How to use sock.io within mini-routes?

[Lasse Karagiannis]

Hi, I want to emit a socket.io event within mini routes. How do I accomplish this?
In my server,js I have:

var http = require("http");

var server = http.createServer(app);

var io = require("socket.io").listen(server);

app.set("socketio",io);

app.set("server", server);

app.get("server").listen(port, function() {

    console.log("Express started on https://localhost:" + port);

    console.log("Press Ctrl-C to terminate...");

});

app.use("/", require("./routes/home.js"));

app.use("/", require("./routes/todo.js"));

});

// In this examle we just have static files

app.use(express.static(__dirname + '/public'));

// This is called every time a client is conneting

// the socket is for the client that connects

io.on('connection', function (socket) {

    // When a client call for login

    socket.on("login", function(data) {

        // Save the username in the socket object

        socket.username = data.username;

        var welcomeMessage = "Welcome to the chat " + socket.username;

        // This is sent to the one client that connected

        socket.emit("welcome", {message: welcomeMessage});

        // This is broadcast to all connected users (except the client that send this)

        socket.broadcast.emit("newUser", {message: socket.username + " has joined the chat!"});

    });

    // When a client sends a new message

    socket.on('chatMessage', function (data) {

        // Tell all clients there is a new message - Send back to the one that wrote it

        io.emit('chatMessage', {

            message: data.messageText,

            user: socket.username

        });

    });

    // Called when a socket/client is disconnecting from the WS

    socket.on('disconnect', function () {

        // echo globally that this client has left

        io.emit('userLeft', {

            user: socket.username

        });

    });

});

Then one of the mini-routes look like this:

"use strict"

// Use the express.Router class to create modular, mountable route handlers.

let router = require("express").Router();

// this will trigger on the root url (/)

router.route("/")

    .get(function(request, response) {

      

     Here I want to do, something like
         var socketio = request.app.get("socketio");

         socketio.emit("time", Date.now());

      // middleware that is specific to this router

        // render the view for the home

        response.render("home/index"); /

});

// Exports

module.exports = router;
