通用 JS 模块封装

通用的 JS 模块封装，支持所有 js 运行环境：web、微信小程序、react-native

功能

WebSocket

使用示例

const webSocketClient = new WebSocketClient(
  {
    uri,
  },
  window.WebSocket,
)

webSocketClient.traceFunction = data => console.debug('WebSocketClient', data)

webSocketClient.onConnected = reconnect => {
  console.log('WebSocketClient', 'websocket连接成功, reconnect: ' + reconnect)
}

webSocketClient.onDisconnect = () => {
  console.log('WebSocketClient', 'websocket连接已关闭')
}

webSocketClient.onMessage = msg => {
  try {
    const data = JSON.parse(msg)
    console.log(data)
  } catch (err) {}
}

webSocketClient.connect({
  onFailure: data => {
    console.log('WebSocketClient', 'websocket 连接失败:', data)
  },
})

工具类

async-factory

异步工厂，用于生产单例对象，异步环境下可安全调用。

使用示例

class Connection {
  constructor(options) {
    this.options = options
  }
}

const init = options => {
  return new Promise(resolve => {
    const conn = new Connection(options)

    setTimeout(() => resolve(conn), 2000)
  })
}

const asyncInitiator = asyncFactory(ConnectionManager.initConnection, 30 * 1000)

const sharedInstance = asyncInitiator(options)
