MEAN works on four different technologies;
- MongoDB: It stores and retrieves data.
- Express JS: This framework supports the development of web applications in Node.
A brief about Mean Stack Architecture
Express.JS: Express is a flexible, mature, lightweight server framework. It is useful in designing and building single, multi-page, and hybrid web applications. However, this framework uses the Pug engine to enable support for templates. Basically, Express is the de-facto framework for Nodejs and draws heavy inspiration from Sinatra, the popular Ruby framework.
The flow of requests under the Mean Stack Application
Step 1: Initially, the client places a request given by AngularJS
Step 2: Now, the request moves to NodeJS which will break up the request.
Step 3: Further, ExpressJs will make calls to MongoDB to get or set data.
Step 4: Then, MongoDB retrieves the requested data and return that request to the Express JS
Step 5: After this, NodeJS return the request to the client.
Step 6: Finally, on the client side, AngularJS displays the result fetched from MongoDB.
Basically, MEAN is a user-friendly stack that is the ideal solution for building dynamic websites and applications. It is also a free and open-source stack that offers a quick and structured method for developing rapid prototypes for web-based applications. Further, more and more companies consider MEAN Stack Developers as their preferred choice of employees. Because they can make a full-stack application.
