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
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.
Future-Proof
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.
Conclusion
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.
