MEAN Stack

MEAN was first introduced by a developer named Valeri Karpov. He made his first MEAN application in 2013, and released it under the MIT license, which means anyone can download it and use it for free.

The MEAN stack is a group of technologies that can be used together to build web applications. The term stack refers to the layers involved in building an application—the "MEAN" part stands for MongoDB, Express.js, Angular.js, and Node.js, the four technologies that make up each layer in the stack.

Since then, MEAN has been adopted by many developers as a more efficient way to create web applications. The main reason is because MEAN uses JavaScript on both the front-end and back-end of applications—this saves time because developers only need to learn one language instead of two (e.g., HTML/CSS/JavaScript vs PHP or Python). Also, you can develop and test your application locally on your computer without having to set up a server for hosting (as is required for other stacks like LAMP).

The MEAN stack is a popular technology stack for building web applications. The name stands for MongoDB, Express, Angular, and Node.js. It includes everything you need to build a complete web application.

Each layer of the MEAN stack is built on top of the next, making it easy to set up and maintain an entire web application using only JavaScript technologies.

MEAN stands for MongoDB, Express, Angular and Node. The MEAN stack is a popular web development stack made up of MongoDB, Express, Angular (formerly Angular.js), and Node.js. It provides an end-to-end framework for developers to work in. This term was first coined by Valeri Karpov while he was coding a demo application.

MongoDB is the leading NoSQL database, empowering businesses to be more agile and scalable. Express is a minimal and flexible node.js web application framework that provides a robust set of features for web and mobile applications. AngularJS lets you extend HTML vocabulary for your application. The resulting environment is extraordinarily expressive, readable, and quick to develop. Node is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

MongoDB

MongoDB is a document database that stores data in JSON-like documents. MongoDB is the database layer of the MEAN stack.

Express

Express is the web server framework for Node.js, which runs on the server. Express is the server layer of the MEAN stack.

Angular

Angular is a client-side JavaScript framework that runs in a user's browser, and it's what drives most of the functionality in modern websites. Angular is the client layer of the MEAN stack.

Node

Node handles all of the functionality to do with web servers, such as receiving requests from users, handling those requests, and sending responses back to those users. Node is the server layer of the MEAN stack.

MongoDB is the database that stores your application’s data. Express is a Node.js server framework that provides routing capabilities and other features needed to build web applications. Angular is a client-side JavaScript framework that provides MVC functionality in the browser; it makes building user interfaces easier than using vanilla JavaScript or JQuery. Node.js is a JavaScript runtime environment that lets you run JavaScript in the server; it’s what makes running your Express server possible.
