Question

I\'m trying to create a really simple node API using express.js 4 but I need a few \'realtime\' events for which I added socket.io. I\'m fairly new to both so I\'m likely m

I've modified your files a little bit, may you check if it works?

You can pass the io you've defined to your routes like below;

require('./routes/api')(app,io); 

I didn't test the Socket.IO parts but there is no syntax error and routes also working.

server.js file:

var express = require('express');
var app = express();
var path = require('path');
var logger = require('morgan');

var io = require('socket.io').listen(app.listen(3000));

app.use(logger('dev'));
app.use(express.static(path.join(__dirname, 'public')));

io.sockets.on('connection', function (socket) {
    console.log('client connect');
    socket.on('echo', function (data) {
    io.sockets.emit('message', data);
 });
});

require('./routes/api')(app,io); 

console.log("Server listening at port 3000");

api.js:

module.exports = function(app,io) {
app.put('/foo', function(req, res) {

    /* 

      do stuff to update the foo resource 

      ...

     */


    // now broadcast the updated foo..

    console.log("PUT OK!");

    io.sockets.emit('update'); // how?
    res.json({result: "update sent over IO"});

});
}
