How to use the just-scripts.resolveCwd function in just-scripts

function expandSourcePath(pattern) {
  if (!pattern) {
    return null;
  }

  // just returns the relative paths
  if (pattern.startsWith('.')) {
    return pattern;
  }

  // tries to resolve the packages, handling scoped packages
  const splitPattern = pattern.split('/');
  const packageName = pattern[0] == '@' ? `${splitPattern[0]}/${splitPattern[1]}` : splitPattern[0];

  try {
    const resolvedPackageJson = resolveCwd(`${packageName}/package.json`);

    if (!resolvedPackageJson) {
      // returns pattern if the packageName didn't contain a package.json (not really a package)
      return pattern;
    }

    return pattern.replace(packageName, path.dirname(resolvedPackageJson));
  } catch (e) {
    console.error(e);
  }
}
