AsyncSocket is a simple implementation of WS communication using asynchronous methods.
It consists of a Node.js module, Web and WebMin.
An AsyncSocketServer is implemented for Node.js, the main difference from a regular WebSocket.Server is that the "connection" event returns an AsyncSocket.
AsyncSocket is the same WebSocket client, but implements its own "message" event and methods: send, sendNoReply, sendEmit.
//Server side
const wss = new AsyncSocketServer({port: 8080});
wss.on('connection', wsc=> {
console.log("New connect");
wsc.on('message', mess=>{
if(mess.testReply) return mess.reply({message: "Great"});
else console.log(mess);
});
});
//Client side
const wsc = await AsyncSocketClient(new WebSocket('ws://localhost:8080'));
//or
const ws = new WebSocket('ws://localhost:8080');
const wsc = await new Promise((resolve, reject) => {
ws.on('open', async () => {
const wsc = new AsyncSocket(ws);
resolve(wsc);
});
});
wsc.on('message', console.log);
const data = await wsc.send({testReply: true});
console.log(data.message); //=>"Great"
It is also possible to transfer events using the sendEmit method.
//Server side
wss.on('connection', wsc=> {
console.log("New connect");
setInterval(()=>{
wsc.sendEmit('interval', {message: "Great"})
},5000);
});
//Client side
wsc.on('interval', data=>console.log(data.message)); //=>"Great" Every 5 seconds
