如何使用 TypeScript 扩展 Node.js 中的 WebSocket 类型？

我正在尝试扩展以下 WebSockethttps://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/ws/index.d.ts https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/ws/index.d.ts

无论我尝试什么，我似乎都无法向 WebSocket 添加新属性

// Messes with other typings in the WebSocket
declare module "ws" {
  // Tried declare class MyWebSocket extends WebSocket too
  interface WebSocket {
    id: string;
  }
}

wss.on("connection", socket => {
  const id = uuidv4();
  socket.id = id

  socket.on("message", data => {

我在网上看到很多人遇到这个问题，但找不到详细的解决方案

创建自定义界面 -ExtWebSocket，接口将扩展WebSocket。然后投射你的socket as ExtWebSocket。不需要declare module.

interface ExtWebSocket extends WebSocket {
  id: string; // your custom property
}

Usage

wss.on("connection", (socket: ExtWebSocket) => { // here
  const id = uuidv4();
  socket.id = id;

  socket.on("message", data => {
    // do something
  })
});
