The entire architecture can be explained in 5 steps:
Step 1: Client makes a request first, which is handled by AngularJS.
Step 2: Then, the request will be passed onto the NodeJS Server called as a parse request.
Step 3: In step3 the ExpressJS will call MongoDB to set the data, the MongoDB retrieves the requested data and returns to ExpressJS.
Step 4: NodeJS will return the requested data to the client.
Step 5: In the final step AngularJS will display the result fetched from MongoDB.
MEAN may not be perfect for all the applications in an environment, there are some specific applications where it is being used. The cloud-native applications make it a strong choice due to its flexibility, scalability, and its ability to manage coeval users. The innovative applications using MEAN include,
Components in the stack are made up of four different technologies which is the acronym of MEAN. MongoDB, ExpressJS, AngularJS, and Node.js technologies play a major role in developing an ideal solution for building various fast and robust web-based applications.
Express.JS - It acts as a backend for MEAN stack to handle all the operations in between database and front-end. This is a web application framework for Node.js, which is structured to ensure a secure and smooth transfer of data to end users.
AngularJS - This technology in the stack is used to help developers build user-friendly applications to make the testing process easier.
NodeJS - The strength of this is its scalability and it also acts as the backbone for MEAN stack. It is mainly designed for fast data serving.
