Mean Stack refers is a collection of JavaScript technologies that are useful in developing web applications. Basically, starting from the client to the server and further from the server to the database, everything is built on JavaScript. Therefore, MEAN is a full-stack development toolkit that enables the development of fast and robust web applications. Whereas, a MEAN Stack Developer is a JavaScript-supporting application programmer who works with MEAN stack (MongoDB, ExpressJS, AngularJS, NodeJS). However, to learn more about it, you can target Mean Stack Developer Training in Gurgaon for a better understanding. Also, these developers work on both the backend as well as front-end of the application. Hence, a Mean stack developer must have in-depth knowledge of JavaScript as all of its applications are based on JavaScript.
MEAN works on four different technologies;
- MongoDB: It stores and retrieves data.
- Express JS: This framework supports the development of web applications in Node.
- AngularJS: It is a JavaScript framework made by Google
- js: It is a server-side JavaScript execution environment
A brief about Mean Stack Architecture
MongoDB: It is an open-source, cross-platform database that is written in C++. This database stores data in the key-value pair, with the help of binary data types like JSON. Basically, it is a document-oriented NoSQL Database that resembles an Object in OOPS. Mongo DB is a convenient option for a database system where you require to manage large-sized tables with millions of data. Also, it is easy to include a field in Mongo DB and does not require updating the entire table. Further, with Mongo DB you can build an entire application with just one application which is JavaScript.
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.
Angular JS: Angular JS works as an open-source JavaScript framework. Angular is maintained by Google. The aim of this framework is to initiate MVC (Model View Controller) architecture in the browser-based application to make the development and testing process easier. Further, this framework enables you to create a smarter web app that supports personalization. Also, AngularJS allows the use of HTML as a template language. Hence, you can extend HTML’s syntax to express the components of your application. Angular features like dependency injection and data binding remove many codes that you require to write.
Node JS: With Node.js developers create web servers and build web applications on them. This is basically a server-side Javascript execution environment. Further, Node.js works on a non-blocking and event-driven I/O model. This also makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Moreover, it enables developers to create data-intensive real-time apps that can run across distributed devices. Also, you can run Node.js runtime on Microsoft Windows, OS X, and Linux.
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.
CONCLUSION
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. To get a better idea about this application, Mean Stack Developer Course Online will guide you better through the journey. Therefore, owing to its easy availability and easy-to-use feature, it is widely accepted across companies.
