Express Js

Express.js is a small framework that works on top of Node.js web server functionality to simplify its APIs and add helpful new features.

Building a backend from-scratch for an application in Node.js can be tedious and time consuming. From setting up ports to route handlers, writing all of the boilerplate code takes away from what really matters, which is writing the business logic for an application. By using web frameworks like Express.js, developers can save time and focus on other important tasks.

• Scalability
• Community support
• Easy to learn
• Performance
• Rapid development
• Real-time applications
• Advantages of Using Express With Node. js

• Express is Unopinionated, and we can customize it.
• For request handling, we can use Middleware.
• A single language is used for frontend and backend development.
• Express is fast to link it with databases like MySQL, MongoDB, etc.
• Advantages of ExpressJS:

1. Minimal and Lightweight

Express.js is a minimal and lightweight web framework that provides developers with a basic set of features for building web applications. It is designed to be flexible and modular, allowing developers to easily add new functionality as needed. Express.js does not include a lot of unnecessary features, making it fast and efficient.

2. Easy to Learn and Use

Express.js is easy to learn and use, making it an ideal choice for both novice and experienced developers. It provides developers with a simple and intuitive API for building web applications. Express.js is built on top of Node.js, which means that developers can leverage the power of the Node.js ecosystem and easily integrate with other Node.js modules.

Middleware Support

One of the key features of Express.js is its support for middleware. Middleware is a function that is executed for every HTTP request that is received by the server. Middleware can be used to perform a variety of tasks, such as logging, authentication, and error handling. Express.js provides developers with a wide range of built-in middleware functions, as well as the ability to create custom middleware.

4. Routing

Express.js provides developers with a powerful routing system that makes it easy to handle different HTTP requests for different URLs. Developers can define routes that map to specific URLs and HTTP methods, making it easy to handle different types of requests. Express.js also supports parameterized routes, which allows developers to handle dynamic URLs.
