Primary Skills

The skills listed below are essential for becoming a MERN Stack Developer and excelling in the role.

‍

MERN Stack

It is a popular set of technologies, named MongoDB, Express.js, React, and Node.js. MERN Stack Developers utilize these technologies to create data-driven web applications that can handle a high volume of users.

JavaScript

It is the core of both frontend and backend development using React and Node.js. Therefore, MERN stack developers must possess proficiency in ES6+ features, asynchronous programming, and functional programming concepts to effectively build applications.

JavaScript Object model

It encompasses both the manipulation of the Document Object Model (DOM) which aids in web page interactivity and JavaScript Object Notation (JSON) for data exchange and storage. Thus, it requires MERN stack developer to have the ability to use DOM to create interactive structures and content of the web pages.

React

This popular JavaScript library aids in building effective and interactive user interfaces. It also consists of various components that help developers in creating a rich and responsive front end.

Node.js

MERN stack developers utilize this server-side JavaScript runtime to build scalable and efficient server applications.

Express.js

It is a backend web application framework that enables developers to create RESTful APIs and handle server-side logic.

MongoDB

This NoSQL database aids MERN stack developers to store and retrieve data in a JSON-like format. It requires them to possess an understanding of database design, querying, and integration with Node.js.

HTML and CSS

HTML is a markup language and CSS is a styling language that complements HTML to design web pages. MERN developers need to have understanding of both as it enables them to design and maintain the original meaning while providing a bit more specific role.

RESTful APIs

It acts as an interactive interface that establishes a safe & secure connection between two computers. Developers utilize them to initiate HTTP requests, share data in the form of JavaScript Object Notation (JSON), and then subsequently parse and utilize this data.

GraphQL

It is a server-side runtime for APIs as well as a query language. By integrating GraphQL, MERN stack developers get to effectively fetch data from APIs.

Version Control

It helps to accurately track and manage changes to the source code of the software applications. One of the most commonly used version control systems that MERN stack developers are required to be aware of is Git.

Deployment and HostingIt

requires a MERN Stack developer to possess a good understanding of cloud platforms like Netlify, Vercel, Heroku or AWS for successful application deployment.

Security Best Practices

It refers to a collection of policies, ideas, and tactics that emphasize the integration of security measures and concerns across the whole software development and operations lifecycle.

LESS/SASS

MERN stack developers should have a good understanding of Syntactically Awesome Stylesheets (SASS) and Leaner CSS (LESS) as it helps them make CSS more maintainable and extendable.
