POST data through socket.io in app.js

Question

I would like to:

• Retrieve data entered from input forms.
• send data through socket.io and send console log done
• get data on express app.js
• paste the data into the mongodb database using mongoose.

I understand that it is publishing messages, but not sure how to send data. thank you in advance

my app.js is configured as follows:

//app.js config ... var socket = io.listen(server); socket.on('connection', function(socket) { console.log('socket.io connected'); }); app.post('/go', function(req, res) { socket.on('data', function(data) { new Order({ routeFrom : data.routeFrom, routeTo : data.routeTo, leaving: data.leaving }).save(function(err, docs) { if(err) { console.log("error"); } res.json(data); }); socket.emit('callback', {done: 'Done'}); }); }); 

my index.ejs file:

  <script src="/socket.io/socket.io.js"></script> 

  var socket = io.connect('http://localhost:3000'); $('#send').on('click', function() { $.post('/go', { socket.emit('data', { routeFrom: $('#rf').val(), routeTo: $('#rt').val(), leaving: $('#l').val() }); }); socket.on('callback', function(data) { console.log(data); }); });

You do not need POST at all.

I would do on the client side:

 var socket = io.connect('http://localhost:3000'); $('#send').on('click', function(event) { event.preventDefault(); socket.emit('data', { routeFrom: $('#rf').val(), routeTo: $('#rt').val(), leaving: $('#l').val() }); }); socket.on('callback', function(data) { console.log(data.done); // Print the data.data somewhere... }); 

And on the server side:

 //app.js config ... var socket = io.listen(server); socket.on('connection', function(socket) { console.log('socket.io connected'); }); socket.on('data', function(data) { new Order({ routeFrom : data.routeFrom, routeTo : data.routeTo, leaving: data.leaving }).save(function(err, docs) { if(err) { return console.log("error"); } socket.emit('callback', {done: 'Done', data: data}); }); });
