<h2>Express JS Features</h2>

 
<b>1. Quicker Server-Side Development</b>

Express JS offers many Node JS features, which are used quite commonly in the form of functions that one can use readily anywhere within the program. In this way, it is not required to code for an extended period, thus saving time in the long run.

 
<b>2. Middleware</b>

 This is a component of the program having access to client requests, databases, and other middlewares. Middleware is primarily accountable for the systematic arrangement of various Express JS functions.

 
<b>3. Routing</b>

A somewhat advanced routing mechanism is offered by Express.js development that aids in preserving the web page’s condition using their URLs.

 
<b>4. Templating</b>

Templating engines are provided by Express JS that enable the developers to create dynamic content on web pages by developing HTML templates.

 
<b>5. Debugging</b>

Debugging is essential in case you like to develop web applications successfully. Debugging is made more accessible by Express JS by offering a mechanism that can pinpoint the web app’s specific component having bugs.

<b>Express JS Benefits for Back-End Development</b>

 Here, we will be talking about some of the top advantages of making use of Express.JS for back-end development.

 
<b>1. Scale the Application Quickly</b>

The most notable advantage of using Express.JS for back-end development is that it would be feasible to quickly scale the application. As you might be aware, there is additional support provided by Node.JS. So, with the aid of the addition in nodes plus adding additional resources to it, it will be possible to scale your application quickly.

 
<b>2. JavaScript is Not Difficult to Learn</b>

JavaScript happens to be extremely famous and simple to learn the language. It can be easily used for development on Express.JS.

 
<b>3. The Same Language can be used for Coding Front-end</b>

One more advantage of employing Express.JS is that it will be feasible to perform the code of frontend and back-end using JavaScript. Even though you will come across several such platforms, different language support is offered by them for front-end and back-end, which makes it quite perplexing to work with. Nevertheless, no such problem will be faced by you while with Express.JS.


 
<b>4. Fewer Developer Expenses for Maintaining the App</b>

It is not known to everybody that Express.JS happens to be a full-stack JavaScript, due to which there is no need to hire different back-end development services for managing the front-end and the back-end of a web app.

 
<b>5. Google V8 Engine Supports It</b>

The Google V8 engine supports Express.JS; using it will be possible to get better performance without any error or lag in the processing.

 
<b>6. Quick Development</b>

One reason why web frameworks are used at present is that people like to create their apps quicker. The process of development becomes easier and smoother by making use of frameworks. When you use a contemporary framework such as Express, you need to write code for every feature from scratch that you like to develop.

Express provides pre-made libraries, functions, and tools that help accelerate the process of web development. The frameworks created using this tool, including Poet, Feathers, LoopBack, and Kites, will help you accomplish lots of boring development tasks quite quickly.

Express likewise allows you to write your middleware functions to reduce the lines of code you need for writing, thus saving you effort and time. The framework similarly offers a collection of pre-built middleware functions for the quick development of apps. For building things even quicker, 3rd-party middleware functions can be used by you to easily extend the Express app functionalities.

You will come across various types of middleware, including third-party middleware, error-handling middleware, router-level middleware, inbuilt middleware, in addition to application-level middleware.

There are several process managers and template engines that you can use to make the development process much smoother.

Some well-known template engines happen to be Pug, h4e, Eta, Marko, swig, EJS, and Blade. Moreover, some of the popular process managers for Express JS are SystemD, PM2, StrongLoop Process Manager, and Forever.

 
<b>7. Community Support</b>

In case while working with Express.JS, you are facing any issue, it will be a good idea to take help from the community, which happens to be highly supportive.

 
<b>8. Supports Caching</b>

Express.js support the caching feature, and its benefit is that there is no need to re-execute the codes repeatedly. Furthermore, it will allow the web pages to load quicker.
