Styledictionary/4/Hook Api Formats

Last update

Aug 31, 2024

What Changed

This codemod updates registered formats to be placed inside the hooks.formats property, instead of format, with a shift from the singular to the plural form. Additionally, the formatter handler function has been renamed to format for consistency. Some importable type interfaces have also been renamed.

Before

import StyleDictionary from 'style-dictionary';
import type { Formatter, FormatterArguments } from 'style-dictionary/types';

// register it with register method
StyleDictionary.registerFormat({
    name: 'custom/json',
    formatter: ({ dictionary }) => JSON.stringify(dictionary, null, 2),
});

export default {
    // OR define it inline
    format: {
        'custom/json': ({ dictionary }) => JSON.stringify(dictionary, null, 2),
    },
    platforms: {
        json: {
            files: [
                {
                    destination: 'output.json',
                    format: 'custom/json',
                },
            ],
        },
    },
};

After

import StyleDictionary from 'style-dictionary';
import type { FormatFn, FormatFnArguments } from 'style-dictionary/types';

// register it with register method
StyleDictionary.registerFormat({
    name: 'custom/json',
    format: ({ dictionary }) => JSON.stringify(dictionary, null, 2),
});

export default {
    platforms: {
        json: {
            files: [
                {
                    destination: 'output.json',
                    format: 'custom/json',
                },
            ],
        },
    },

    hooks: {
        formats: {
            'custom/json': ({ dictionary }) =>
                JSON.stringify(dictionary, null, 2),
        },
    },
};
