MERN stack is a type of web development framework which is based on the MVC pattern. Facebook created it, and it’s used to build complex web applications.
The MERN stack consists of MongoDB as the data store, Express as a web server, React Router as a frontend router, and Nodemon as a service manager.
The MERN stack consists of three main components:
- Model– this is a data model that describes an object’s attributes and uses them for creating other objects (such as views or controllers)
- View– this component displays data from models to users.
- Controller– this component handles requests from users and processes them accordingly.
In short, the MERN stack is a way to organize your code into separate layers with clearly defined responsibilities. Each layer has its specific purpose, and they communicate using communication patterns called “verbs.”
The MERN stack is often used by start-ups and companies who want to build their applications using the latest and best practices in web development.
