Piral Preact ·

This is a plugin that only has a peer dependency to preact. What piral-preact brings to the table is a set of Pilet API extensions that can be used with piral or piral-core.

The set includes a Preact converter for any component registration, as well as a fromPreact shortcut and a PreactExtension component.

By default, these API extensions are not integrated in piral, so you'd need to add them to your Piral instance.

Documentation

The following functions are brought to the Pilet API.

fromPreact()

Transforms a standard Preact component into a component that can be used in Piral, essentially wrapping it with a reference to the corresponding converter.

PreactExtension

The extension slot component to be used in Preact component.

Usage

::: summary: For pilet authors

You can use the fromPreact function from the Pilet API to convert your Preact components to components usable by your Piral instance.

Example use:

import { PiletApi } from '<name-of-piral-instance>';
import { PreactPage } from './PreactPage';

export function setup(piral: PiletApi) {
  piral.registerPage('/sample', piral.fromPreact(PreactPage));
}

Within Preact components the Piral Preact extension component can be used by referring to PreactExtension, e.g.,

<PreactExtension name="name-of-extension" />

Alternatively, if piral-preact has not been added to the Piral instance you can install and use the package also from a pilet directly.

import { PiletApi } from '<name-of-piral-instance>';
import { fromPreact } from 'piral-preact/convert';
import { PreactPage } from './PreactPage';

export function setup(piral: PiletApi) {
  piral.registerPage('/sample', fromPreact(PreactPage));
}

::: summary: For Piral instance developers

Using Preact with Piral is as simple as installing piral-preact and preact@^10.

import { createPreactApi } from 'piral-preact';

The integration looks like:

const instance = createInstance({
  // important part
  plugins: [createPreactApi()],
  // ...
});

The preact package should be shared with the pilets via the package.json:

{
  "importmap": {
    "imports": {
      "preact": ""
    }
  }
}
