10 Reasons Why Vue.js is Gaining Popularity In 2021


The success of Vue.js as a web app development framework is generally attributed to its flexibility and wide range of resources that are available free of cost. The progressive framework built on JavaScript can be used for building applications in any user interface.

As of September 2021, Vue.js has a whopping 188k stars rank that sets it apart from other competitors. Its flexible architecture allows extra insight into declarative rendering and component composition. The extensive core library of Vue.js focuses entirely on the view layer and has the most enriching ecosystem.

If Vue.js still sounds unfamiliar, read on to find out more about the framework!

What Is The Vue.js Framework?

For developing user interfaces, the progressive framework, Vue.js, is the ideal solution. It is an open-source, front-end framework built upon the model-view-ViewModel architectural pattern used for developing single-page applications and user interfaces. This makes the view layer independent of any specific host model platform.

The Origin Story:

The Vue.js framework was first created by Evan You, with its first source code committed in 2013, followed by its first release in February 2014. You, an engineer with Google by profession back then, encountered problems with the AngularJS they were using for multiple projects. He wanted to build something more compact and lightweight and thus was born his brainchild, the Vue.js development framework.

Quirky Version Names:

Interestingly, the different version names of the Vue.js updates are inspired by various anime and manga, mainly in the shounen genre - the latest version being titled "Quintessential Quintuplets." This trivial pop culture reference makes the framework even more endearing to its users.

Why Is Vue.js Gaining So Much Popularity?

Vuejs frameworks flaunt features that set the trend in the web development industry. It allows students, small business owners, and even large corporate companies to build applications for any interface for absolutely zero cost. Vue.js employs high decoupling by isolating variables like the front and back end and works only with the former.

According to Stack Overflow's Developer Survey 2021, held in May this year, Vue.js ranked fifth, keeping in step with tech giants like React and AngularJS. What led to this stardom of the Vue.js?

Lightweight Framework:

This is the major goal that has led to the production of Vue.js. The size of Vue.js is small and does not take up too much space. It is super light, taking up only 18 KB of memory of one's device in a downloaded zip file.

The lightweight Vue.js framework thus gets downloaded quickly onto any interface. Even the installation of the library full of resources takes only a few minutes. So, the developers who have to build apps at the beck and call of their company can use this framework for quick delivery. Additionally, the light Vue.js framework also boosts User Experience (UX) and Search Engine Optimization (SEO).

Convenient And Comprehensive:

Developers can easily use Vue.js because of its smooth, comprehensive workings. A developer no longer needs an in-depth knowledge of different programming languages to set up a front-end technology with Vue.js. With Sublime Text, one can easily test out Vue. Essential knowledge of HTML, CSS, and JavaScript is enough for web app development with this framework. Even the most popular code editing tools like Visual Studio and Atom support Vue.

By using Vue UI or Vue command-line interface, configuration and arrangement of the app can be made in a way that it can utilize all the features quickly. If a developer faces any problem, Vue's extensive community and documentation can easily help them out with necessary references.

Interactive Features:

Interactive features like transition and animation are fast to get people hooked onto the app. Statistically, it can increase the duration of how long the audience stays on the page. In fact, every app and website has interactive videos and animation to attract more audiences. So, when Vue.js is offering these interactive features, it would be foolish not to make good use of them. It allows the usage of entering, leaving, state, and list transitions.

The tools can perform the following functions:

  • Automatic application of classes transitions and animations using CSS
  • Integration of third party CSS animation libraries like Animate.css
  • Directly driving the DOM during transition hooks by using JavaScript
  • Integration of third party animation libraries using JavaScript like Velocity.js
  • Using transitions and animations together at once using the "type" attribute
  • Specification of custom transition classes with "enter" and "leave" attributes

One can also add third-party animated libraries to the application for a more appealing user interface. While bringing in a new element from the DOM, Vue.js lets the developer use the transition in several ways, including:

  • Conditional rendering
  • Conditional display
  • Dynamic components
  • Component root nodes

Declarative Rendering For Virtual DOM:

The core system of Vue.js lets the user declaratively render data to the DOM, using straightforward template syntax without much hassle. This may look like rendering a string template, but that is because Vue.js has now linked the data and the Document Object Model (DOM). This has resulted in everything becoming reactive as now the JavaScript console in one's browser changes according to the value set to it.

Since the developer does not have to interact with the HTML directly, the changes made while developing the app will not instantly reflect on DOM. A Vue app that immediately pairs up with a single DOM element produces an imitation of DOM. This is usually present in custom JS data structures, and this new pseudo-app controls the original app entirely. Keeping the original HTML intact, all the new changes take place within the brand new Vue instance.

This virtual DOM allows the developer to run a test design and observe the changes done in the UI design. Yet, they have the relaxation to go back and undo all the changes and return to the original hypertext without losing anything.

