          type: 'es6',
        },
      },
      // All non js/ts/jsx/tsx files will be copied to outdir by default. You can compile them or do any other operations before copying
      beforeCopy: async meta => {
        if (meta.suffix === '.scss') {
          const result = sass.compile(meta.filePath);

          await mkdir(meta.outDir, { recursive: true });
          await writeFile(meta.outPath.replace(/\.scss$/, '.css'), result.css);

          return true;  // prevent default copy operation
        }
