Info addon for Vue components

storybook-addon-vue-info

A Storybook addon that shows Vue component's information.

• Demo

Requirements

• @storybook/vue>=4.0.0

Getting started

First, install the addon.

npm install --save-dev storybook-addon-vue-info

# yarn add -D storybook-addon-vue-info

Then register in addons.js.

// .storybook/addons.js

// Don't forget "/lib/" !!
import 'storybook-addon-vue-info/lib/register'

And setup custom webpack loader in order to extract component information with vue-docgen-api.

// .storybook/webpack.config.js

// This example uses "Full control mode + default".
// If you are using other mode, add payload of `config.module.rules.push` to rules list.
module.exports = ({ config }) => {
  config.module.rules.push({
    test: /\.vue$/,
    loader: 'storybook-addon-vue-info/loader',
    enforce: 'post'
  })

  return config
}

Usage

Add withInfo decorator then set info options to the story.

NOTE: info option is required for the addon. If you omit it, the addon does nothing.

import { storiesOf } from '@storybook/vue'

import { withInfo } from 'storybook-addon-vue-info'

storiesOf('MyComponent', module)
  .addDecorator(withInfo)
  .add(
    'foo',
    () => ({
      components: { MyAwesomeComponent },
      template: '<my-awesome-component/>'
    }),
    {
      info: {
        summary: 'Summary for MyComponent'
      }
    }
  )

You can set the addon as global decorator.

// config.js
import { addDecorator } from '@storybook/vue'

import { withInfo } from 'storybook-addon-vue-info'

addDecorator(withInfo)

To set default options, use setDefaults.

// .storybook/config.js
import { setDefaults } from 'storybook-addon-vue-info'

setDefaults({
  header: false
})

For more details, see live examples.

Options

Name	Data type	Default value	Description
header	boolean	true	Whether to show header or not.
source	boolean	true	Whether to show source(usage) or not.
wrapperComponent	Component	default wrapper	Override inline docs component.
previewClassName	string	undefined	Class name passed down to preview container.
previewStyle	Style object	undefined	Style passed down to preview container.
summary	string	''	Summary for the story. Accepts Markdown.

docsInPanel	boolean	true	Whether to show docs in addon panel.
useDocgen	boolean	true	Whether to use result of vue-docgen-api.

In addition to addon options, we have a component option.

propsDescription

If you want to explicitly specify desciprion for component props, add propsDescription option for your story component.

Assume <my-awesome-component> have props label and visible.

storiesOf('MyComponent', module)
  .addDecorator(withInfo)
  .add(
    'foo',
    () => ({
      components: { MyAwesomeComponent },
      template: '<my-awesome-component/>',
      propsDescription: {
        MyAwesomeComponent: {
          // These description will appear in `description` column in props table
          label: 'A label for my awesome component',
          visible: 'Whether component is visible or not'
        }
      }
    }),
    {
      info: true
    }
  )

Loader options

You can pass options for vue-docgen-api through loader options (e.g. module alias).

// .storybook/webpack.config.js

module.exports = ({ config }) => {
  config.module.rules.push({
    test: /\.vue$/,
    loader: 'storybook-addon-vue-info/loader',
    options: {
      docgenOptions: {
        // options for vue-docgen-api...
      }
    },
    enforce: 'post'
  })

  return config
}
