Mean Stack Tutorial

Web Development plays a vital role in this competitive world in order to make it more prominent, one of the technologies called MEAN stack is an excellent choice to build applications based on the web. By using MEAN stack, it is very easy to deploy and develop a wide variety of application to the cloud. The collective group of JavaScript-based technologies, which are mainly used for developing different kinds of web applications is referred to as MEAN stack. 

What is a MEAN Stack ?

MEAN is a relative collection of document databases and javascript frameworks such as MongoDB, ExpressJS, AngularJS, and Node.js.  MEAN is an end to end JavaScript stack mainly designed to create cloud-hosted applications. This MEAN has its own web server present in it, which will be surging to optimize the world of cloud by exploiting performance and cost savings. 

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.

Features of MEAN Stack

  1. It is designed in order to manage large amounts of data with high scalability and flexibility.
  2. MEAN builds extensible applications which are amended for cloud deployment.
  3. Streamline deployment is performed with a built-in server.
  4. Development of entire application using a single language.

Applications where MEAN is Used

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,

  1. Tracking location and Mapping
  2. Calendars
  3. News aggregation sites and 
  4. Expense tracking

Components Role in Stack

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.

MongoDB - It is an open source, NoSQL, and cross-platform database, which is designed to manage large volumes of data present in tables. The advantage of using MongoDB is to develop an entire application with one core source called JavaScript.

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.
