Components of MERN:
Here are the details of what each of these components is used for in developing a web application when using MERN stack:
Express is a back-end web application framework for the Node.js framework. Rather than writing the code using Node.js and creating loads of Node modules, Express makes it simpler and easier to write the back-end code. Express helps in designing great web applications and APIs. Express supports many middleware’s which makes the code shorter and easier to write. As an alternative to writing full webserver code by hand on Node.js directly, developers use Express to simplify the task of writing server code. There’s no need to repeat the same code over and over. The Express framework is considered for building robust web applications and APIs. It’s known for its fast speed and modest structure, with many features available as plugins.
Advantages of a MERN Stack
1. Come with a pre-built extensive suite of technologies tools.
2. The basic building block of React is a component that maintains its state as well as renders itself. A factor summarizes the state of data and view and this is how it is rendered. By splitting an application into components allows the developers to focus on the development and reasoning of the application.
3. Feasibility of four technologies: Mongodb, express, react, node.js.
4. Supports model view controller architecture to make the development process flow smoothly.
5. As React can run on the server, its code can be used on both browsers and servers.
6. All the technologies in MERN Stack are free and open source.
7. Again, MERN stack also covers the complete development cycle – starting from frontend development to backend development.
9. MERN stack supports the MVC architecture which makes the development process hurdle free.
10. The MERN Stack comes with a set of pre-built exclusive testing tools.
11. React is a library. React library provides you with the tools to develop your application and you will get com complete freedom to choose from the library’s functions.
