Ultimate Guide to Become MERN Stack Developer

Want to become a full-stack developer? You would find various types of full stack developers out there but among those, MERN stack developers are the most popular ones. Let’s make it simple. A full-stack developer is someone who can create a complete web application using both front-end and back-end development skills. And what we call a MERN stack developer is someone who can develop the same web application using MongoDB, Express, React and Node. MERN stack developers are proficient in JavaScript; they use HTML, CSS and JavaScript for front-end operations and JavaScript with Node.js for back-end operations.

If you are among those who wish to become a MERN Stack developer in Nepal, this blog is for you. Here we have come up with the ultimate guide to become a MERN stack developer in Nepal. Stay tuned.

What is MERN Stack?

The MERN stack is the most popular stacks used to create dynamic web interfaces. It’s composed of MongoDB, Express.js, React, and Node.js. The MERN stack is majorly used in social media platforms and news aggregation applications. Prominent companies like Netflix and Uber has been using MERN stack in their web development.

React is the most popular JavaScript library and it is primarily used to build single-page applications and mobile applications. React makes it simple to create and manage the user interface (UI) of an application. 

When put together with MongoDB, Express.js, and Node.js, React gives you a JavaScript-based, developer-friendly and cost-effective tech stack.

Steps to become a MERN Stack Developer

As the MERN stack is composed of so many different components, at times, it becomes overwhelming and frustrating to decide what exactly needs to be done to become a MERN Stack developer. Below are 5 essential steps you can follow to become a MERN Stack Developer in Nepal.

  1. Learn Front-End Programming Languages

    The journey to becoming a MERN Developer begins with the understanding of three basic programming languages: HTML, CSS, and JavaScript. 

    HTML: Hypertext Markup Language (HTML) is the standard front-end language used to create input content that will be displayed on a website. HTML instructs what and how to display on the page. With HTML, you get to manage the fonts, colors, headings, title, graphics and the layout of the website.

    CSS: Cascading Style Sheets (CSS) is another front-end language but this is used to alter the appearance of the website including its text, color and buttons.

    JavaScript: JavaScript is a programming language that is used to control the behavior of web pages and make them dynamic, interactive and engaging for the user.

    You can learn these programming languages through online guides, video tutorials or by joining a web development course in Nepal.

  2. Learn Using Front End Tools

    Now that you have the basic knowledge of HTML, CSS, and JavaScript, you can proceed with the next step i.e. to learn how to use front-end tools that are essential to speed up your programming. There are many front-end tools out there and different front-end tools are used to do different types of tasks. One of them is Git.

    Git is an open-source version control system that is used to manage the changes made to the codes. It allows web developers to return the document to a previous state whenever an error is made. There are many other options to manage these changes but developers prefer Git as it is fast, scalable, decentralized and free.

  3. Understand the Basics of Website Design

    Once you have learned the technical side of front-end web development, you are now ready to explore the design aspect of website development. Understanding the basic principles of designing prototypes, will help you make an attractive and engaging website, as you can play with various colors, fonts, and layouts on the website. It also allows you to be dependent on web designers.

  4. Learn React

    Now it’s the time to take the big step and it is to learn how to use React. React is the open-source front-end library that is used to create the user interface of single-page applications and mobile applications. You can self-learn React, either through online guides or by joining a React developer course in Nepal. You can take React developer training in Nepal at Tech Axis as we provide the best React training in Nepal.

  5. Learn Back End Components of MERN Stack

    Now that you have mastered the front end, you can now move on to the MERN stack's back end components. MERN stack back-end components include Node.js, Express.js, and MongoDB. Let’s look at each of the components and what they do.


    Node.js is an open-source and cross-platform JavaScript runtime environment (RTE) that runs Chrome’s V8 engine for back-end development. It makes it possible for developers to create fast and scalable server-side web applications easily. As you start working with Node.js, it’s recommended to learn how to use Node Package Manager (npm) as it simplifies managing multiple code versions.


    When Node.js performs an I/O operation such as reading from the network or accessing a database, instead of wasting CPU cycles waiting, it resumes the operations when the response comes back. Node.js allows developers to handle thousands of concurrent connections with a single server without the burden of managing thread concurrency.


    Express.js is a back-end framework that works inside Node.js to create design and build single-page, multiple-page, and hybrid web applications. It has become popular among developers because of its powerful application programming interface (API) that makes routing easy. Express.js also allows you to organize web applications on the server-side into model-view-controller (MVC) architecture without being slow or heavy. As Express.js requires the use of JavaScript, it takes less effort to build web applications and API.


    MongoDB is a document-oriented NoSQL database program that makes it easy to manage databases in a flexible and scalable manner. It provides a capacity for high-volume data storage and drivers in multiple languages. MongoDB is popular among web developers because its ad hoc queries, indexing, and real-time aggregation offer an easy way to access and analyze data.

We hope this guide will help you start a career as a MERN stack developer. If you are new to the field and want to join a MERN stack development course in Nepal, you can connect with TechAxis as we provide the best MERN stack development training in Nepal.