Vue.js can also bind element attributes besides working on text interpolation. This lets the developers improvise on the style using v-bind, a set of data binding directives. It can easily help set values to HTML elements. The best thing about Vue.js is that it binds data to text and attributes and the structure of the DOM.

Composition With Single-file Components:

The component system is an integral part of Vue.js development since it is instrumental in allowing the developers to build large-scale applications from small, self-contained components. These components can be written in CSS, JavaScript, and HTML but do not need to be separated into discrete files. They are the captured elements of the application interface - thus, the component system is an abstraction of a tree of components.

The component is basically a Vue instance that has options that have been defined already. This method of dividing the code is an architectural method known as component-based architecture (CBA). Some of the advantages of this architecture are:

  • Unit-testing is supported by a QA movement that evaluates the way in which even the smallest parts of the app can function by themselves. These components help to streamline different tasks, managing all of which at once might be difficult.
  • The code is comparatively easier to read and understand as the components are kept in separate, singular files. Such a good management strategy is really helpful.
  • Captured components can be reused as they make up the codebase. They can function as templates wherever they are needed in the system.

With Vue.js, the developer can perform the following tasks:

  • Registering the component
  • Composing the component in another component's template
  • Adding custom attributes to components and decoupling them
  • Passing the custom attribute to every repeated component using v-bind

A Large Ecosystem:

The tooling ecosystem of Vue.js is robust and enriched. It has a wide range of tools for the developer to use. The contributors rewrote the entire Vue CLI 3 to deliver a lot of novel functions.

Vue.js supports end-to-end testing tools, TypeScript and Babel, and a plugin installation system. It also supplies the programmers with unit testing. Furthermore, the server renderer, state manager, and browser debugging tools work seamlessly in Vue.js.

The core library has the following tools and libraries:

  • Vue CLI for rapid Vue.js development
  • Devtools for debugging applications made with Vue.js
  • Vue Loader for permitting the writing of Single-File Components (SFCs) - a format of writing Vue components
  • Vue Router for conducting the official routing of the framework
  • Vuex for Centralized State Management of Vue.js, which has been inspired by Flux
  • Vue Server Renderer for the server-side activities of Vue.js

This JavaScript framework can support the integration of both existing server-rendered (multi-page) apps and single-page apps. The feature of unified integration with the newly developed app is a great opportunity offered by Vue. It connects the new app with the other popular web frameworks like Express, Laravel, and Rails.

Excellent Routing:

The inability to share links to a specific "sub" page within another webpage has always been a problem for SPAs. To solve this problem, many routers on the client-side used to delimit these connecting URLs with a "hashbang" (#!). But with the advent of HTML5, most browsers now allow routing without hashbangs.

In this situation, the Vue interface allows the developers to modify the webpage display depending on the current URL path. This does not take into account the way it was changed. This front-end router allows the intentional transition of the browser path when the buttons or links are clicked.

Front-end hashed routing is not included with Vue.js. But with the help of the Vue-router package, an API can be used to update the application's link, activate the back button, and reset email and passwords or send links to verify emails that require authentication. Mapping nested routes to nested components are made easier with Vue, especially with fine-grained transition control.

Extensive Documentation:

For an open-source framework to perform well amongst other developers, extensive documentation on the part of the web app development services is necessary. It lets the developer know the best practices of the framework and how to apply them properly. A framework must grow with the passing of time, making it successful in the long run.

Vue.js has very detailed documentation, which is continuously updated to keep up with technological advances. An overview of the API and an introductory guide in simple language is the major contribution of the documentation to get one started with Vue.js. As the programmer progresses and goes on to the more complex stages, the outlined instructions about more detailed aspects like scaling and reactivity become important.

Facilitating Hassle-free Customization:

Vue.js is an open-source framework, which means all its services can be accessed for free. To use the framework easily and wisely, the developers are allowed to name the functions as they wish. This makes the deployment and development processes faster as the discrete function of every piece can be modified easily as and when required.

Fastest Framework:

Vuejs frameworks are extremely fast. In fact, according to a Devtechnosys survey held in 2020, Vue.js was said to be one of the fastest frameworks. Even then, Vue.js can offer a smooth user experience in SPAs and UIs and not compromise its quality under any conditions. Thus, it's not surprising that top web applications like Reuters, Grammarly, Alibaba, Xiaomi, and Laracasts use Vue.js.

New research by Google states that 53% of visitors will leave a webpage if it doesn't load within three seconds. According to recent trends, the virtual world is shifting towards a mobile-first experience. At this point, the speed of Vue.js in building and launching apps is a serious advantage.


Vuejs frameworks are one of the most trusted frameworks in recent times. The quick performance time with a high-quality user experience sets Vue.js apart from the rest of the frameworks. Useful features along with extensive documentation and helpful community will help to keep this framework among the top rankings for a long time ahead.
