MongoDB is a NoSQL database that provides flexible data storage layers, and Node.js keeps your server running continuously. It harnesses the potential of faster computer network. Express.js standardizes the web application development and Angular.js allows interactive gestures on web applications. Together, they form the MEAN stack.
Developers, who realized LAMP stack (Linux, Apache, MySQL, and PHP) is not flexible enough to serve their purposes, are gradually making a move towards MEAN stacks. And it’s a high time you should too. There are many reason you should.
The MEAN stack offers flexibility and simplicity that powerful LAMP doesn’t. Not so long time ago, web development meant WordPress. Web development has evolved since. With so many technologies, the problem is which technology should I adopt for the next project?
Let’s take AngularJS, for instance, a web development framework backed by Google, overcomes the limitation of HTML in single page application development. In addition, there are few frameworks that are suitable for the development of small applications.
|MEAN Stack||LAMP Stack|
|Operating System||Cross-platform||Linux OS only|
|Database||MongoDB, a ‘non-relational’ database||MySQL, a ‘relational’ database|
|Structure||Slower & limited due to its blocking structure||faster & scalable due to its non-blocking structure.|
|Technologies||MongoDB, Express.js, AngularJS, Node.js||Linux, Apache, MySQL, PHP|
|Mainstream Backers||Google, IBM, Samsung||Oracle, Zend, Linux Foundation|
The MEAN stack
Developers looking to host maximum user engagement on their web app choose the most feasible technologies and frameworks. There is a long list of technologies and MEAN stack is recipe to modern web applications. Introduced in 2014, MEAN has transformed the way the web development progresses. As mentioned above, four components in MEAN Stack are the following:
Express.js, a back-end web application framework running on top of Node.js
browser, allowing your application UI to be dynamic

The database system: MongoDB
MongoDB has the best of the both worlds fast, scalable key-value stores of NoSQL and rich functionality of relational databases. Unlike relational database MongoDB stores BSON documents inside collections with active schemas.
While relational databases like MySQL stores data in specific rows and columns, MongoDB's document data model stores data regardless of its structure and doesn’t void existing authentication rules, data access, and indexing functionality. You can actively adjust the schema without interruption – trivial for swiftly scaling web applications.
The backend web framework: Express.js
Express handles allocation of requests to different parts of an application (or to various apps running in the same environment).
Express executes the part of a web app's code that is responsible for business logic and returns an HTML file to be compiled by a web browser. However, Express, mostly gives a RESTful APIs that the front-end can access with a single line of code.
The frontend framework: AngularJS

Angular application code can compile in the back-end server rather than in the frontend browser, or as a native desktop or mobile app.
The backend runtime environment: Node.jsm
Node.js is asynchronous and event-driven. That is, an application doesn’t poll an acknowledgement to a request. It resumes other tasks in the meanwhile. Upon completion, a callback request informs the application and it can start other tasks for optimal resource utilization, which enables many parallel operations while scaling applications. MongoDB can work asynchronously too and, thus, works well with Node.js applications.
If you are still not confident about MEAN stack, we will take you through why you should be using MEAN stack for your next web development project.
Cost-effective while fast and scalable
Advantages of Node.js
Node.js is a crucial part of MEAN stack and is a very scalable and robust framework. Node.js is the runtime environment and is comply with non-blocking input and output. Thus, a new query is handled efficiently. In LAMP stack, the client had to direct a request for the query to be created. With Node.js, this all happens automatically.
The MongoDB Advantage
MongoDB is the database web developers need while managing huge amount of data. The whole thing works like OOPs and makes way for easy, effective handling.
Open-source—edit the source, compile, and install
Technologies that bring us MEAN stack are all open-source. That is, developers get access to the codes of each technology and can modify the core to meet their individual needs. The technologies doesn’t cost a buck to use and distribute, which means you not only can use it for personal use but also can install them on your employees personal workspaces.
Good Community Support
A large community of individual and corporate contributors and sponsors back the technologies in the MEAN stack and the MEAN stack itself. There are programmers, experts, everyday people who have worked on one of the technologies in the past. When you are unable to debug a nasty piece of code, they are the people you seek help from.
