Node.js Question
next() call in express-ws module in nodejs
I came across a sample code for my webserver using express-ws for reliable Websocket connection between my server and client browser. The code will start listening in port 3000 for websocket connection.
var express = require('express');
var app = express();
var expressWs = require('express-ws')(app);
app.use(function (req, res, next) {
console.log('middleware');
req.testing = 'testing';
return next();
});
app.get('/', function(req, res, next){
console.log('get route', req.testing);
res.end();
});
app.ws('/', function(ws, req) {
ws.on('message', function(msg) {
console.log(msg);
});
console.log('socket', req.testing);
});
server.listen(3000);
what is the use of next() API in express-websocket?
