = useStore((state) => state.user);

// Using zustand for shared state
import create from 'zustand';

const useStore = create((set) => ({
  user: null,
  setUser: (user) => set({ user }),

Micro Frontend Optimization Practices

Comprehensive Performance and Security Optimization

Performance Optimization Matrix

Optimization Direction	Specific Measures	Expected Benefits
Loading Performance	Code splitting/lazy loading	30-50% reduction in initial load time
Rendering Performance	Virtual lists/SSR optimization	40%+ improvement in first paint speed
Network Performance	Preloading/CDN acceleration	20-30% reduction in network request time
Memory Management	Timely unmounting/garbage collection	25%+ reduction in memory usage

Performance Optimization Example:

// Webpack code splitting configuration
optimization: {
  splitChunks: {
    chunks: 'all',
    cacheGroups: {
      vendors: {
        test: /[\\/]node_modules[\\/]/,
        priority: -10
      },
      default: {
        minChunks: 2,
        priority: -20,
        reuseExistingChunk: true
      }
    }
  }
}

// Webpack code splitting configuration
optimization: {
  splitChunks: {
    chunks: 'all',
    cacheGroups: {
      vendors: {
        test: /[\\/]node_modules[\\/]/,
        priority: -10
      },
      default: {
        minChunks: 2,
        priority: -20,
        reuseExistingChunk: true
      }
    }
  }
}

Security Protection System

CSP Strategy Configuration:

<meta http-equiv="Content-Security-Policy" content="
  default-src 'self';
  script-src 'self' https://cdn.example.com 'unsafe-inline';
  style-src 'self' 'unsafe-inline';
  img-src 'self' data:;
">

<meta http-equiv="Content-Security-Policy" content="
  default-src 'self';
  script-src 'self' https://cdn.example.com 'unsafe-inline';
  style-src 'self' 'unsafe-inline';
  img-src 'self' data:;
">

XSS Protection Solution:

// Sanitize HTML using DOMPurify
import DOMPurify from 'dompurify';

function SafeHtml({ html }) {
  const clean = DOMPurify.sanitize(html);
  return <div dangerouslySetInnerHTML={{ __html: clean }} />;
}

// Sanitize HTML using DOMPurify
import DOMPurify from 'dompurify';

function SafeHtml({ html }) {
  const clean = DOMPurify.sanitize(html);
  return <div dangerouslySetInnerHTML={{ __html: clean }} />;
}

Scalability Design

Architecture Extension Patterns

Functional Modularization:

// Functional module registration mechanism
const modules = new Map();

function registerModule(name, module) {
  modules.set(name, module);
}

function getModule(name) {
  return modules.get(name);
}

// Functional module registration mechanism
const modules = new Map();

function registerModule(name, module) {
  modules.set(name, module);
}

function getModule(name) {
  return modules.get(name);
}

Plugin-Based Architecture:

// Plugin interface definition
interface MicroFrontendPlugin {
  name: string;
  init(app: MicroFrontendApp): void;
  destroy(): void;
}

// Plugin manager
class PluginManager {
  private plugins: MicroFrontendPlugin[] = [];
  
  register(plugin) {
    this.plugins.push(plugin);
    plugin.init(this.app);
  }
  
  unregister(name) {
    const index = this.plugins.findIndex(p => p.name === name);
    if (index >= 0) {
      this.plugins[index].destroy();
      this.plugins.splice(index, 1);
    }
  }
}

// Plugin interface definition
interface MicroFrontendPlugin {
  name: string;
  init(app: MicroFrontendApp): void;
  destroy(): void;
}

// Plugin manager
class PluginManager {
  private plugins: MicroFrontendPlugin[] = [];
  
  register(plugin) {
    this.plugins.push(plugin);
    plugin.init(this.app);
  }
  
  unregister(name) {
    const index = this.plugins.findIndex(p => p.name === name);
    if (index >= 0) {
      this.plugins[index].destroy();
      this.plugins.splice(index, 1);
    }
  }
}

Dynamic Loading Strategy:

// On-demand loading configuration
const loadConfig = {
  critical: ['core-ui', 'auth'], // Critical modules load immediately
  secondary: ['analytics', 'logs'], // Secondary modules load with delay
  onDemand: ['report', 'settings'] // Load on demand
};

// On-demand loading configuration
const loadConfig = {
  critical: ['core-ui', 'auth'], // Critical modules load immediately
  secondary: ['analytics', 'logs'], // Secondary modules load with delay
  onDemand: ['report', 'settings'] // Load on demand
};

Future Development of Micro Frontends

WASM Micro Frontend Example:

// Load WASM module
async function loadWasmModule() {
  const response = await fetch('math.wasm');
  const buffer = await response.arrayBuffer();
  const module = await WebAssembly.compile(buffer);
  const instance = await WebAssembly.instantiate(module);
  
  return instance.exports;
}

// Use WASM for computation
const wasm = await loadWasmModule();
console.log(wasm.add(2, 3)); // 5

// Load WASM module
async function loadWasmModule() {
  const response = await fetch('math.wasm');
  const buffer = await response.arrayBuffer();
  const module = await WebAssembly.compile(buffer);
  const instance = await WebAssembly.instantiate(module);
  
  return instance.exports;
}

// Use WASM for computation
const wasm = await loadWasmModule();
console.log(wasm.add(2, 3)); // 5
