My new favorite web application development platform is the MEAN stack: MongoDB, Express, AngularJS, and Node.js.

I unknowingly came across it when I began working on a web application prototype at work. While I was familiar with MongoDB (our team used it in a previous prototype), I was really itching to learn Node.js… so I took the plunge and began poring over tutorials. Many of the examples repeatedly mentioned Express as a handy Node.js web application framework, so it was an easy decision to include it as part of my toolset. My biggest challenge, however, was organizing the client-side code. I have used Backbone.js before, but I wasn’t fully satisfied with it. A colleague of mine then mentioned an emerging client-side MVC framework from Google called AngularJS and encouraged me to check it out. The rest, I guess you can say, is history.

Well, what’s so great about MEAN? The key advantage is using one language, JavaScript, across the whole stack. First, it’s a lot easier to move back and forth between server-side and client-side code since they’re written in the same language. Second, with MongoDB, the data is in a JSON document structure, which makes passing data between server and client trivial. By using the same language and having a consistent data structure across the whole stack, the web development process is a lot more seamless.

To help others get started with MEAN, I have created a Vagrant environment that can be found here.
