protected onBundleWarning(warning: rollup.RollupWarning): void {
    if (warning.code === "CIRCULAR_DEPENDENCY" || warning.code === "MISSING_NODE_BUILTINS") {
      return; // suppress superfluous warnings
    }
    const output = Unicode.stringOutput(OutputSettings.styled());
    if (warning.importer) {
      output.write(warning.importer);
      output.write(" ");
    }
    OutputStyle.blue(output);
    output.write("warning:");
    OutputStyle.reset(output);
    if (warning.message) {
      output.write(" ");
      output.write(warning.message);
    }
    console.log(output.bind());
