This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to v4, this PR will be updated.

⚠️⚠️⚠️⚠️⚠️⚠️

v4 is currently in pre mode so this branch has prereleases rather than normal releases. If you want to exit prereleases, run changeset pre exit on v4.

Major Changes

• 502dbd1: BREAKING: All of our hooks, parsers, preprocessors, transforms, formats, actions, fileHeaders and filters, support async functions as well now. This means that the formatHelpers -> fileHeader helper method is now asynchronous, to support async fileheader functions.

  import StyleDictionary from 'style-dictionary';
  
  const { fileHeader } = StyleDictionary.formatHelpers;
  
  StyleDictionary.registerFormat({
    name: 'custom/css',
    // this can be async now, usually it is if you use fileHeader format helper, since that now always returns a Promise
    formatter: async function ({ dictionary, file, options }) {
      const { outputReferences } = options;
      return (
        // this helper is now async! because the user-passed file.fileHeader might be an async function
        (await fileHeader({ file })) +
        ':root {\n' +
        formattedVariables({ format: 'css', dictionary, outputReferences }) +
        '\n}\n'
      );
    },
  });
