Getting to know MERN Stack components:
- MongoDB: Cross-platform Document-Oriented Database
2. Express: Back-End Framework:
Express is a 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 middlewares which makes the code shorter and easier to write.
3. React: Front-End Library
4. Node.js: JS Runtime Environment
Why choose the MERN stack?
MongoDB works extremely well with Node.js, and makes storing, manipulating, and representing JSON data at every tier of your application incredibly easy. For cloud-native applications, MongoDB Atlas makes it even easier, by giving you an auto-scaling MongoDB cluster on the cloud provider of your choice, as easy as a few button clicks.
The combination means that JSON data flows naturally from front to back, making it fast to build on and reasonably simple to debug. Plus, you only have to know one programming language, and the JSON document structure, to understand the whole system!
MERN is the stack of choice for today’s web developers looking to move quickly, particularly for those with React.js experience.
