@public-ui/stencil-react-output-target

Stencil can generate React class component wrappers for your web components. This allows your Stencil components to be used within a React application. The benefits of using Stencil's component wrappers over the standard web components include:

Typings for your components
JSX bindings for custom events (event names are renamed to match React's convention of onEventName)
Tag names are renamed to match PascalCase convention.
Adds support for property types outside of string and number (supports: functions, objects and arrays).

Installation

npm install @public-ui/stencil-react-output-target

Usage

In your stencil.config.ts add the following configuration to the outputTargets section:

import { Config } from '@stencil/core';
import { reactOutputTarget } from '@public-ui/stencil-react-output-target';

export const config: Config = {
  namespace: 'demo',
  outputTargets: [
    reactOutputTarget({
      componentCorePackage: 'component-library',
      proxiesFile: '../component-library-react/src/components.ts',
    }),
    {
      type: 'dist',
      esmLoaderPath: '../loader',
    },
  ],
};

Config Options

Property	Description
`componentCorePackage`	The NPM package name of your Stencil component library. This package is used as a dependency for your React wrappers.
`proxiesFile`	The output file of all the component wrappers generated by the output target. This file path should point to a location within your React library/project.
`excludeComponents`	An array of tag names to exclude from generating component wrappers for. This is helpful when have a custom framework implementation of a specific component or need to extend the base component wrapper behavior.
`loaderDir`	This is the path to where the `defineCustomElements` function exists in your built project. If `loaderDir` is not provided, the `/dist/loader` directory will be used.
`includePolyfills`	If `true`, polyfills will automatically be imported and the `applyPolyfills` function will be called in your proxies file. This can only be used when lazy loading Web Components and will not work when `includeImportCustomElements` is `true`.
`includeDefineCustomElements`	If `true`, all Web Components will automatically be registered with the Custom Elements Registry. This can only be used when lazy loading Web Components and will not work when `includeImportCustomElements` is `true`.
`includeImportCustomElements`	If `true`, the output target will import the custom element instance and register it with the Custom Elements Registry when the component is imported inside of a user's app. This can only be used with the Custom Elements Bundle and will not work with lazy loaded components.
`customElementsDir`	This is the directory where the custom elements are imported from when using the Custom Elements Bundle. Defaults to the `components` directory. Only applies when `includeImportCustomElements` is `true`.

Runtime Config Options

If you want to use custom tag names, you can use the setTagNameTransformer function to define a function which transforms the tag names.
It is recommended to configure this before you use the component library.

import { setTagNameTransformer } from '<your-library>/react';
setTagNameTransformer((tagName: string) => `${tagName}-v2`);
