Storybook ADK
Some of features originally introduced in this package are already available via Storybook API. Please consider https://github.com/storybookjs/addon-kit first, which is a simple Github repo template that uses the latest addon APIs.
This kit provides additional middleware for Storybook API and can be used for creating addons based on this.
Simplifies the addons creation. Keeps in sync addon's data through the channel. Provides intelligent blocks for creating addon UI. Offer simple API for registering addons and creating decorators. It's a base to quickly build your custom brand new awesome addon
Features
- Hides under the hood all the complex issues of communication through the channel and data synchronization while switching stories.
- Connects your addon components to your addon store via HOCs and updates it only when data changes
- Divides addon store data to global and local. Tracks story surfing in order to switch appropriate local data both on manager and preview sides simultaneously
- Keeps immutable init data and overridable data which you mutate via actions
- Provides redux like approach to deal with your addon store via selectors and actions (but don't worry, the default action just simply override your data)
- Allows to connect any amount of pannels, buttons and any other addon types to the single addon store
- Offers UI container which automatically reflects the aspect ratio of addon panel. Extremely useful to create addon UI responsive for vertical and horizontal panel positions
- Includes Typescript definitions
Usage
npm i --save @storybook/addon-devkit
import {
register,
createDecorator,
setParameters,
setConfig,
Layout,
Block,
} from '@storybook/addon-devkit'
API
Register manager side Addon panel
HOC to register addon UI and connect it to the addon store.
// in your addon `register.js`
import { register } from '@storybook/addon-devkit'
register(
{
...selectors,
},
({ global, local }) => ({
...globalActions,
...localActions,
})
)(AddonPanelUI);
where selectors
is an object with functions like:
{
deepData: store => store.path.to.deep.store.data,
}
and actions
could be "global" and "local". Global actions affects on the global part of store, while local only on the data related to the current story.
({ global, local }) => ({
// action to manipulate with common data
increase: global(store => ({
...store,
index: store.index + 1,
})),
// action to manipulate with current story data
// usage: setBackground('#ff66cc')
setBackground: local((store, color) => ({
...store,
backgroundColor: color,
})),
// action to override data
// usage: update({...newData})
update: global(),
})
AddonPanelUI - is your component which appears on addon panel when you select appropriate tab
Note: the HOC automatically track the
active
state of addon and shows it only when it's necessary
register HOC will pass the follow props to the AddonPanelUI
component:
<AddonPanelUI
{...actions} // generated actions
{...selectors} // selected pieces of store
api={api} // storybook API object
active={active} // you don't need to do anything with it
store={store} // entire store. prefer to use selectors
kind={kind} // current story kind
story={story} // current story
ADDON_ID={ADDON_ID}
PANEL_ID={PANEL_ID}
PANEL_Title={PANEL_Title} // Title on the addon panel
rect={rect} // dimensions of panel area
/>
As soon as you change the store via actions both the AddonPanelUI
and storyDecorator
will be re-rendered with the new data.
Same if the data will come from the story - it will be updated
After initialization HOC will wait for init data from story and only after it will render UI
Create stories side decorator
HOC to create decorator and connect it to the addon store.
// in your addon `decorator.js`
import { createDecorator } from '@storybook/addon-devkit'
export const withMyAddon = createDecorator({
...selectors,
},
({ global, local }) => ({
...globalActions,
...localActions,
})
)(DecoratorUI, { isGlobal });
so then you can use your decorator this way:
// stories.js
import React from 'react';
import { storiesOf, addDecorator, addParameters } from '@storybook/react';
import { withMyAddon, myAddonParams } from 'my-addon';
// add decorator globally
addDecorator(withMyAddon({ ...initData }))
addParameters(myAddonParams({ ...globalParams }))
storiesOf('My UI Kit', module)
// ...or add decorator locally
.addDecorator(withMyAddon({ ...initData }))
.add(
'Awesome',
() => <Button>Make Awesome</Button>,
myAddonParams({ ...localParams })
)
DecoratorUI
could look like this:
const DecoratorUI = ({ context, getStory, selectedData }) => (
<div>
<h1>Title: {selectedData}</h1>
{getStory(context)}
</div>
);
When isGlobal = true
decorator will consider all passing data as global
Note: addon parameters will be merged with init data and available both for decorator and panel selectors
Pass parameters to addon
Creates functions for passing parameters to your addon
See usage above
import { setParameters } from '@storybook/addon-devkit'
export const myAddonParams = setParameters()
Addon config
In order to create addon you need to specify some unique parameters like event name, addon title, parameters key and others. They should be same on manager and preview sides. If you don't specify them addon-devkit will use the default ones.
To specify your own use setConfig
:
import { setConfig } from '@storybook/addon-devkit';
setConfig({
addId: 'dev_adk',
panelTitle: 'ADK DEV'
});
You should run it before using register
, setParameters
and createDecorator
Note: don't forget to use setConfig both in on manager and preview sides with the same parameters
Addon panel UI components
Components to organize UI in a row when panel in bottom position and in column when it on the right side
import { Layout, Block, register } from '@storybook/addon-devkit';
import { styled } from '@storybook/theming';
import './config'
const LayoutBlock = styled(Layout)`
...styles
`
const AddonBlock = styled(Block)`
...styles
`
const AddonPanel = () => (
<LayoutBlock>
<AddonBlock size={200}>
{UI1}
</AddonBlock>
<AddonBlock>
{UI2}
</AddonBlock>
<AddonBlock>
{UI3}
</AddonBlock>
</LayoutBlock>
)
register()(AddonPanel)
<Layout>
has display: flex
with flex-direction: row
when bottom and flex-direction: column
in right side.
You can specify the size of <Block>
. In case of horizontal layout it will be the width, in case of vertical - height of element.
Otherwise it will have flex-grow: 1
