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
On the server, Node.js is used
- An asynchronous event-driven engine implies the programme sends a request for data and then waits for a response while doing other things.
