What is Express.JS?

Express.JS is the best backend development JavaScript library. The primary usage of it is that it helps you in developing web applications and not only that it is a type of JavaScript library that assures you that you would be able to build your application in a more efficient and fast way. Moreover, as we discussed above that JavaScript is the best language for backend development. While when you are working with express.js at that time. You also have to work on another JavaScript library, which is Node.js, for backend server-side programming.

Features of Express.js

As we have discussed what Express.JS is, let us now have a look at the features that are being offered by it to their users, which make their web application and backend development experience even better.

The first and most crucial feature that Express.JS can offer its users is that the overall programming is much easier and faster than on any other platform. If you have used pure Node.JS and Express.JS, then you must have noticed that the difference in that development of Express.JS is way faster and easier.

You must have heard about routing before, but I am sure that you must not have ever seen routing experience with Express.JS with any other platform even with Node.JS. As you may know that with routing a web application can fetch a URL that can be easily shared with other users and visitors. In the case of Express.JS, you will notice that whenever a user opens that URL, it will begin with an exact page state, while on the other with other platforms, you would not be able to get such highly advanced routing experience.

As a developer, which is the hardest thing that you have done or do? I guess everyone will talk about debugging. Although it is not a difficult task but while debugging. You had have to find the point which is showing errors and need to be corrected, and finding this point is the only challenging task. But it’s challenging for other platform users, not for Express.JS users. This is because, in the case of Express.JS, the debugging mechanism will help you in finding the point of error, and hence, you would be able to debug it easily and can save your time.

Express.JS offers the support of a template engine with the help of which you would be able to use static templates in your applications. So when you try to run the application at that time, the actual template gets changed into HTML file, and hence, it makes it easy for the client to design that page in the form of HTML.

This template engine is beneficial for developers as if the template is directly sent at the client at that time they would have first to find a way to make changes in it, but with Express.JS you would not need to do anything as it will directly provide you templates in the form of HTML so you can make changes in it easily.

Express.JS also offers support of Middleware. It is a type of system with the help of which you would be able to make changes in various features of the web application. Moreover, it will become easier for you to delete, change, or to do any such thing to those features in your application.
