Custom format helpers

We provide some helper methods we use internally in some of the built-in formats to make building custom formats a bit easier.

They are accessible at style-dictionary/utils entrypoint, you can read more about them in the Utils -> Format Helpers docs.

import StyleDictionary from 'style-dictionary';
import { fileHeader, formattedVariables } from 'style-dictionary/utils';
name: 'myCustomFormat',
format: async ({ dictionary, file, options }) => {
const { outputReferences } = options;
const header = await fileHeader({ file });
return (
header +
':root {\n' +
formattedVariables({ format: 'css', dictionary, outputReferences }) +
