What Is Vue.Js: Comparison With React.Js And Angular.Js

Let’s recall what Vue.js is and why it is quickly rising among a lot of front-end development frameworks. Vue is an incredibly adaptable JavaScript web development technology that scales between a library and a complete framework. Its learning process is smooth, plus it is supplied with well-written documentation.

Efficiency is a key attribute of Vue due to its ultra-fast virtual DOM and smallest size out of all available frameworks. Vue fits for a big choice of web development projects and the decision of whether to implement it completely depends on the engineering team’s preferences and expectations.

One of the Vue.js development companies – Brights Team, successfully implements this framework on web projects in multiple domains. Besides Vue, there are other famous frameworks that construct full-featured, responsive, and modern UI for web apps. In this article, we will draw an analogy between Vue and other two frameworks, favored by developers worldwide — Angular.js and React.js.


Syntax and Learning

Our three chosen frameworks are built on JavaScript, a language, accepted by web browsers. The othernesses among systems appear on the grade of language syntax. Angular.js’s syntax is rather complex, based on TypeScript that is basically an isolated language, a superset of JavaScript. TypeScript offers many advanced functions and instruments for developers, being more profitable for more complicated projects. React.js applies its own syntax, JSX, or JavaScript XML, which signifies HTML structures and manages CSS through JavaScript.

Part of Vue’s syntax originated in Angular and underwent some improvements. Vue.js uses clear HTML, based on templates, requiring no conversions in order to be inserted into an HTML file. Out of three frameworks, Vue.js is the lightest to master. For someone with prior JS knowledge, it takes a short time to become aware of how to build a small application. As for Angular, the studying process is hard. React, compared to Angular, is lighter for understanding.


Both Angular and React allow designing scalable applications that can increase in scale and intricacy. Angular ensures scalability with its modular development composition, while React applies a component approach with identically impressive outcomes. Vue.js, unfortunately, is not so applicable to the construction of large apps.

Patterns that serve as a basis for Vue’s syntax become too sophisticated to reuse, as compared to JavaScript components, implemented by React and Angular.

DOM Model and UI Rendering

Web development frameworks can render pages of the apps on the client-side and on the server-side. Document Object Model is accountable for the content, design, and construct of HTML documents management. Each of the frameworks processes DOM differently and renders the document page, demonstrated to the user, differently.

Vue.js and React.js apply a Virtual DOM: create a copy of the real DOM, process it, compare with the original. Eventually, only those sections of the page that differ from the processing results are substituted on the user’s screen. Thus, the page loading and rendering happen quicker, plus traffic volume is reduced. Angular has another approach to document processing.

It uses the regular DOM, where the whole web page re-renders, when just the one element has been transfigured. The browser, or client part, initiates the DOM rendering, the server part creates directives, loads code, performs services, and renders the doc.

Component Architecture

Components and modules perform tasks with similar functionality, reducing the codebase size, and growing the processing speed. Angular, Vue, and React provide reactive and multiplex view elements. In Angular, the basic building blocks are NgModules, which suggest a compilation context for components.

The elements are reusable and superposed to generate a whole user interface. A modular architecture, like in Angular, is more fitting for the designing of complicated apps. While Angular has a strict view on how the application should be structured, Vue’s component-based architecture can offer a much more supple solution.

React also uses components as building blocks for UIs and provides all important instruments to determine what must be rendered and how. React doesn’t use any patterns. The component logic is built on JS that makes the app more flexible and streaming huge amounts of data via it, while aiding the status of the DOM.

Libraries Use

Angular.js and Vue.js are both complete frameworks, while React is a library, designed for MVC. United with some other tackles, React can become a “framework” too. Angular supplies programmers with the biggest amount of libraries and with a somewhat overwhelming amount of characteristics.

When React is implemented on the project, additional libraries are needed, for some specific tasks with a need to set up the functional part of the application for a certain library. Differences in libraries, as well as low-level APIs, require more time for configuration. Angular.js does not require searching for additional libraries or configuring them.

The high-level API provides mutual compatibility for all libraries. React requires bringing outside libraries sometimes even for common tasks, for example, form validation, routing, or operation with a Http-client. React though perfectly renders content to the DOM and effectively regulates it. Vue.js maintains concentration on the center library, allowing conjugate libraries to handle some functions.

Data Flow

React.js and Vue.js (generally) maintain data binding in one direction only, Angular.js sends data in both directions. Angular allows two-way data binding, where any modifications to the model influence the view; and when the view modifications, the model instantly varies in response.

One-way data binding, implemented in React, lets the view respond to any modifications in the model, while the model does not respond to the view change. One-directional data flow decreases the ability of side actions and provides more elementary reasoning in far-out applications. Although Vue.js does not permit two-way data binding betwixt parent and child, if needed, two-way binding can be achieved through the use of a v-model.

Framework Updates and Backward Compatibility

For Angular, a modern large release is produced every half year. React.js does not follow an exact update schedule, periodically making minor releases and adding completely new features, keeping the former ones. Vue also gets constant upgrades. Thus, modules and libraries are renewed regularly to all these technologies, but the approach to their integration process differs a lot.

In Angular.js, new versions depend on old ones and require the installation of all updates in-between. That inevitably leads to an increase in the application size. React has fully compatible versions. Their libraries can be united to the application with their established properties intact. Vue.js has a modular system, like React, that includes all the attributes of the JS framework, and operates with full backward compatibility.

Native Development

With all the mentioned frameworks, developers can create native apps for gadgets by connecting extra libraries. RN allows programmers to design native-rendered apps for iOS and Android, using the analogous React component sample.

Vue officially cooperates with Weex, which allows creating components for native rendering on iOS and Android, additionally to the rendering in the browser. As Weex is so far in dynamic development, an option like NativeScript-Vue, a NativeScript plugin allows creating native apps with the help of Vue.js. With Angular.js, SDK Ionic can be used for the idem purpose.

What Framework to Choose?

For some projects, Vue.js platform can offer a compromise between React.js and Angular.js. It’s not as “large” as Angular, but it doubtless provides more useful features for the designers than React. Just like Angular and React, the basis of Vue platform is a conjunction of reusable constituent elements for creation of user interfaces.

In a broad sense, it offers programmers more than React and less than Angular. If developers anticipate the application fine-tuning or update further, then Vue.js will be preferred. This framework allows programmers to vary the application without breaking its architecture. Vue is also a great decision for the draft with planned functionality expansion due to the excellent backward compatibility. As a bottom line, there is no prime framework or library.

All competitors are highly demanded for the obvious causes. All of them have pluses and minuses and the developers themselves decide, which project fits them best.
