React vs Vue – the best Javascript UI library

Vue and React are two frontend JavaScript frameworks that are widely popular. React undoubtedly has the top spot for many years, Vue also has its own advantages depending upon the application and its usability.

Choose the best JavaScript UI library as per your application’s usecase:

1. For building Apps with templates, choose Vue

Putting your markup in an HTML file is the default option for a Vue app. Directives or special HTML attributes adds functionality to the template. React apps avoid templates and expect the developer to create their DOM in JavaScript, typically aided with JSX. For templates, it is necessary to learn all the extended HTML syntax. Render functions only require knowledge of standard HTML and JavaScript. Render functions also have the benefit of easier debugging and testing.

Advantages of JSX:

In React components express their UI within render functions using JSX, a declarative XML-like syntax that works within JavaScript. Render functions with JSX have advantages of building a better view since we can leverage the power of JavaScript. This includes temporary variables, flow controls, and directly referencing JavaScript values in scope.

The tooling support (e.g., linting, type checking, editor autocompletion) for JSX is more advanced than what’s currently available for Vue templates.

Advantages of HTML templates:

Any valid HTML is also a valid Vue template, and this leads to a few advantages of its own:

  • For developers who are much familiar with HTML, templates are easier to read and write.
  • HTML-based templates make it much easier to progressively migrate existing applications to take advantage of Vue’s reactivity features.
  • It also makes it much easier for designers and less experienced developers to parse and contribute to the codebase.
  • Use pre-processors such as Pug to author your Vue templates.

Take a look at this comparison of an application in React and Vue using templates.

Vue:

<div id="app">
<p>{{ message }}</p>
<button v-on:click="reverseMessage">Reverse Message</button>
</div>
new Vue({
el: '#app',
data: {
message: 'Hello Vue.js!
},
methods: {
reverseMessage: function () {
this.message = this.message.split('').reverse().join('');
}
}
});

React requires developer to create their DOM in JavaScript aided with JSX usually.

<div id="app"></div>
class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      message: 'Hello React.js!'
    };
  }
  reverseMessage() {
    this.setState({ 
      message: this.state.message.split('').reverse().join('') 
    });
  }
  render() {
    return (
      <div>
        <p>{this.state.message}</p>
        <button onClick={() => this.reverseMessage()}>
          Reverse Message
        </button>
      </div>
    )
  }
}
ReactDOM.render(App, document.getElementById('app'));

2.For building large scalable apps, and the biggest ecosystem – choose React.

Template based apps that re used more in Vue are easier to understand, quicker to get up and running. Which might give an impression of scalability, but these benefits take a toll on the scalability of Vue apps. Templates are prone to unnoticed runtime errors, are hard to test, and are not easy to restructure or decompose. In contrast, JavaScript-templates can be organized into components with nicely decomposed and DRY code that is more reusable and testable.

Vue also has a component system and render functions. But React’s rendering system has configurability, it also has shallow rendering. Combining shallow rendering with React’s testing utilities allow for testable and maintainable code.

Meanwhile, React’s immutable application data may not be as succinct, but it shines in a larger application when transparency and testability become critical.

When it comes to the ecosystem of developers using these frameworks, React is more popular library with ~2.5M NPM downloads a month as opposed to Vue’s ~225K per month.

Summing up,

React and Vue share a lot of similarities in their operation than any other prominent JS frameworks.

Similarities between React and Vue:

  • Utilize a virtual DOM
  • Easy integration with router, bundler, and state management
  • Provide reactive and composable view components
  • Focused in the core library, with concerns such as routing and global state management handled by companion libraries.
  • Fast rendering using virtual DOM
  • Lightweight JS frameworks
  • Reactive components
  • Server-side rendering
  • Great support and community

Here are a few Advantages of Vue over React:

  • Flexible choices for template or render functions.
  • Not complex in syntax and project setup.
  • Faster rendering and smaller size.

Here are the major advantages of React over Vue:

  • Better at scale, sturdier, and more testable
  • Web and native apps
  • A bigger ecosystem with more support and tools available
