Declaring Routes in a Module

The first step to organizing our routes is getting them all into their own module. There are multiple ways to do this. One approach is to make your module a function that returns an array of objects containing “method” and “handler” properties. Then you could define the routes in your application file thusly:

var routes = require('./routes.js')(); routes.forEach(function(route){ app[route.method](route.handler); })

This method has its advantages, and could be well suited to storing our routes dynamically, such as in a database or a JSON file. However, if you don’t need that functionality, I recommend passing the app instance to the module, and letting it add the routes. That’s the approach we’ll take for our example. Create a file called routes.js and move all of our existing routes into it:
