A MEAN stack application is a type of web application that uses the MEAN stack, which is a collection of JavaScript-based technologies, including MongoDB, ExpressJS, AngularJS, and Node.js.
MongoDB is a NoSQL database, which allows for the storage and retrieval of data in a JSON-like format. It is a popular choice for web applications because it is flexible and can handle large amounts of unstructured data.
ExpressJS is a web application framework built on top of Node.js. It simplifies the process of handling HTTP requests and responses, and it provides a robust set of features for web and mobile applications.
AngularJS is a JavaScript framework for building dynamic, single-page web applications. It allows for the creation of reusable components and the use of two-way data binding, which enables a seamless connection between the user interface and the data model.
Node.js is a JavaScript runtime environment that allows for the execution of JavaScript code on the server side. It is built on Chrome’s V8 JavaScript engine, and it enables the creation of high-performance, scalable, and real-time web applications.
Together, these technologies form a MEAN stack, which allows for the development of full-stack web applications using only JavaScript. This makes it a popular choice among developers, as it allows for a uniform language throughout the entire application stack and enables faster development and more efficient maintenance.
Overall, a MEAN stack application is a web application that uses MongoDB, ExpressJS, AngularJS, and Node.js to handle the database, the server-side logic, the client-side logic, and the server runtime respectively. It allows developers to use one language throughout the entire application stack, and makes it easier to maintain and scale.
