MERN is a full form for Mongo DB, Express DB, React JS, and Node JS, these are all front-end programming languages with one thing in common, they are all based on JavaScript which is used to make very intricate and feature-filled websites with elaborate visual effects. MERN is a combination of all the above languages that are mentioned. However, Express DB and Mongo DB are back-end programming languages. Therefore, MERN is a combination of all languages that enable great development for websites and web applications with both front-end and back-end designing.
MERN is designed to have great scalability (MongoDB), variable speed (Express JS), high degree of UI layer abstraction (React JS), faster code deployment , code organization tools and finally best in class UI rendering and performance (Angular).
Components:
1. MongoDB: MongoDB is an open source, cross platform, NoSql, DBMS. It is a document-oriented database, which means that data is saved using collections and documents, instead of tables and rows, like in a relational database. This makes possible easier and faster data integration within applications. MongoDB stores the data in binary JSON format that allows the fast exchange of data between client and server. MongoDB can be used for the storage of large volumes of data, which makes it highly scalable.
2. Express JS: Express JS is a modular, lightweight framework of the Node JS, that helps in building web applications. It is a server side, back-end, JavaScript based framework, that is designed to write simplified, fast and secure applications. It can be assumed that Express JS, runs on top of the Node JS, managing the server and its routes.
3. React JS: React JS is an open-source JavaScript library used to build user interfaces, typically for single page applications. React JS enables developers to modify/edit and refresh the page to view the changes without having to restart or reload the page. React JS offers the facility of code reusability on multiple platforms. It is fast and scalable.
4. Node JS: Node JS is an open-source, cross platform, JavaScript runtime environment. It is designed to run the JavaScript code outside the browser, on the server side. Node JS accesses the Node Package Manager (NPM), that hosts a large number of private and public packages, and is as well utilized for publishing Node JS projects. It is based on the event-driven, non-blocking I/O model.
Conclusion:
MERN stack is used for crafting web pages that fall in the premium category. Like MEAN stack, it also has comprised of four frameworks, namely MongoDB, Express.js, React, and Node.js. For developing web apps, it makes use of libraries, databases, and frameworks. MERN stack ensures a very smooth development process. The MERN stack is becoming very popular in the development market.
MERN Stack brings in the best of all the programming languages and it has been developed with the entire front-end and back-end community’s new demands in mind and is hence being adopted by many development houses at an alarmingly high rate.
That’s it for today folks! Topic for tomorrow: What is LAMP stack?
