Why To Use Vue JS for Web App Development

The modern web is constantly evolving. New tools are emerging every year, and it is not always clear what tool would be best to use in a particular situation. One of the most popular front-end development tools at the moment is Vue JS. It’s an open-source JavaScript framework for building user interfaces for single-page applications.

Vue JS was created by Evan You, who previously worked on AngularJS at Google. He extracted the part that he liked from Angular and built a lightweight framework around it. There are several benefits offered by the Vue framework that combines some of React and Angular – but it’s also much lighter than both of them as it weighs only 20kb.

The main goal of Vue JS is to provide the benefits of reactive data binding and composable view components with an API that is as simple as possible. It has focused on the view layer and it is very easy to use. 

Vue JS has become one of the best progressive JavaScript frameworks lately. It has a simple integration, an easy learning curve, and high performance. Let’s see why you should consider Vue for the development of your next web application.

Why Vue JS?

Ease of Learning

The core library of VueJS is focused on the view layer, making it easy to integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single Page Applications when used in combination with modern tooling and supporting libraries.

Vue offers official support for TypeScript out of the box. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. Using TypeScript ensures that all validations are done by the compiler and hence less error-prone and results in higher quality code. It helps you catch errors and provide fixes before you run your code.

Higher Performance

It is specially designed to provide higher performance. Vue.js offers a comprehensive solution to cover various design patterns and components needed in developing an interface. The performance is optimized by not updating the DOM directly, but using a virtual DOM instead, and the framework only re-renders the parts of the UI that changed actually.

Progressive Framework

Vue can be adopted incrementally. It means that we can develop a web app using Vue by taking one step at a time. It is very convenient for developers to migrate from existing JS frameworks to Vue because it does not require any rewriting of the existing code.

Simple Integration

Vue can be easily integrated into big projects as well as small ones without causing any problems with existing code due to its size and design choices that allow you to gradually add more features without breaking anything in the process.


Flexibility is one of the essential features of Vue JS development. It allows you to use the same component in different projects by increasing the reusability of code. This feature reduces the time required to develop functionalities and speeds up the development process by eliminating repetitive tasks. Vue JS can be used to build large-scale applications and also simple web pages.

Detailed Documentation

Vue JS has detailed documentation with a lot of examples so you can easily learn how to work with this framework and utilize its various components. The documentation for Vue.js includes a number of introductory guides as well as detailed API reference documentation. 

The guide assumes very little prior knowledge about JavaScript, but rather focuses on the basics of Vue development and explains some of the underlying concepts along the way.

Reactive Data Binding (Two-Way Binding):

Vue JS provides two-way data binding that helps you to manipulate or assign values to HTML attributes, change the style, and assign classes. In return, when the value of a component changes, it will affect the corresponding DOM element. This feature makes it more straightforward for developers to handle HTML blocks directly without any complicated code.

Conditional data binding

Conditional data binding is also one of the key strengths of Vue.js. It allows you to show/hide elements and change their styles based on a condition.

v-show directive - The v-show directive shows/hides HTML elements based on the value of an expression. For example, if you want to hide an element using v-show directive, the element will still be present in the DOM, but it will not be visible to the user.

v-if directive - The v-if directive is a bit different from v-show. It removes the element from DOM when the expression evaluates to false. This helps in improving application performance as your app doesn't have to render unnecessary content.

Computed Properties

Computed Properties are by far the most important concept in Vue.js. They can be considered functions that help you to manipulate and return a value based on its dependencies.

A computed property will act as a watcher for any changes in the properties it uses to derive its own value. As soon as there is a change, the computed property will update. It will not re-evaluate if there is no change in the data it depends on.

Computed properties are very useful when we want to perform some kind of operation on our data before displaying it to the user, or when we need to display some related information that is not directly available on an object. For instance, we have an array of product objects, each with a price and quantity property. We need to show the total price of all products - price * quantity - but this is not available directly on any product object.


Vue.js makes it easier to develop large-scale applications. It has a Virtual DOM which enables faster rendering and support for server-side rendering. Vue can be used as a base in the development of single-page applications when it comes to structuring and routing web pages.

Apart from that, it can also be used as a simple web page or feature on an existing page. This allows you to integrate new features into your existing project instead of rewriting the project from scratch.


As you see, Vue.js has a lot of pros, but probably the main one is that it is extremely lightweight. This can be very important when creating a complex application or a website. A lot of companies are starting to use Vue.js, and there are big names behind this technology. 

It has extremely good documentation and there is always room for improvement – which is a great place to start from as this means that the software will forever be evolving and improving. This also means that there are tutorials, learning resources, and community support for people who want to learn this framework.
