color: {
base: {
red: {
value: '#ff0000',
},
},
},
};

javascript/module-flat

Creates a CommonJS module with the whole style dictionary flattened to a single level.

Example:

vars.cjs
module.exports = {
ColorBaseRed: '#ff0000',
};

javascript/object

Creates a JS file a global var that is a plain javascript object of the style dictionary. Name the variable by adding a ‘name’ attribute on the file object in your config.

Example:

vars.js

module.exports = factory();
} else if (typeof exports === 'object') {
exports['_styleDictionary'] = factory();
} else if (typeof define === 'function' && define.amd) {
define([], factory);
} else {
root['_styleDictionary'] = factory();
}
})(this, function () {
return {
color: {
red: {
value: '#FF0000',
},
},
};
});

javascript/es6

Creates a ES6 module of the style dictionary.

config.json
{
"platforms": {
"js": {
"transformGroup": "js",
"files": [
{
"format": "javascript/es6",
"destination": "colors.js",
"filter": {
"type": "color"
}
}
]
}
}
}

Example:

vars.js
export const ColorBackgroundBase = '#ffffff';
export const ColorBackgroundAlt = '#fcfcfcfc';

typescript/es6-declarations

Creates TypeScript declarations for ES6 modules

config.json
{
"platforms": {
"ts": {
"transformGroup": "js",
"files": [
{
"format": "javascript/es6",
"destination": "colors.js"
},
{
"format": "typescript/es6-declarations",
"destination": "colors.d.ts"
}
]
}
}
}
ParamTypeDescription
optionsObject
options.outputStringLiteralsbooleanWhether or not to output literal types for string values. Defaults to false.

Example:

vars.ts
export const ColorBackgroundBase: string;
export const ColorBackgroundAlt: string;

typescript/module-declarations

Creates TypeScript declarations for module

config.json
{
"platforms": {
"ts": {
"transformGroup": "js",
"files": [
{
"format": "javascript/module",
"destination": "colors.js"
},
{
"format": "typescript/module-declarations",
"destination": "colors.d.ts"
}
]
}
}
}

Example:

vars.ts
export default tokens;
declare interface DesignToken {
value?: any;
type?: string;
name?: string;
comment?: string;
themeable?: boolean;
attributes?: Record<string, unknown>;
[key: string]: any;
}
declare const tokens: {
color: {
red: DesignToken;
};
};

As you can see above example output this does not generate 100% accurate d.ts. This is a compromise between of what style-dictionary can do to help and not bloating the library with rarely used dependencies.

Thankfully you can extend style-dictionary very easily:

build-tokens.js
import JsonToTS from 'json-to-ts';
StyleDictionaryPackage.registerFormat({
name: 'typescript/accurate-module-declarations',
formatter: function ({ dictionary }) {
return (
'declare const root: RootObject\n' +
'export default root\n' +
JsonToTS(dictionary.tokens).join('\n')
);
},
});

android/resources

Creates a resource xml file. It is recommended to use a filter with this format as it is generally best practice in Android development to have resource files organized by type (color, dimension, string, etc.). However, a resource file with mixed resources will still work.

This format will try to use the proper resource type for each token based on the category (color => color, size => dimen, etc.). However if you want to force a particular resource type you can provide a ‘resourceType’ attribute on the file configuration. You can also provide a ‘resourceMap’ if you don’t use Style Dictionary’s built-in CTI structure.

ParamTypeDescription
optionsObject
options.showFileHeaderbooleanWhether or not to include a comment that has the build date. Defaults to true
options.outputReferencesboolean | OutputReferencesFunctionWhether or not to keep references (a -> b -> c) in the output. Defaults to false. Also allows passing a function to conditionally output references on a per token basis.

Example:

resources.xml
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<color name="color_base_red_5">#fffaf3f2</color>
<color name="color_base_red_30">#fff0cccc</color>
<dimen name="size_font_base">14sp</color>

android/colors

Creates a color resource xml file with all the colors in your style dictionary.

It is recommended to use the ‘android/resources’ format with a custom filter instead of this format:

config.js
format: 'android/resources',
filter: {
type: "color"
}

Example:

resources.xml
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<color name="color_base_red_5">#fffaf3f2</color>
<color name="color_base_red_30">#fff0cccc</color>
<color name="color_base_red_60">#ffe19d9c</color>

android/dimens

Creates a dimen resource xml file with all the sizes in your style dictionary.

It is recommended to use the ‘android/resources’ format with a custom filter instead of this format:

config.js
format: 'android/resources',
filter: {
type: "dimension"
}

Example:

dimens.xml
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<dimen name="size_padding_tiny">5.00dp</dimen>
<dimen name="size_padding_small">10.00dp</dimen>
<dimen name="size_padding_medium">15.00dp</dimen>

android/fontDimens

Creates a dimen resource xml file with all the font sizes in your style dictionary.

It is recommended to use the ‘android/resources’ format with a custom filter instead of this format:

config.js
format: 'android/resources',
filter: {
type: "dimension"
}

Example:

font-dimens.xml
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<dimen name="size_font_tiny">10.00sp</dimen>
<dimen name="size_font_small">13.00sp</dimen>
<dimen name="size_font_medium">15.00sp</dimen>

android/integers

Creates a resource xml file with all the integers in your style dictionary. It filters your design tokens by token.type === 'time'

It is recommended to use the ‘android/resources’ format with a custom filter instead of this format:

config.js
format: 'android/resources',
filter: {
type: 'time'
}

Example:

integers.xml
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<integer name="time_duration_short">1000</integer>
<integer name="time_duration_medium">2000</integer>
<integer name="time_duration_long">4000</integer>

android/strings

Creates a resource xml file with all the strings in your style dictionary. Filters your design tokens by token.type === 'content'

It is recommended to use the ‘android/resources’ format with a custom filter instead of this format:

config.js
format: 'android/resources',
filter: {
type: 'content'
}

Example:

icons.xml
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<string name="content_icon_email">&#xE001;</string>
<string name="content_icon_chevron_down">&#xE002;</string>
<string name="content_icon_chevron_up">&#xE003;</string>

import androidx.compose.ui.graphics.Color
object StyleDictionary {
val colorBaseRed5 = Color(0xFFFAF3F2)
