Getting Started

Install it:

cd my-project
npm install --save-dev vue-play vue-play-cli
# vue-play-cli gives you the `vue-play` command
# vue-play is the UI utils.

Add npm scripts:

{
  "scripts": {
    "play": "vue-play start",
    "play:build": "vue-play build"
  }
}

Write play entry to load your examples:

// ./play/index.js
import { play } from 'vue-play'
import MyButton from './components/MyButton.vue'

play('Button')
  .add('with text', h => h(MyButton, 'hello'))
  .add('with emoji', h => h(MyButton, '💫'))

Then just run npm run play and go to http://localhost:5000

For more usages on vue-play-cli, please head to vue-play/vue-play-cli.

The hard way

There're two pages in your play app, one is the app interface which has a sidebar and it can toggle scenarios of your components, the other page is for rendering the examples, this page will be loaded as iframe in app interface.

And only the latter needs to load scenarios that you write in the play entry, let's say ./play/index.js:

import { play } from 'vue-play'
import MyButton from './MyButton.vue'

play('MyButton')
  .add('with text', h => h(MyButton, ['text']))

App interface

// ./play/app.js
import app from 'vue-play/app'

// bootstrap app
app()

Preview

// ./play/preview.js
import './' // which is ./play/index.js
import preview from 'vue-play/preview'

// actually render the scenarios in preview page
// when the preview page is ready
// it will tell the app interface what scenarios we have
preview()

Add app interface and preview to your webpack entry:

module.exports = {
  // ...
  entry: {
    app: './play/app.js',
    preview: './play/preview.js'
  },
  // don't forget to generate html output for both of them
  plugins: [
    new HtmlWebpackPlugin({
      filename: 'index.html',
      chunks: ['app']
    }),
    new HtmlWebpackPlugin({
      filename: 'preview.html',
      chunks: ['preview']
    })
  ]
}

That's it, you're all set!

Writing Scenarios

scenario, a.k.a. story in react-storybook, it's usually an example for demostrating your real component.

Keeping Scenarios

You can keep scenarios anywhere you want, for example you can keep them all at ./play/index.js, you can also use separate files for them, or even name them *.play.js in your component directory and load them dynamically.

Writing Scenarios

import { play } from 'vue-play'
import MyButton from '../src/components/MyButton.vue'

// Use `play` to describe component title
// use .add to add scenario for that component
play('MyButton')
  .add('with text', h => h(MyButton, ['hello world']))
  .add('with emoji', h => h(MyButton, ['😃🍻']))

Loading Scenarios Dynamically

We can use Webpack's require.context to load modules dynamically.

const load = requireContext => requireContext.keys().map(requireContext)

// load files which end with `.play.js` in `../src/components` folder
load(require.context('../src/components', true, /.play.js$/))

Register Components

If you are using render function you won't need to register components, you only need this when you are using the template property, and it's same way as you do in other Vue app:

// ./play/index.js
import Vue from 'vue'
import MyButton from './MyButton.vue'

// register globally
Vue.component('my-button', MyButton)

play('MyButton')
  .add('with text', {
    template: '<my-button>text</my-button>'
  })

You can also register components locally.

Use Component as play() argument

import MyButton from './MyButton.vue'

// assuming MyButton.name is 'my-button'
play(MyButton)
  // MyButton will be automatially registered in scenarios
  // so you don't have to register it again
  .add('with text', '<my-button></my-button>')

// then the app sidebar will look like:
// - my-button
//    - with text

To customize the displayName in sidebar and the componentName which is used to register itself in scenarios, you can simply set them in your component:

<!-- ./MyButton.vue -->
<script>
  export default {
    name: 'my-other-button',
    displayName: 'Show off my cute button'
  }
</script>

Or use methods:

play(MyButton)
  .name('my-other-button')
  .displayName('Show off my cute button')
  .add('with text', '<my-other-button>text</my-other-button>')

Component Shorthand

If you only need template or render property for your component, you can use component shorthand, which means you can directly set the value of scenario to a template string or render function:

import Example from './Example.vue'
play('Button')
  .add('template shorthand', '<my-button>text</my-button>')
  .add('render function shorthand', h => h(MyButton, ['text']))
  .add('full component', {
    data() {},
    methods: {},
    render(h) {}
    // ...
  }).
  .add('single file', Example)

note: If you are using template shorthand or template property in component options, you should use Vue standalone build as well. For vue-play-cli, it's as simple as using --standalone option.

Additional Component Properties

The component for each scenario is a typical Vue component, but it can also accept some additional properties for documenting its usage, eg:

play('Button')
  .add('with text', {
    // a valid vue component
    ...component,
    // additional
    example,
    // ...
  })

example

Type: string

The example code of your component.
