Why learn MEAN Stack?

Sharing is caring!

“Web development is a fast-paced and diverse environment. It may be hard to navigate in such a variety of frameworks and technologies, and choosing the technology that suits you best may also prove to be challenging.”

Having built dozens of successful web applications for startups and businesses worldwide, we at Eastern Peak know the ins and outs of every web development technology out there.

What is it, and why choose MEAN STACK for your next project?


The term MEAN stack refers to a collection of JavaScript based technologies used to develop web applications. MEAN is an acronym for MongoDB, ExpressJS, AngularJS and Node.js. From client to server to database, MEAN is full stack JavaScript.

The main reason for choosing the MEAN stack over others is because of the use of a common language for both client-side and server-side. Since, all these technologies are written in JavaScript, your web development process becomes neat. Node.js is a platform that brought JavaScript implementation on the server-side. With Angular.js, using JavaScript on the front-end, it becomes easier to reuse code from back-end to front-end.

  • M: MongoDB: It is the open-source, free, cross-platform database for JavaScript. It uses JSON document-oriented style for all the data representation. The logic behind choosing MongoDB is that it restricts us to just one language-JavaScript for the whole application development.
  • E: ExpressJS : Express.js is one of the most vital tools for developing effective mobile and web applications. It is the minimal framework for web development using Node.js. However, its functions are pretty massive. It is possible to build a whole website just using Node.js and Express.js. The combination enables us to build software on the server-side in which Node.js is essential, while Express.js helps to publish the app on our website. It offers a diverse variety of features like database integration, simplified multiple routing, template engines.
  • A: AngularJS: It is a front-end JS framework that extends HTML with few new attributes. It is used in developing client-side applications with modular code and a data binding User Interface. It is absolutely perfect for developing (SPAs) Single Page Applications. It is easy to learn.
  • N: Node.js : Node.js is a very powerful, open source, cross-platform JavaScript-based run-time framework built on Google Chrome’s JSV8 engine. Being a completely free platform, it is used by thousands and thousands of developers around the world. It combines with ExpressJS for the application development.
Why we need MEAN Stack?
  • You can’t do much on the web without it, so people are increasingly going straight to Javascript and Skipping Ruby, Python and PHP.
  • Javascript boasts the most active developer community.
  • Third reason you should learn Javascript right out of the gate : EMPLOYABILITY — Employers aren’t just starved for engineers familiar specific Javascript — based technologies. And those technologies happen to be the ones that compose the MEAN STACK — MongoDB, Express.js, Angular.js and Node.js.

WOW facts about MEAN STACK:

  • It’s been used by PayPal, Uber, Linkedin among many other
  • Angular.js — The ‘A’ in MEAN Stack. Google (and by extension YouTube) have poured a ton of money and engineering talent into improving Angular.js.
  • As noted above, Each of the MEAN Stack’s individual components is emerging as the winner of it’s respective category.

Features of MEAN Stack

MEAN makes code isomorphic

The simplicity doesn’t stop with using JavaScript on the server. By going MEAN, you can enjoy that same JavaScript on the client, too, leaving behind the LAMP stack’s client/server schizophrenia. If you write code for Node and decide it’s better placed in AngularJS, you can move it over with ease, and it’s almost certain to run the same way. This flexibility makes programming MEAN-based apps significantly easier.

JSON everywhere

MEAN uses the same JSON format for data everywhere, which makes it simpler and saves time reformatting as it passes through each layer. Plus, JSON’s ubiquity through the MEAN stack makes working with external APIs that much easier: GET, manipulate, present, POST, and store all with one format.AngularJS and MongoDB both speak JSON, as do Node.js and Express.js.

Node.js is superfast

Apache was great, but these days, Node.js is often flat-out faster. These days, especially among impatient mobile device users, shaving even milliseconds off your app’s performance is important and Node.js can do that, while offering a Turing-complete mechanism for reprogramming it.

MongoDB is built for the cloud

If your Web app plans include making good on the pennies-per-CPU promise of the cloud, the MEAN stack offers a compelling database layer in MongoDB. This modern database comes equipped with automatic sharding and full cluster support, right out of the box. Plug in MongoDB and it spreads across your cluster of servers to offer failover support and automatic replication. Given the ease with which apps can be developed, tested, and hosted in the cloud, there’s little reason not to consider MongoDB for your next project.


There are many well-known organizations using Node.js in production, including PayPal, LinkedIn, Netflix, and the New York Times. Some examples of application types which can benefit from using Node are REST APIs, Chat applications and Real-Time Tracking applications .

This new approach requires the use of backend applications which are very fast, scalable and easy to deploy & maintenance. All major companies have started to migrate their applications to Node.js and others are building applications from scratch using the MEAN stack technology. PayPal, Dow Jones and Uber have already placed a business Node.js solutions into production. Yahoo, HP and many others have planned their next generation products on this MEAN stack platform.

Best Use Cases

The MEAN stack is perfect for building all kinds of applications, from dynamic single-page applications to complex enterprise and social media apps.

For example, it can be used in different types of apps:

  • Complimentary business apps.
  • Enterprise apps.
  • Web apps using big data.
  • Multimedia streaming apps.
  • Real-time applications (social networks, chats, and forums).

While it is difficult to say which companies use the MEAN.JS stack in its entirety, Node.js has gained wide adoption among top-tier companies including PayPal, LinkedIn, Netflix, Walmart, and Uber.
