As web development is becoming more complex day by day, the importance of frontend frameworks and libraries is increasing too. With the help of these libraries, developers can optimize the frontend performance of their web applications. Below are the top 10 frontend frameworks and libraries that developers should know about in 2021:
ReactJS is a popular and widely-used JavaScript library for building user interfaces. Developed by Facebook, ReactJS has a strong following and community. The goal of ReactJS is to be fast, simple, and scalable. With ReactJS, developers can create reusable components that enable them to create complex user interfaces with ease. ReactJS also has an excellent developer experience as it provides tools like React Developer Tools, a debugging and profiling tool.
import React from 'react';
function App() {
return (
<div>
<h1>Hello World!</h1>
</div>
);
}
export default App;
Developed by Google, Angular is a popular and highly scalable frontend framework for building complex applications. Angular provides a complete set of fully-featured tools, including a powerful CLI, that makes the whole development process simple and efficient. Angular also offers a range of features such as reactive programming, dependency injection, and tree shaking.
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: '<h1>{{title}}</h1>',
})
export class AppComponent {
title = 'Hello World!';
}
VueJS is a progressive JavaScript framework for building user interfaces. Known for its simplicity and elegant design, VueJS has a flexible and easy to learn syntax that makes it a popular choice amongst developers. VueJS offers features like reactive data binding, a virtual DOM, and a powerful template system.
<template>
<div>
<h1>{{ title }}</h1>
</div>
</template>
<script>
export default {
data() {
return {
title: 'Hello World!'
};
}
};
</script>
Ember is a frontend framework for building complex web applications. Ember includes several features that make it a popular choice amongst developers. Ember offers out of the box support for routing, controllers, and models, which make it effortless for developers to create complex applications. Ember also provides a robust and class-based component system that makes it easy to create reusable UI components.
import Ember from 'ember';
export default Ember.Component.extend({
actions: {
sayHello() {
alert('Hello World!');
}
}
});
Svelte is a relatively new JavaScript framework that aims to make the process of building user interfaces simple and efficient. Svelte compiles your code at build time, which means that it eliminates the need for a runtime library, making it a faster and more lightweight option. Svelte's syntax is also straightforward and easy to use, and it provides an excellent developer experience.
<script>
let name = 'World';
</script>
<h1>Hello {name}!</h1>
Backbone is a popular JavaScript library that provides a minimalist framework for building web applications. Backbone's simplicity and flexibility make it a popular choice amongst developers. With Backbone, developers can create scalable applications with ease, and the library includes features like models, events, and collections that make it a complete solution for web development.
var Todo = Backbone.Model.extend({
defaults: {
title: '',
completed: false
}
});
var todo = new Todo({
title: 'Learn Backbone'
});
console.log(todo.toJSON());
Aurelia is a modern frontend framework that is designed to make the process of building web applications more comfortable and more efficient. It is a complete solution that includes features like dependency injection, routing, and components. Aurelia's design is also made to be highly composable, which makes it easy to integrate with other libraries and frameworks.
import { customElement, bindable } from 'aurelia-framework';
@customElement('hello-world')
export class HelloWorld {
@bindable name;
onClick() {
alert(`Hello, ${this.name}`);
}
}
RiotJS is a lightweight and simple-to-use frontend library. With RiotJS, developers can create reusable web components with a minimum amount of code. RiotJS follows the web standards and is highly composable, which makes it easy to integrate with other libraries.
<hello-world>
<h1>Hello { props.name }!</h1>
<button onclick={ props.onClick }>Say hello</button>
</hello-world>
StencilJS is a modern and efficient frontend library that is designed to make it easier to create web components. StencilJS provides features like virtual DOM and SSR that makes it highly performant. It also makes it easy to create reusable components and integrate them with other libraries and frameworks.
<my-component name="World"></my-component>
<script>
class MyComponent {
render() {
return `<h1>Hello ${this.name}!</h1>`;
}
}
customElements.define('my-component', MyComponent);
</script>
Polymer is a modern and powerful library that makes it easy to create modular and scalable web components. With Polymer, developers can create complex applications with ease and efficiency. Polymer provides features like data binding and custom elements that make it an excellent choice for web development.
<dom-module id="hello-world">
<template>
<h1>Hello {{name}}!</h1>
</template>
<script>
Polymer({
is: 'hello-world',
properties: {
name: {
type: String,
value: 'World'
}
}
});
</script>
</dom-module>
With the increasing complexity of web applications, frontend developers often face the challenge of optimizing the performance of their applications. Frontend frameworks and libraries can help to optimize performance in several ways:
Frontend frameworks and libraries provide developers with an array of tools that make it easier to build high-performing web applications. By using these tools, developers can optimize the performance of their applications and provide a better user experience for their users.
Frontend frameworks and libraries are crucial tools for developers in 2021. The ever-increasing complexity of web applications has made it necessary for developers to use these tools to build scalable and high-performing applications. The frontend frameworks and libraries we have discussed above provide an array of features and tools that enable developers to optimize the performance of their applications. By using these tools, developers can create efficient and high-performing web applications that provide a better user experience for their users.
