Building Quick Low-Cost Apps – How Express.JS Makes it Possible

Creating quick low cost apps with the help of Express.JS

Over the last few years, JavaScript has transformed into a highly developed programming language. Many developers are getting interested in using JavaScript, and it’s becoming the most popular language in the world. At present, a large number of libraries and frameworks are built using JavaScript. It is a very easy language to learn, works well when combined with other languages ​​and can be used in a variety of applications. Similarly, Node.JS has become a trending language when it comes to backend programming. With many big brands and heavy traffic attracting websites like eBay, Yahoo, Microsoft, Netflix, LinkedIn, and more, using Node.JS for their platform, it has surpassed its contemporaries to become the most valued programming language. 

Express.JS, which is a minimal and flexible Node.JS web application framework that provides a robust set of features for web and mobile applications, is its right hand that has helped escalate it to newer heights. 

Node.JS is known as an event-driven I/O server-side JavaScript environment and single-threaded event loop based on Google’s open source high-performance JavaScript engine – V8. It is appreciated for its event-driven architecture as it plays an important role in developing real-time applications, especially chat and streaming applications. As both the client-side and the server-side codes are written in JavaScript when developing such applications, the synchronization process is better and quicker.

Express.JS – Role in App Development?

Express.js is a free and open-source web application framework for Node.js that plays an important role in helping build web applications quickly and more easily. Creating an Express app, as the name suggests, is quick and only requires the hired Express.JS developer to have a thorough understanding of JavaScript.

Since Express.JS is a framework of Node.JS, most of the code is already written for the programmers to work with. A business can simply hire an Express.JS developer to develop its single-page, multi-page, or hybrid web application. Being a lightweight framework, Express.JS can organize web applications on the server-side into a more organized MVC architecture.

Express.JS is a part of the JavaScript-based technology called MEAN software stack, which is short for MongoDB, Express.JS, Angular.JS, and Node.JS. 

Express.js is the backend part of MEAN and manages routing, sessions, HTTP requests, error handling, etc. The framework is armed with a vast JavaScript library that helps programmers build efficient and fast web apps.  In short, Express.js enhances the functionality of the node.JS by making the programming part effortless and adding a number of great features.

A number of features make creating an Express app using a low budget and in lesser time. The most important features of Express.JS that contribute to this include:

features of Express.JS

1. Faster Server Side Development

Express.js provides many commonly used features of Node.JS in the form of functions that can be readily used anywhere in the program. This removes the need to code for several hours, thus saving time.

2. Middleware

Middleware is a part of the program that has access to the database, client requests, and the other important functions. It is mainly responsible for the systematic organization of different functions of Express.JS.These functions are easier to recall with the help of Express.JS and thus contribute to saving time when using Express.JS to build apps.

3. Routing

Express.JS provides a highly advanced routing mechanism which allows the programmer to preserve the state of the webpage with the help of their URLs. This in turn saves time, money, and effort when developing an app. 

4. Templating

Express.JS provides templating engines that allow the developers to build dynamic content on the web pages by building HTML templates on the server-side. Thus, Express.JS makes it possible to build a multi-page web app with ease.

5. Debugging

Debugging is extremely crucial when it comes to the successful development of web applications. Express.JS makes debugging easier by providing a debugging mechanism that has the ability to pinpoint the exact part of the web application which has bugs. Thus, the hired Express.JS app developer can save time and effort during the testing phase of the app as well.

Apart from the above-listed points, Express.JS has many other advantages that contribute to a smooth and stress-free app building process. The advantages are listed below:

Advantages ExpressJS Infographics
  • Easy to Learn

Express.JS is easy to learn as many front end users are already familiar with JavaScript. This is why they do not need to learn a new language in order to learn Express.JS.

  • Easier Backend Development

Express.JS makes backend development much easier for front end developers as well and the business does not need to hire separate set of programmers for the same app.

  • Single Language Used – JavaScript

A web developer can use JavaScript as a single language for both front end and back end development. The developer does not need to learn or use any other language for server-side development.

  • Quick and Easy Implementation of Code

The JavaScript Code is interpreted through Google V8 JavaScript Engine by Node.js. Therefore, the code is implemented quickly and easily in an effective manner.

  • Easy to Customize

The Express.js framework is very simple to customize and use as per the needs of the business app.

  • Flexible Middleware Module

Express.js provides a flexible middleware module. It is mainly useful for doing extra tasks on response and request.

JavaScript has proven to be the undisputed leader and the most universal software development technologies available to date. Node.JS and Express.JS together make JavaScript a full-stack technology of choice for app development. With the introduction of Express.JS framework, Node.JS has been bolstered to outperform other programming languages and churn out quick and easy apps for businesses.
