What is the MERN stack?
The MERN stack is a popular web development stack that consists of four key technologies: MongoDB, Express.js, React, and Node.js. Each of these technologies plays a specific role in developing web applications.
- MongoDB — document database
- Express(.js) — Node.js web framework
- React(.js) — a client-side JavaScript framework
- Node(.js) — the premier JavaScript web server
MongoDB:
A NoSQL database that stores data in JSON-like documents. It’s a popular choice for web development because it can handle large amounts of unstructured data and scale easily.
Express.js:
A web application framework for Node.js that provides a set of features for building web applications, such as middleware, routing, and template engines.
React:
A JavaScript library for building user interfaces that allows developers to create reusable UI components. It’s popular for building single-page applications and dynamic user interfaces.
Node.js:
A JavaScript runtime environment that allows developers to run JavaScript code on the server-side. It’s popular for building scalable and high-performance web applications.
Together, these technologies provide a full-stack solution for building web applications, from the front-end user interface to the back-end server-side logic and database management. The MERN stack is known for its flexibility, scalability, and ease of use, making it a popular choice for both small and large web applications.
