MongoDB, Express, React / Redux, and Node.js make up the MERN stack. The MERN stack is one of the most popular stacks of technologies for constructing a modern single-page app, thanks to the popularity of React on the frontend and Node.js on the backend.
Here’s how a typical stack is put together:
- As a NoSQL database, MongoDB
- An open-source document database that allows application data to persist.
- Bridges the gap between quick and scalable key-value stores and relational databases (rich functionality).
- Data is stored in collections with dynamic schemas as JSON documents.
- Scalability and developer agility are priorities.
- It pairs well with Node.js apps because it is designed to be used asynchronous
The Node.js Express web framework includes routing and middleware
- The backend code is run as a module within the Node.js environment.
- Handles request routing to the appropriate areas of your programme.
React.js is a dynamic frontend framework
- Facebook’s JavaScript library for creating interactive and reactive interfaces.
On the server, Node.js is used
- A runtime environment for javascript.
- An asynchronous event-driven engine implies the programme sends a request for data and then waits for a response while doing other things.
In the JavaScript web app race, the MERN stack wasn’t always the frontrunner. Many companies and developers still use the MEAN stack development, which is similar to the MERN stack but uses AngularJS or Angular for the frontend instead of React. The virtual DOM modification is one of React’s distinctive features, which helps keep apps dynamic and speedy.
