What Is Vue Js

Posted on  by admin

Vue.js is a javascript framework that developers mainly use to create interactive user interfaces.

Pros and Cons of Vue.js

When compared to AngularJS, this framework is lighter and more adaptable, which is why many developers, from beginners to experts, prefer it. Javascript has no shortage of valuable frameworks to enhance the programming language’s capabilities. Vue.js is one of the most popular and widely used javascript frameworks, alongside AngularJS, another widely used framework for developing strong front end projects.

So, what is Vue.js all about? Vue.js comprises several libraries, the most important of which is the core library, which focuses on the view section of the project, which is the frontend.

Vue.js also has the following advantages:. It is simple and straightforward. It’s convenient to integrate with other libraries and projects.


Vue.js is primarily for creating interactive and visually appealing web interfaces and one-page applications. The perks of Vue.js broaden with the aid of HTML extensions and other useful plugins. Developers also use it for desktop and mobile applications.

So, how can we develop such intrinsic web interfaces? Vue comes with a feature called MVC or Model View Controller architecture. Using this architecture, developers can view the interface of their project, may it be a mobile app or a desktop app or a website.

This lightweight and functional feature explain why many developers prefer Vue.

Vue.js is also simple and quick to learn. Vue.js is an excellent place to start for beginners who are unfamiliar with the concept of frameworks. You’ll only need a fundamental understanding of HTML, CSS, and JavaScript.

As a natural consequence, you’ll be able to quickly grasp and apply the features to the project you’re working on. Learning Vue.js and adding the framework in the skills section of your resume will definitely earn you brownie points because Vue.js is one of the top 5 most used web frameworks used by developers.

Ecosystem for Development

Large corporations are using Vue.js like Nintendo, Louis Vuitton, Adobe, BMW, Google, and even Apple to design their front end-user interfaces.

Now let’s look into other compelling reasons why you should use Vue.js for UI web development:.

The size of Vue.js is one of the first and most pivotal reasons why it is more reliable and preferable. The size ranges between 18 and 21 KB, making it much easier to download and use. Vue.js, unlike its predecessors React.js and Angular.js, is lightweight and swift. Vue.js is simple to integrate into existing applications. That’s right, developers can use Vue.js to create new projects and modify existing ones because the framework provides components for practically anything.

If you are working on a project that is in dire need of a performance boost, rewriting it using Vue may be quite the help. Since modifying existing applications with Vue is so straightforward and easy, you won’t have to worry about rewriting the source code.

Instead, you can emphasise the parts that need to be altered or updated.

As an object-oriented framework, developers can write less complicated syntax codes.

Eventually, the user can easily modify parts of the code with the use of tools. Furthermore, Vue.js can render elements automatically without the need for coding, making development considerably easier and saving time and effort. Writing boilerplate code is always exhausting and time-consuming. But that’s not the case for Vue.js since the framework provides you with a lot of built-in solutions and saves you some time.

The goal of Vue.js is to assist developers by saving them time and reducing complications. Vue-CLI is one such function that is quite useful to developers. This application allows you to configure, execute, analyse, and test a project using the tools of your choice.

Vue-CLI is far more flexible, with a large number of pre-configured settings.

Vue is a user-friendly platform that offers assistance and essential tools to developers, making programming considerably easier.

Now we know how helpful Vue.js can be. Before beginning to learn Vue.js, here are some features you should know:.

Virtual DOM is utilised by Vue.js, as well as other frameworks like React, Ember, and others. Instead of implementing changes to the DOM, a replica of the DOM is constructed and stored in the form of JavaScript data structures.

Any modifications to the JavaScript data structures are made first, and then the latter is compared to the original data structure. The final changes are subsequently applied to the real DOM, where they will be visible to the user.

This is advantageous in terms of optimisation because it is less expensive and allows for faster modifications.


With the help of a binding directive called v-bind provided by Vue.js, the data binding functionality allows you to edit or assign values to HTML attributes, change the style, and assign classes.

Vue.js offers a built-in transition component that must be wrapped around the element for the transition effect. When HTML elements are added, changed, or removed from the DOM, Vue.js provides a variety of ways to apply the transition.

We can easily integrate third-party animation libraries and increase the interface’s interactivity. Vue.js has built-in directives to perform various actions on the front end.

They are: v-if, v-else, v-show, v-on, v-bind, and v-model.

What Is Vue.js Used For?

Conditional data binding is provided by a primary yet effective function. This function is similar to the if and if-else statements we use in other languages such as python, C++ etc. Users can instruct Vue only to connect data if a specific value is true.

The directives v-if and v-else can be used for this. The v-if template executes if the value a programmer wants to assess is true.

Otherwise, the v-else option is invoked. Vue.js also includes a basic API protocol for looping through arrays.

It’s as simple as getting the target array and inserting the v-for directive. Furthermore, because the array relates to objects, users will be able to see properties right here. Separate entities that distinct properties can iterate can also use the v-for feature.

Users in Vue can also use components that are similar in many aspects in other libraries.

To construct these objects, you’ll need to use Vue.component, which has a name or identifier as well as a configuration. Coders can provide templates and anticipated properties to be inserted into the DOM. Developers can pass the props using the v-bind function. Events contain the complete history of the interaction between users and apps.

Because circumstances can be challenging to handle, developers can assign handlers to tell apps what to do when a specific event is triggered. In Vue, programmers create events with v-on directives along with colons to specify the event’s type.

What Is Vue.js?

For instance, v-on: click. Vue.js has this as one of its distinguishing features. It assists in understanding the changes made to the UI elements and executes the required actions without the need for further coding. The code is fast and straightforward because Watcher handles any data updates.

  1. When data changes, watchers are applied. Form input elements, for example. We don’t need to add any further events in this case. Developers use Vue-router to navigate from one page to the next. Vue.js, like every other programming language or framework, has its own set of advantages and disadvantages.

  2. Let’s have a look at the pros and cons of Vue.js:. Lightweight – The Vue.js framework is a lightweight framework. It simply takes about 18 kb and a few seconds to download.

Easy to Learn – Unlike other frameworks like Angular and React, which is known to have massive and complicated libraries and require particular notions such as JSX or TypeScript to fathom them. To completely comprehend and grasp the framework, you only need a rudimentary understanding of HTML, CSS, and javascript.

Features of Vue.js

A Powerful Set of Tools – Vue.js includes a robust collection of tools for unit and end-to-end testing, as well as a plugin installation system. Add in the fact that Vue.js has its own browser.

Debugging tools, server renderer, and state manager are other useful tools provided by Vue.js.

Active Community – Vue.js has a vibrant online community that is not only active but also supportive.
Github, Stackoverflow, Reddit, and discord all have sections dedicated to resolving any issue that novices to Vue.js are likely to encounter.
