Description

A Storybook addon. It allows you to quickly find any color from your custom color palette and set it on component's controls and/or copy to clipboard.

Migrate from v1 to v2

To migrate from v1 to v2 adjust parameters in preview.js to match the pattern shown in Add palettes in usage section below.

Usage

$ npm i storybook-color-picker

Add to your Storybook

In your .storybook folder find main.js file and add this addon like below.

  module.exports = {
    ...
    "addons": [
      ...
      "storybook-color-picker"
    ]
  };

Add palettes

Globaly

This will add color picker and palettes everywhere in your storybook.

In your .storybook folder find preview.js file and add your color palette to parameters like below. Scroll down to find out how your color palette must look like.

import yourFirstColorPalette from './yourFirstColorPalette.json';
import yourSecondColorPalette from './yourSecondColorPalette.json';

export const parameters = {
  ...
  colorPalettes: {
    default: 'Your first palette name', // Name of default palette for all components and its stories. Optional (fallback to first palette from the palettes array).
    palettes: [
      {
        name: 'Your first palette name', // string
        palette: yourFirstColorPalette, // Palette as an Object or an Array. See bellow.
      },
      {
        name: 'Your second palette name',
        palette: yourSecondColorPalette,
      },
    ]
  }
};

On component

This will add color picker and palettes to all component's stories.

In MyComponent.stories.js add:

export default {
  ...
  parameters: {
    ...
    colorPalettes: {
      default: 'Your first palette name',
      palettes: [
        {
          name: 'Your first palette name',
          palette: yourFirstColorPalette,
        },
        {
          name: 'Your second palette name',
          palette: yourSecondColorPalette,
        },
      ]
    }
  }
};

On story

This will add color picker and palettes to specific story.

In MyComponent.stories.js add:

export const Primary = Template.bind({});

Primary.parameters = {
  ...
    colorPalettes: {
      palettes: [
        {
          name: 'Your first palette name',
          palette: yourFirstColorPalette,
        },
      ]
    }
}

Palette

as Object

type ColorPaletteAsObject = Record<string, Record<string, string> | string>;

Example:

  {
    "white": "#fff", // valid hex, rgb, rgba, hsl, hsla
    "black": "#000",
    "light": {
      " 500": "#aaa",
      " 100": "rgba(238, 238, 238, .8)",
      " 200": "rgb(238, 238, 238)",
      " 300": "hsla(0, 0%, 73%, .8)",
      " 400": "hsl(0, 0%, 73%)"
    },
    "dark": {
      "0100": "#888",
      "0500": "#000",
      "0400": "#222",
      "0200": "#666",
      "0300": "#444"
    }
  }

Usefull tip: add white spaces or zeros before numerical keys to prevent auto sorting

as Array

  type ColorPaletteAsArray = {
    label: string,
    values: [
      {
        label: string,
        value: string,
      }
    ],
  };

Example:

  [
    {
      "label": "light",
      "values": [
        {
          "label": "100",
          "value": "#fff"
        },
        {
          "label": "200",
          "value": "#aaa"
        }
      ]
    },
    {
      "label": "dark",
      "values": [
        {
          "label": "100",
          "value": "#222"
        },
        {
          "label": "200",
          "value": "#000000"
        }
      ]
    }
  ]

Set default palette on component or its stories

On component

This will apply for all component's stories.

In MyComponent.stories.js add:

export default {
  ...
  parameters: {
    defaultColorPalette: 'Your second palette name',
  }
};

On story

This will apply for specific story.

In MyComponent.stories.js add:

export const Primary = Template.bind({});

Primary.parameters = {
  defaultColorPalette: 'Your first palette name',
}

Default palette specificity:

The following list increases by specificity.

1. default set on parameters in preview.js
2. defaultColorPalette set on component parameters
3. defaultColorPalette set on story MyComponent.parameters

Apply selected color to component's control

All controls with type of "color" will be detected automatically. You can add extra controls to whitch color may be applied. Only controls of type "text" may be added as extra.

On component

Add list of extra controls to all component's stories.

In MyComponent.stories.js add:

export default {
  ...
  argTypes: {
    backgroundColor: { control: 'color' }, // Color controls will be detected automatically
    label: { control: 'text' }, // Text controls may be added as extra
    text: { control: 'text' }, // Text controls may be added as extra
  },
  parameters: {
    ...
    applyColorTo: ['label'] // Must match argType key
  }
};

On story

Add list of extra controls to selected story to overwrite list added to component globaly as in example above.

In MyComponent.stories.js add:

export const Primary = Template.bind({});

Primary.parameters = {
  ...
  applyColorTo: ['text'], // Pass empty array to clear extra controls
};
