Everything to Know about MEAN Stack

With the increase in the number of internet users, the demand for a rich user experience has also increased considerably. Whether the website is displayed over the desktop or a mobile app, performance and consistency in interactivity are essential to increase the audience base. However, the need to offer greater functionality along with user-friendly layout puts the developers under immense stress. In this regard, MEAN stack has gained prominence in the past few years.

What is MEAN Stack?

MEAN Stack

MEAN contains a defined set of Open Source elements that offer an end-to-end framework that helps in building dynamic web applications. The stack sets up a framework from the front end to back end. It offers uniformity of coding since developers can stick to JavaScript for writing the code. Using the same language at all stages considerably reduces the complexity of the code.

Collectively, the MEAN stack forms a full-stack development language that follows a top (the browser on which the code is run) to bottom (database) approach.

Components of MEAN

The acronym MEAN stands for:

  •    MongoDB – database server
  •    Express.js – server-end JavaScript Framework
  •    Angular 2 – client-end JavaScript Framework
  •    Node.js – JavaScript Runtime

MongoDB

MongoDB makes use of a schema-less format. It makes the design more scalable and flexible. It is a document database and does not rely on the software design. Through the data transfer using JSON format, transferring data would be economical and easy.

Express.js

Express is an extremely popular web application framework that is compatible with Node.js. It has a minimal design and offers programmable web server, giving it the qualities of high performance and lightweight architecture. Express effectively handles website requests and their corresponding responses.

Angular 2

Formerly known as AngularJS, Angular is used to develop the front end layout of the MEAN application. It runs the JavaScript (TypeScript) code to create a reactive and interactive user interface. With Angular, developers can focus more on the application design than the code.

Node.js

Node.js is the JavaScript runtime that is responsible for running the server-end (back end) of the MEAN application. It helps in faster execution of the application and compiles the JavaScript to native machine language prior to code execution.

Advantages of MEAN Stack

MEAN stack is slowly replacing LAMP [Linux (Server), Apache (web server), MySQL (Database) and PHP (backend)], this is due to the following advantages that MEAN possesses:

  •    MongoDB is a document database. It does not require the setting up of predefined schemas or rules to establish any kind of field regulations. This makes adding, deleting, and editing data not only faster but also easier.
  •    MEAN makes use of JavaScript consistently, which reduces the need for multiple languages to implement the framework. Due to the language uniformity, pages will load faster and more smoothly.
  •    Any operating system that supports Node.js will also support MEAN stack, which means that MEAN is already compatible with prominent operating systems such as MS Windows, Linux, and MAC OS.
  •    It is an open source program.
  •    MEAN stack allows efficient allocation of resources due to which there will be a visible increase in efficiency, productivity, and will enhance user experience.

Conclusion

Considering the advantages of MEAN stack, if you are a developer looking to build a fast, scalable, and robust application – then MEAN stack is the medium to execute precisely that. It has developed into a reliable stack as it offers an easier way to build and develop your apps. New JavaScript frameworks are added to MEAN stack periodically, which keep it relevant and up to date. Upgrading your app will become easier with MEAN stack, and it definitely features prominently in the future of app and website development.
