ioBroker server side web sockets
npm install iobroker.ws.serverThis 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
const http = require('http');
const socket = require('./ws');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, {pingInterval: 120000, pingTimeout: 30000});
// 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);
