Do you have an awesome Svelte 3 component you would like to use within your React app? If so, you've come to the right place!

React-Svelte3-Adapter

Installation

yarn add react-svelte3-adapter

or

npm install --save react-svelte3-adapter

Usage

Basic example

import React, {useState} from 'react';
import SvelteAdapter from 'react-svelte3-adapter';
import SomeSvelte3Component from 'some-svelte3-library';

export function MyReactComponent() {
    const [name, setName] = useState('World');
  return (
    <React.Fragment>
        <input type='text' value={name} onChange={(e) => setName(e.target.value)}/>
        {/*Any change in name will be passed to the svelte component*/}
        {/*Every time the svelte component emits an event with the name "someevent" the function will be called */}
        <SvelteAdapter
            svelteComponent={SomeSvelte3Component}
            data={{name}}
            listeners={{someevent: (e) => alert(JSON.stringify(e.detail))}}
        />
    </React.Fragment>
  );
}

Available Props

SvelteAdapter.propTypes = {
    /** The svelte component to wrap. Doesn't change after initialization.
     * Needs to be compiled with the 'generate:dom' option (which is the svelte default).
     */
    svelteComponent: PropTypes.func.isRequired,

    /** Passed into the svelte component as props. */
    data: PropTypes.object.isRequired,

    /** An object that maps event-names to handler functions.
     * When the svelte component emits the event, the handler will be called.
     */
    listeners: PropTypes.objectOf(PropTypes.func),
    
    /** A class to add to the div that the svelte component mounts to (a.k.a it's container).*/
    containerClass: PropTypes.string,
    
    /** Inline containerStyles to add to the div that the svelte component mounts to (a.k.a it's container).*/
    containerStyles: PropTypes.objectOf(PropTypes.string)
};

Misc

• If you would like to create a sharable svelte3 component you can then use this component to wrap, this repo will get you going. Just make sure you use the default compilation target (generate:dom).
• At the time of writing these lines and to the best of my knowledge, other npm modules that have the same functionality as this one only work with Svelte 2, including the official one.
