MERN Stack comprises of four technologies namely:
MongoDB, Express, React and Node.js.
It is designed to make the development process smoother and easier. Each of these 4 powerful technologies are introduced by a complete online MERN training that provides an end-to-end framework for the developers to work in and each of these technologies play a big part in the development of web applications.
Why use MongoDB?
• Schema Less
• Data keep within the type of JSON
• Simple atmosphere Setup
• Flexible Document Model
2. Express: Back-End Framework: Express may be a Node.js framework. Instead of writing the code mistreatment Node.js and making countless Node modules, makes (Express) it easier and easier to note the back-end code. Planning & designing the web applications and genus API. Another module learn in MERN online training course which supports several middleware’s that makes the code shorter and easier to jot down.
Why use EXPRESS?
• Asynchronous and Single-threaded.
• Efficient, quick & scalable
• Largest community for Node.js
• Express promotes code reusability with its inbuilt router.
• Robust API
3. React: Front-End Framework
used for building user interfaces which
can be studies by MERN online training.
React is employed for the event of single-page
applications and mobile applications
owing to its ability to handle apace dynamic
knowledge. React permits users to code in
Why use React?
• Virtual DOM –
A virtual DOM object may be illustration of a DOM object. Virtual DOM is truly a replica of the first DOM. Any modification within the net application causes the complete UI to re-render the virtual DOM. Then the distinction between the first DOM and this virtual DOM is compared and also the changes area unit created consequently to the first DOM.
• Parts – React JS supports Components. Parts area unit the building blocks of UI whereby every part includes logic and contributes to the UI. These parts additionally promote code reusability and create the net application easier to know.
• High Performance – options like Virtual DOM, JSX and parts makes it abundant quicker than the remainder of the frameworks out there.
4. Node.js: JS Runtime surroundings
Why use Node.JS?
• Single threading
• Data Streaming
• Highly Scalable
Initialize a Node.JS application by writing running the below command within the command window. Therefore, it is one of the technologies growing in the market with a rapid speed in the field of Web Programming.
