List of Things that MERN Stack Developers Should Look For

MERN Stack is a Javascript stack for deploying full-stack web applications more easily and quickly. MongoDB, Express, React, and Node.js are the four technologies that make up the MERN Stack. It’s geared to make the development process go more smoothly and efficiently. Each of these four strong technologies provides an end-to-end framework for MERN developers to work in, and they all play an important role in web application development. Any person who wishes to indulge in MERN stack development should significantly consider the four technologies. 

MongoDB: Cross-platform Document-Oriented Database 

MongoDB is a NoSQL database in which each record is a document made up of key-value pairs that look like JSON (JavaScript Object Notation) objects. MongoDB is adaptable, allowing users to design schemas, databases, and tables, among other things. MongoDB’s fundamental unit is documents that are identified by a primary key. Users can also use Mongo shell once MongoDB has been installed. Mongo shell has a JavaScript interface that allows users to communicate and perform actions (eg: querying, updating records, deleting records).

Why use MongoDB? 

  • Fast – Because it’s a document-oriented database, indexing documents is simple. As a result, a quicker reaction.
  • Scalability – Large amounts of data may be managed by splitting them among several computers.
  • Uses JavaScript- MongoDB makes use of JavaScript, which is its main benefit.
  • Schema Less – Separate document for any sort of data.
  • Data store in JSON form:
  1. Objects, Object Members, Arrays, Values, and Strings
  2. JSON syntax is very simple to use.
  3. JSON is supported by a wide range of browsers.
  4. Data sharing: Data of any size and type (video, audio) can be simply shared.
  • MongoDB is really easy to set up.
  • MongoDB features a flexible document model (tables, schemas, columns, and SQL) that is quicker and easier to use.

Express: Back-End Framework

Express is a framework for Node.js. Instead of writing the code in Node.js and building a slew of Node modules, Express makes writing the back-end code more simpler and easier. Express aids with the creation of excellent web apps and APIs. Many middlewares are supported by Express, making code shorter and easier to develop.

Why use Express? 

  • Asynchronous and Single-threaded.
  • Efficient, fast & scalable
  • Has the biggest community for Node.js
  • Express promotes code reusability with its built-in router.
  • Robust API

React: Front-End Library 

React  is a JavaScript library for creating user interfaces. Because of its capacity to manage quickly changing data, React is employed in the development of single-page apps and mobile applications. Users may write with JavaScript and create UI components with React.

Why use React? 

  • Virtual DOM- A virtual DOM object is a virtual version of a DOM object. The virtual DOM is a replica of the original DOM. The differences between the original DOM and the virtual DOM are compared, and adjustments are applied to the original DOM as needed.
  • JSX – an abbreviation for JavaScript XML. It’s a JavaScript Extension for HTML/XML that’s utilized in React. Makes writing React components easier and more straightforward.
  • Components- Components are supported by ReactJS. Components are the UI’s building blocks, each with its own logic and contribution to the overall UI. These elements also aid code reuse and make the whole web application more understandable.
  • High performance- It is considerably quicker than the rest of the frameworks because of features like Virtual DOM, JSX, and Components.
  • Developing Android/Ios Apps- With React Native, you can simply create Android and iOS apps with just JavaScript and ReactJS skills.
  • To get started with your react application, use npm or yarn to install “create-react-app.”

Node.js: JS Runtime Environment 

The JavaScript Environment provided by Node.js allows users to run their code on the server (outside the browser). The user may pick from thousands of free packages (node modules) to download using the Node Pack Manager, or npm.

Why use Node.JS?

  • Open-source JavaScript Runtime Environment
  • Single threading – Follows a single-threaded model.
  • Data Streaming
  • Fast – Built on Google Chrome’s JavaScript Engine, Node.js has a fast code execution.
  • Highly Scalable

MERN stack type is useful for creating databases; for example, web-based historical archives, which can conveniently arrange and store hundreds of historical documents from various times in history. MERN Stacks is easier to learn from the perspective of a developer because it is written in a single language from the backend to the frontend. In case you have a problem with this technology, you may consult Sonatafy, a reputable IT company with highly trained experts.
