Get To Know Express Framework! Why We Use It ?

Express is a web application framework for Node.js, released as free and open-source software under the MIT License. It is designed for building web applications and APIs. It has been called the de facto standard server framework for Node.js.

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. With a myriad of HTTP utility methods and middleware at your disposal, creating a robust API is quick and easy.

Express provides a thin layer of fundamental web application features, without obscuring Node.js features that you know and love. It is a supported, HTTP utility framework that can be used to build all types of web applications and APIs. It provides a robust set of features for building single, multi-page, and hybrid web applications.

One of the key features of Express is its router, which is used to define application routes and actions that are triggered when a specific URL is accessed. Routes can be used to define different actions for different HTTP verbs, such as GET, POST, PUT, DELETE, etc. This allows you to easily create APIs that support different HTTP methods.

Express also includes a number of middleware functions, which are functions that are executed before the application’s routes are handled. These middleware functions can be used to perform tasks such as parsing request bodies, adding CORS headers, or implementing authentication.

In addition to its routing and middleware features, Express also provides a number of other useful features, such as support for templating engines, and the ability to serve static files. This makes it easy to build applications that can serve HTML pages, as well as APIs that return JSON data.

Overall, Express is a powerful and flexible framework for building web applications and APIs with Node.js. Its simple, minimal design makes it easy to learn and use, while still providing all of the features you need to build modern web applications
