    // defaults
    data = data || {};
    var cancel = false;
    const resConfig = Object.assign(data, {
      platformRef,
      cancelHandler: () => cancel,
      time: _options.time,
      asyncDestroy: _options.asyncDestroy,
      id: _options.id()
    });

    var req: any = (data.req && data.req.on && data.req) ||
    (data.request && data.request.on && data.request);

    req.on('close', () => cancel = true);


    function readContent(content) {
      const document: string = content.toString();
      resConfig.document = document;

      // convert to string

      return (_options.precompile ?
        platformRef.serializeModule(_options.main(resConfig), resConfig) :
        platformRef.serializeModuleFactory(_options.mainFactory(resConfig), resConfig)
      )
        .then(html => {
          done(null, html);
        })
        .catch(e => {
          console.error(e.stack);
          // if server fail then return client html
          done(null, document);
        });
    }

    // read file on disk
    try {
