How does Module Federation support multi-team collaboration? What are collaboration best practices? - 面试题

Module Federation's multi-team collaboration model requires establishing clear standards and processes. Here is a detailed collaboration solution:

1. Team Organization Architecture

Cross-Team Collaboration Model:

shell
┌─────────────────────────────────────────────┐
│          Platform Team (平台团队)            │
│  - Module Federation Infrastructure          │
│  - Shared Dependency Management              │
│  - CI/CD Pipeline                            │
│  - Code Standards Definition                 │
└──────────────┬──────────────────────────────┘
               │
    ┌──────────┼──────────┬──────────┐
    │          │          │          │
┌───▼───┐ ┌───▼───┐ ┌───▼───┐ ┌───▼───┐
│Order  │ │User   │ │Payment│ │Product│
│Team   │ │Team   │ │Team   │ │Team   │
└───────┘ └───────┘ └───────┘ └───────┘

2. Code Standards and Conventions

Module Naming Conventions:

javascript
// Naming convention: {team}-{module}-{type}
// Example: order-list-component, user-api-service

// Module configuration example
new ModuleFederationPlugin({
  name: 'order-list-component',
  filename: 'remoteEntry.js',
  exposes: {
    './OrderList': './src/components/OrderList',
    './OrderListAPI': './src/api/orderList'
  },
  shared: {
    react: { singleton: true },
    'react-dom': { singleton: true }
  }
})

Directory Structure Standards:

shell
packages/
├── order-list-component/
│   ├── src/
│   │   ├── components/
│   │   │   ├── OrderList.tsx
│   │   │   └── OrderItem.tsx
│   │   ├── api/
│   │   │   └── orderList.ts
│   │   ├── hooks/
│   │   │   └── useOrderList.ts
│   │   ├── types/
│   │   │   └── order.ts
│   │   └── index.ts
│   ├── package.json
│   ├── webpack.config.js
│   └── README.md
├── user-profile-component/
│   └── ...
└── shared-dependencies/
    └── ...

3. API Design Standards

Unified API Interface:

typescript
// types/api.ts
export interface ApiResponse<T> {
  data: T
  code: number
  message: string
}

export interface PaginationParams {
  page: number
  pageSize: number
}

export interface PaginatedResponse<T> extends ApiResponse<T[]> {
  total: number
  page: number
  pageSize: number
}

// Order module API
export interface OrderListParams extends PaginationParams {
  status?: string
  startDate?: string
  endDate?: string
}

export interface Order {
  id: string
  orderNo: string
  status: string
  amount: number
  createdAt: string
}

export const orderAPI = {
  getList: (params: OrderListParams): Promise<PaginatedResponse<Order>> => {
    return request.get('/orders', { params })
  },
  getDetail: (id: string): Promise<ApiResponse<Order>> => {
    return request.get(`/orders/${id}`)
  }
}

4. Version Management Strategy

Semantic Versioning:

json
{
  "name": "order-list-component",
  "version": "1.2.3",
  "description": "Order list component with filtering and pagination",
  "main": "index.js",
  "peerDependencies": {
    "react": "^17.0.0",
    "react-dom": "^17.0.0"
  },
  "dependencies": {
    "@company/shared-types": "^1.0.0"
  }
}

Version Compatibility Matrix:

javascript
// version-matrix.js
const versionMatrix = {
  'order-list-component': {
    '1.x': {
      compatibleHost: ['>=1.0.0'],
      breakingChanges: []
    },
    '2.0.0': {
      compatibleHost: ['>=2.0.0'],
      breakingChanges: [
        'Removed deprecated API methods',
        'Changed component props interface'
      ]
    }
  }
}

export function checkCompatibility(moduleName, moduleVersion, hostVersion) {
  const moduleInfo = versionMatrix[moduleName]
  if (!moduleInfo) return true

  const majorVersion = moduleVersion.split('.')[0]
  const versionInfo = moduleInfo[`${majorVersion}.x`] || moduleInfo[majorVersion]
  
  if (!versionInfo) return false

  return versionInfo.compatibleHost.some(range => 
    semver.satisfies(hostVersion, range)
  )
}

5. Documentation Standards

  subscribe(moduleName, callback) {
    if (!this.subscribers.has(moduleName)) {
      this.subscribers.set(moduleName, [])
    }
    this.subscribers.get(moduleName).push(callback)
  }

  notify(moduleName, change) {
    const callbacks = this.subscribers.get(moduleName) || []
    callbacks.forEach(callback => callback(change))
    
    // Send notification to Slack
    this.sendSlackNotification(moduleName, change)
  }

  sendSlackNotification(moduleName, change) {
    const webhookUrl = process.env.SLACK_WEBHOOK_URL
    const message = {
      text: `Module ${moduleName} has been updated`,
      attachments: [{
        color: 'good',
        fields: [
          { title: 'Version', value: change.version, short: true },
          { title: 'Type', value: change.type, short: true },
          { title: 'Description', value: change.description, short: false }

      }]
    }
    
    fetch(webhookUrl, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(message)
    })
  }
}

export const changeNotificationService = new ChangeNotificationService()

Through this collaboration model, you can establish an efficient Module Federation multi-team collaboration system.
