 * @example
 * ```ts
 * const extractor: ExtractorType = {
 *   ...
 *   async extract(filename, code, onMessageExtracted, ctx) {
 *     return extractFromFileWithBabel(filename, code, onMessageExtracted, ctx, {

 *       plugins: [
 *         "decorators-legacy",
 *         "typescript",
 *         "jsx",
 *       ],
 *     })
