paperthin

A small helper to create a React friendly component that uses a Web Component under the hood.

Usage

To create a React wrapper of a Web Component simply use the createWrapper helper of paperthin.

Basic

import { forwardRef } from 'react'
import { createWrapper } from '@catastic/paperthin'
// The props interface
import type { WebComponentProps } from 'some/model/file'
// The Web Component class
import type { WebComponentClazz } from 'some/file'
// The Web Component tag name
import { WebComponentTag as tagName } from 'some/model/file'

// The proper props
type ReactProps = HTMLAttributes<WebComponentProps>

export const ReactComponentWithChildrenWrapper = forwardRef<
  WebComponentClazz | null,
  ReactProps
>((props, ref) => createWrapper<WebComponentClazz>({ tagName, props, ref }))

// Alternatively, if your component has a default slot, you can pass `children` along
export const ReactComponentWrapper = forwardRef<
  WebComponentClazz | null,
  ReactProps
>(({ children, ...props }, ref) =>
  createWrapper<WebComponentClazz>({ tagName, children, props, ref })
)

Work with slotted elements

On top of the default slot, you can also forward ReactElement props to actual slot elements with the help of the slottedNode helper function.

export const ReactComponentWrapper = forwardRef<
  WebComponentClazz | null,
  ReactProps
>(({ emoji, children, ...props }, ref) =>
  createWrapper<WebComponentClazz>({
    tagName,
    props,
    children: (
      <>
        {children}
        {emoji && slottedNode(emoji, 'emoji')}
      </>
    ),
    ref,
  })
)
