Getting ready

Express is so minimalistic that it doesn't come with any boilerplate code to get you started. There are a number of generators out there which can set up a structure for you, however, I'm going to stick to a simple web page and a WebSocket for testing. Here's my Express file:

var express = require('express'); 
var app = express(); 
var expressWs = require('express-ws')(app); 
 
app.get('/', function (req, res) { 
    res.send('Nginx demo!!!'); 
}); 
 
app.ws('/echo', function(ws, req) { 
    ws.on('message', function(msg) { 
        ws.send(msg); 
    }); 
}); 
 
app.listen(3000);
