Web Application Development With MERN Stack

Agile practices in software development are evolving at a rapid pace across the globe. Enterprises are leveraging the best technological stacks today to unlock the full potential of agile development and reap its maximum benefits to ultimately boost ROI.

MERN Stack is one such popular technology stack used today for faster application development worldwide. The core objective of this stack is to ONLY use JavaScript for application development. That is because all the four technologies housed in the MERN stack are JS-based. Hence, if you are well-versed with JavaScript and JSON, you can easily operate full stack including database, frontend, and backend.

In this post, we are going to see why you need a full stack web development Bootcamp with MERN stack projects:

What is a MERN Stack?

MERN is a JavaScript-based Stack used to deploy full-stack web applications faster and in a seamless manner. MERN stack is made up of four technologies viz. MongoDB, Express, React, and Node.js. All of these four technologies are extremely powerful and offer a robust end-to-end framework to help developers build and deploy dynamic web apps. 

Since it uses JavaScript on the frontend as well as the backend, it provides high flexibility to develop a wide range of web application projects.

By the same token, the MEAN stack is also quite popular amongst developers. It stands for MongoDB, Express, Angular.js, and Node.js. If you’re wondering, full stack vs. MERN stack vs. MEAN stack– which one is ideal for your development project, you need to consider the following points

  • What would be the total development cost?
  • Does it cater to your project requirements and goals?
  • Does it allow agile development?
  • Will it help you go above and beyond project requirements to attract a large audience?
  • Do you have teams with optimal experience and expertise in the chosen stack? 
  • Do you have a development team that is flexible and scalable?

What is Full Stack Development?

Full Stack Technology means a set of programming languages, tools, libraries, frameworks, UX/UI solutions, and patterns that a full stack developer uses to work on the frontend as well as the backend of an application.

The term “Full Stack” development refers to developers working on the “Full Stack” of a website or application including the frontend, backend languages, servers, APIs, database, and version control systems.

A full-stack developer manages the structure of project designs. As per the project requirements, the developer may swap their roles and responsibilities. Likewise, MERN stack developers and MEAN stack developers are experts in detecting errors, and thereby offering ideal solutions for various web architectures. Web Application Development With MERN Stack

Main Components of a MERN Stack:

  • MongoDB: A Cross-platform Database 

MongoDB is a popular open-source, document-oriented NoSQL database where every single record is in the form of a document housing key-value pairs, just like JSON objects. It is a highly flexible database that allows you to seamlessly create databases, schema, tables, and so much more. It helps you store, manage and retrieve document-oriented information.

MongoDB is best-suited for those who have to manage large sets of distributed data.

Why choose MongoDB?

  • Scalable: It divides large sets of data into multiple machines making it easier to manage.
  • Faster: Since it is a document-oriented database, it becomes a lot easier to index documents, thereby resulting in faster responses. 
  • Schema Less: It makes no changes to your data, as it stores each item separately in its own document with a partial schema without touching your raw information.
  • JavaScript-based: The biggest advantage of using MongoDB is that it leverages JavaScript. Information is stored in the JSON form (objects, arrays, object members, values, and strings) and its syntax is a breeze to use. Moreover, JSON has extensive browser compatibility and allows easy sharing of data, be it any type and size.
  1. Express: Backend Framework:

Express is a Node.js framework that makes it very easy for developers to write backend code. You can design intuitive APIs and web applications with Express. It supports a wide range of middleware to help you write short and easy codes.

Why Choose Express?

  • It has large community support for Node.js
  • Faster, scalable framework that boosts efficiency
  • Single-threaded and Asynchronous
  • Uses robust API
  • Built-in router allows you to reuse code
  1. React: Frontend Library

React is a JavaScript library that you can leverage to build seamless UIs (User Interfaces). React is generally used to build and develop single-page applications as it is capable of handling fast-changing data. It helps you code in JavaScript and build amazing UI elements. 

Why choose React?

  • Components: React.js supports ‘Components’- the building blocks of a User Interface. Every single component has a logic that eventually helps it contribute to the overall UI. Components promote code reusability and make it easier for you to understand a web application.
  • High-performing: React comprises features like JSX, Components, Virtual DOM, etc. which makes it a high-performing framework. 
  • Virtual DOM: A virtual DOM object is nothing but a copy of the root DOM. Any changes made to the web application will result in the UI re-rendering the virtual DOM. These changes are then compared and accordingly, the root DOM is then modified.
  • JSX: React supports JSX which is an acronym for JavaScript XML. It is an HTML/XML JavaScript Extension that makes it easier for you to write React components.
  • Build iOS/Android applications: One can easily code and develop iOS/Android applications using React Native if they have enough technical knowledge of React.JS and JavaScript.

Node.JS: JavaScript Runtime Environment

Node.js is a cross-platform, open-source backend JavaScript Runtime Environment. It is built upon the V8 engine and runs JavaScript code on the server (outside your browser). It is mainly useful in building scalable network applications, backend API services, and traditional websites. As it is single-threaded, Node.js is best suitable for event-driven, non-blocking servers.

There are thousands of node modules available for FREE download via npm (node pack manager).

Why choose Node.JS?

  • Open-source, cross-platform JavaScript Runtime Environment
  • Highly scalable 
  • Single-threaded with Event Loop Model
  • Faster code execution as it is built upon Google Chrome’s V8 JavaScript Engine 
  • Data Streaming

Many biggies in the industry such as Netflix, WhatsApp, Instagram, Facebook, and Dropbox use mobile applications built with the popular MERN stack.

Why Choose MERN Stack for Web Application Development?

MERN and MEAN Stacks are somewhat similar, but there are a few key points that make the MERN stack stand out from the rest, such as:

  • Document-oriented data management
  • Supports Sharing
  • Uses robust and flexible technology to manage database
  • Single Master Replication

MERN is a robust stack for enterprises wanting to build high-quality web applications. That is because the MERN stack leverages high-performing and flexible technology that allows faster and easier web app development.

The entire MERN stack makes use of REST API, including the database, frontend as well as backend. It can act as a middleware and allow you to reuse code to build other applications.
