NodeJs : Modularizing routes with ExpressJs

In a previous post I described how to do routing in a NodeJs app with ExpressJs. When the application gets bigger separate routes from our main code is always a good practice. Lets take a look at, how to separate the routes from our main code.

1. First step is create a separate folder for routes and lets name it as "routes".
2. Next create index.js file in "routes" directory
   After this step the project structure will look like this.
   

   
   |--routes
   |  |-index.js
   |--views
   |  |-default.js 
   |--app.js
   

   
   
3. Export routes in index.js file.
   

   
   exports.index = function(req,res){
       res.render('default',{title:"Home"});
   }
   

   
   
4. Require the routes folder in app.js file
   

   
   var routes = require('./routes');
   

5. Provide methods in index.js file to get method of Express when cofiguring routes
   

   
   app.get('/',routes.index);

In this way we can modularize our routes in node.js app and we can have a clean and understandable code.
