Step By Step MERN Stack Developer Roadmap-

Now, that you got the basic idea about MERN stack and why you need to learn it! let’s get started with the complete and step by step mern stack developer roadmap!!

Learning Fundamentals (HTML, CSS, JS)-

So, before diving into MERN stack, you need to have a strong foundation in the basics of web development. This includes HTML, CSS and JavaScript. HTML is used for creating the structure of web pages, CSS is used for styling, and JavaScript is used for adding interactivity and functionality in the website. Now, you don’t need to master html, CSS and JavaScript instead just learn the basics of them and move forward. And trust me guys this is the best way to learn web development faster. Here is a list of basic concepts to learn in HTML which includes semantic tags, tables and unordered lists. For CSS, here is the list of key concepts to understand which includes knowing the flexbox layout and understanding the box model. And for JavaScript, you should learn the basics of the language, including variables, data types, functions, loops and control statements. Plus you should focus on ES6 features which includes array destructuring, object destructuring, rest operator, spread operator, array methods such as map, filter and reduce as they would help you a lot in react.

Learn CSS Frameworks-

Now, once you have learned the fundamentals, i highly recommend that you should learn some of the CSS frameworks. Like, you can learn tailwind and bootstrap. However, I love tailwind CSS. And i use Tailwind in most of my projects. You can also use CSS preprocessors like, SAAS that will give some extra power to your ordinary CSS and manage your CSS a lot. With SAAS you can use variables and functions to group your CSS code that will of course help you increase efficiency and productivity.

Learn React (Frontend)-

Now, similar to tailwind and bootstrap that are CSS frameworks and that are used to make CSS easier for you. JavaScript also has some frameworks that make JavaScript easier to use. And hence React is one of them which is one of the most popular JavaScript framework that is used to create modern single page web applications. Single page means that they do not have the weird loading spinner at every click. A react app only holds single html file. It allows developers to build interactive and dynamic user interfaces using reusable components. To become a pro MERN stack developer, you should learn react and some of it’s important concepts, including JSX, components, props, state, and hooks. To get started with React, you can create a simple project and use the create-react-app using vite to build and run your project. You can also learn Next.js which is a complete react framework that uses react and that is also considered as the future of web development which includes modern web development concepts such as server side rendering and static site generation. So, learn how to create components, how to use props to pass data between components, and manage state using modern react specific tools and packages such as redux. With redux you can manage your entire react application state. And can create complex front end applications very easily.

Learn Node.js & Express.js (Backend)-

Node.js is a JavaScript runtime that can help developers to run JavaScript on the server-side or in the backend. This is used to create restful APIs very easily. The best thing about node.js is that it uses JavaScript. And as you already know JavaScript hence you can learn node.js in a very short amount of time. And hence MERN stack is the fastest way to learn web development these days. You should learn how to create a server in node.js. how to create an api and how to connect your node.js to your react front-end.

Learn MongoDB (Database)-

Finally, to complete the full stack web development process you should learn a database and mern stack uses Mongodb hence it is a very popular NoSQL database that you can use to store data. So, you need to learn how to connect node.js application to database and store the data, how to perform the CRUD operation which is acronym for create, read, update and delete.
