@iobroker/ws-server

This library is used for communication with front-end via pure web-sockets.

It simulates socket.io interface.

It is used normally together with @iobroker/ws on browser side, and it is not compatible with socket.io.client library

Usage

const http = require('http');
const socket = require('@iobroker/ws-server');

const requestListener = function (req, res) {
  res.writeHead(200);
  res.end('Hello, World!');
};

// create web server
const webServer    = http.createServer(requestListener);
// create web socket server
const socketServer = socket.listen(webServer);

// install event handlers on socket connection
function onConnection(socket, initDone) {
    console.log('==> Connected IP: ' + socket.connection.remoteAddress);
    
    socket.on('message', function (data, cb) {
        console.log('Received ' + data);
        cb(data + 1);
    });
    
    socket.on('disconnect', function (error) {
        console.log(`<== Disconnect from ${socket.connection.remoteAddress}: ${error}`);
    });
    
    initDone && initDone();
}

// install event handlers of the socket server
socketServer.on('connection', onConnection);
socketServer.on('error', (e, details) => console.error(`Server error: ${e}${details ? ' - ' + details : ''}`));

// start web server
webServer.listen(5000);
