React to Web Component
@r2wc/react-to-web-component is a fascinating tool that bridges the gap between React, a popular JavaScript library for building user interfaces, and web components, which are reusable HTML elements. By utilizing this tool, developers can convert their React components into custom HTML elements that can be used with any project, regardless of the framework—be it Vue, Svelte, Angular, or others—without the need for React to mount them.
Key Features
- Broad Compatibility: It works seamlessly in all modern browsers. However, Internet Explorer users may need a customElements polyfill.
- Compact Size: The package is just 1.26KB when minified and gzipped, ensuring efficiency without bloat.
Setup
Getting started is a breeze. Simply install it from npm:
npm install @r2wc/react-to-web-component
Support and Assistance
Should you need any help or have questions, Bitovi, a React consultancy, offers a range of support options. You can connect via their Discord Community or Twitter, and if preferred, they also offer training, consulting, and development services with free consultations available.
Basic Usage
To illustrate basic usage, consider a simple React component:
const Greeting = () => {
return <h1>Hello, World!</h1>
}
After creating the React component, use r2wc along with customElements.define to transform it into a custom element:
import r2wc from "@r2wc/react-to-web-component"
const WebGreeting = r2wc(Greeting)
customElements.define("web-greeting", WebGreeting)
This allows <web-greeting> to be used just like any other standard HTML element in a webpage.
<body>
<web-greeting></web-greeting>
</body>
Working with Attributes
Custom elements by r2wc focus on passing properties to React components. To utilize HTML attributes, specify prop types:
const Greeting = ({ name }) => {
return <h1>Hello, {name}!</h1>
}
const WebGreeting = r2wc(Greeting, {
props: {
name: "string",
},
})
This setup allows for:
<body>
<web-greeting name="Justin"></web-greeting>
</body>
For more complex scenarios, there's guidance for programmatic usage and additional demos available.

How It Works
R2WC operates by creating a CustomElementConstructor. With custom getters, setters, and lifecycle methods, it tracks and manages props effectively. Each property adjustment re-renders the underlying React component, utilizing enumerable properties and values.
The React component remains dormant until the custom element is loaded into the page, optimizing performance.
