Javascript 在es6中，将带有回调的事件侦听器设置为iterable

我的websocket类，

Wws

，使用

onmessage

侦听所有传入的消息

对于使用我的websocket模块

Wws

的程序，我希望它们通过

iterable

s“侦听”

比如说,

// listen for new blog messages let itr = ws.listen( 'blog', 'new' ); // display each new blog as we receive it while( true ) { let blog = itr.next().value; dispBlog( blog ); }

如何将带有

回调的
侦听器
转换为
迭代器
？
for…of
正在阻塞。只要您处于该循环中，它就会阻止服务器执行任何其他操作，包括接受新请求。“你不想那样做的。”托菲-谢谢-不知道。更改为
then（）
ws = function() {
  conn = new Websocket(...);

  // could have global `onmessage` that passes through the messages
  conn.onmessage = function(msg) {
    // can look at listeners and know there are iterators
    // but how to talk to them?
  }
  listeners = new Map();

  // generator for listening to incoming messages
  listener = function*( service, action ) {
    // can add this service.action to listeners, but what?
    // does this guy create his own `onmessage`?
    // if so, how does he get the `yield` to the outer function?
  }
