Error: The function Undefined is not recognized by express.io

Struggling to configure express.io with individual files for each route? Check out the examples provided.

Currently, I have a typical Express setup that I want to transition to express.io:

Project
    app.js
    routes
       servepage.js
    Views
       servepage.jade
    public
       main.js   <-- client side javascript

In the example they provide for routing, the code is placed in app.js like so:

var express = require('express.io');
  .... lots of Express routes omitted
app.io.route('ready', function(req) {
    req.io.emit('talk', {
        message: 'io event from an io route on the server'
    })
})

I tried moving just the route definition to app.js:

app.io.route('ready', servepage);

But this resulted in the error:

TypeError: undefined is not a function

How can I set up the application using more than just app.js? What could be causing this error?

EDIT: In servepage.js, I am including:

var express = require('express');

Rather than:

var express = require('express.io');

To avoid errors.

Answer №1

It appears that you forgot to include the require statement for the servepage.js file

The code in servepage.js should look like this:

module.exports = function(){ ... };

In your app.js file, make sure to include the following code:

var servepage = require("./routes/servepage.js");
app.io.route('ready', servepage);
