To ease the frontend development there are lots of frameworks and libraries that help in simplifying the process of building interactive and dynamic user interfaces. React, lit-element, and lit-html are three popular choices, each with its own set of features, advantages, and use cases. In this article, we will learn more about them that help you choose the right framework/library for your application.
1. React
React is one of the most popular, efficient, and powerful open-source JavaScript libraries for building dynamic and interactive user interfaces. ReactJS is famous for its component-based architecture and virtual DOM which makes it highly efficient in rendering user interface and ensuring optimal performance. Due to its reusable components, It is very helpful in the efficient development and maintenance of large-scale applications.
ReactJS has a vast ecosystem and community which makes the development very easy and ensures performance optimization. ReactJS is not a framework, it is just a library developed by Facebook.
Syntax:
class MyComponent extends React.Component {
render() {
return (
/ / JSX code here
);
}
}
Features of React:
- JavaScript Library: Open-source library advanced by using Facebook.
- User Interface Building: Used for constructing dynamic and interactive user interfaces in applications.
- Component-Based: Allows you to create reusable UI components for modular improvement.
- Virtual DOM: Optimizes rendering via the usage of a virtual representation of the DOM i.e virtual DOM.
- Declarative Syntax: Describes the support UI outcome, simplifying code and rebuilding.
- Efficient State Management: Provides mechanisms for managing issue domain correctly.
- Unidirectional Data Flow: Data updates in a single direction, assist traceability and information.
Example:
Open your terminal or command prompt and run the following command to create a new React project:
npx create-react-app hello-world-react//App.js
import React from 'react';
class HelloWorldReact extends React.Component {
render() {
return (
<div>
<h1>Hello, World!(React) < /h1>
< /div>
);
}
}
export default HelloWorldReact;
Run the application by using the following command:
npm startOutput:
Rendering a simple 'Hello, World!' component using React.
2. LitElement
lit-element is a lightweight library for building web components using modern JavaScript features such as template literals and custom elements. It is developed by the Polymer Project.
Syntax:
class MyElement extends LitElement {
static styles = CSS
// CSS styles here
;
render() {
return html // HTML template here ;
}
}
Features of LitElement:
- Web Components: lit-element is built on top of web components, a set of web platform APIs that allow for the creation of reusable custom elements.
- Declarative Templating: lit-element provides template literals, enabling you to write declarative HTML templates directly within JavaScript code.
- Efficient Rendering: lit-element automatically updates the DOM when component properties change, ensuring efficient rendering and optimal performance.
- CSS Shadow Parts: lit-element provides support for CSS Shadow Parts, allowing you to style nested elements within a component's shadow DOM.
Example:
Create a file named index.html inside your project directory and download Live Server extension. Copy the following code into index.html, save it, and click on "go live". You will be able to see the output on the browser.
<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>LitElement Example</title>
<!-- Import LitElement library -->
<script type="module"
src="https://cdn.jsdelivr.net/gh/lit/dist@2/core/lit-core.min.js"></script>
</head>
<body>
<script type="module">
import { LitElement, html, css }
from 'https://cdn.jsdelivr.net/gh/lit/dist@2/core/lit-core.min.js';
class HelloWorldLitElement extends LitElement {
static styles = css`
:host {
display: block;
}
`;
render() {
return html`
<div>
<h1>Hello, World! (LitElement)</h1>
</div>
`;
}
}
customElements.define('hello-world-lit-element',
HelloWorldLitElement);
</script>
<!-- Render LitElement component -->
<hello-world-lit-element>
</hello-world-lit-element>
</body>
</html>
Output:
Rendering a simple 'Hello, World!' component using LitElement.
3. LitHTML
LitHTML, an HTML template library, provides dynamic HTML generation using JavaScript template literals. It provides concise syntax and efficient DOM updates, making it suitable for lightweight projects focusing on efficient templating and minimal overhead.
Syntax:
const myTemplate = (name) => html`
// HTML template here
;
Features of LitHTML:
- HTML Templating: lit-html provides a simple way to generate HTML templates using JavaScript template literals.
- Efficient Updating: lit-html efficiently updates the DOM by only modifying parts of the DOM that have changed, resulting in fast rendering and minimal overhead.
- Data Binding: lit-html supports data binding, allowing developers to bind data from JavaScript to HTML templates and automatically update the UI when the data changes.
- Directives: lit-html introduces directives, special attributes that modify the behavior of template expressions, providing flexibility and control over the rendering process.
Example:
Create a file named index.html inside your project directory and download Live Server extension. Copy the following code into index.html, save it, and click on "go live". You will be able to see the output on the browser.
<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>HelloWorldLitHtml</title>
<script type="module">
import { html, css, LitElement }
from 'https://cdn.jsdelivr.net/gh/lit/dist@2/core/lit-core.min.js';
class HelloWorldLitHtml extends LitElement {
static styles = css`
:host {
display: block;
}
`;
render() {
return html`
<div>
<h1>Hello, World! (lit-html)</h1>
</div>
`;
}
}
customElements.define('hello-world-lit-html',
HelloWorldLitHtml);
</script>
</head>
<body>
<hello-world-lit-html>
</hello-world-lit-html>
</body>
</html>
Output:
Rendering a simple 'Hello, World!' component using LitHTML
Differences between React, LitElement and LitHTML:
React | LitElement | LitHTML |
|---|---|---|
Class-based components with lifecycle hooks for state management and rendering. | Uses ES6 classes for defining custom elements, promoting encapsulation and reusability. | Relies on JavaScript template literals for concise and efficient HTML template creation. |
Uses JSX for HTML-like syntax within JavaScript for defining component UIs. | Utilizes template literals for clear and expressive component template definition. | Utilizes JavaScript template literals for dynamic HTML generation. |
Optimizes rendering through virtual DOM diffing, updating only changed parts of the DOM. | Offers efficient rendering and updates through LitHTML, ensuring optimal performance. | Ensures efficient rendering and updates for dynamic HTML templates, minimizing overhead. |
Large ecosystem with extensive community support. | Growing ecosystem with support from Google. | Growing ecosystem with support from Google. |
Moderate to steep learning curve due to its class-based and functional based approach. | Moderate learning curve with modern JavaScript features. | Low learning curve with straightforward template literals. |

Conclusion:
React, lit-element, and lit-html are three powerful choices for frontend development, each with its own strengths and use cases. React is excellent for building large-scale applications with complex UIs, while lit-element and lit-html are well-suited for building web components and lightweight applications. The choice between these technologies depends on the specific requirements of your project, your familiarity with the technology stack, and the preferences of your development team.
