MongoDB: A NoSQL, document-oriented database.
Express.js: A server-side framework for building web applications.
Working of MEAN stack:
Angular.js front end:
Express.js and Node.js Server Tier:
Express.js is the next step of MEAN stack, running on a Node.js server. Express.js is a fast, minimalist web framework for Node.js. Express.js has powerful models for URL routing and handling HTTP requests and responses.
MongoDB Database Tier:
If we need to store any data, then we need a database like MongoDB. JSON documents created in Angular.js front end are sent to the Express.js server, where they are processed and stored directly in MongoDB for later retrieval.
Advantages of MEAN stack:
Community support: Angular, one of the components of the MEAN stack, has a large community of developers who contribute to its development and improvement.
Scalability: The MEAN stack is capable of handling large and complex applications, making it a great choice for building scalable web applications.
Testing: Angular provides built-in testing tools that make it easier to test the application during development.
