  • Storybook will auto generate documentation for Props, Events, Methods, Slots, Shadow Parts and Custom Properties.
  • Storybook doc page will contain stencils component documentation (readme.md or inline)

Installation

npm i -D @astrouxds/storybook-addon-docs-stencil

Usage

Configure stencil to generate docs-json at build time.

// stencil.config.ts

import { Config } from '@stencil/core';

export const config: Config = {
  outputTargets: [
    {
      type: 'docs-json',
      file: 'path/to/docs.json'
    }
  ]
};

Configure Storybook

//.storybook/main.js

module.exports = {
  addons: [
    '@storybook/addon-essentials',
    '@astrouxds/storybook-addon-docs-stencil'
  ]
}
//.storybook/preview.js

import { setStencilDocJson } from '@astrouxds/storybook-addon-docs-stencil';
import docJson from 'path/to/docs.json';
if(docJson) setStencilDocJson(docJson);

export const parameters = {
  controls: { hideNoControlsWarning: true }
}

Component documentation

readme.md

If not already created by stencil create src/components/my-component/readme.md If the line <!-- Auto Generated Below --> is not present, stencil will ignore this file.

Everything above this line will be included in storybook

<!-- Auto Generated Below -->

inline documentation

// src/components/my-component/my-component.tsx`

/**
 * Everything written here will be included, if readme.md is not present.
 */
@Component({
  tag: 'my-component',
  styleUrl: 'my-component.css',
  shadow: true,
})

Troubleshooting

When using @storybook/web-components

@storybook/web-components overrides the preset configuration of this module. You can fix this with this preview config.

//.storybook/preview.js

import { extractArgTypes, extractComponentDescription, setStencilDocJson } from '@astrouxds/storybook-addon-docs-stencil';

export const parameters = {
  ...
  docs: {
    extractArgTypes,
    extractComponentDescription,
  },
};
Hint your component in your stories
// your-story.ts

export default {
  title: 'My Component',
  component: 'my-component',
};
