• hidden Allow transfer of hidden files. defaults to false
• index Default file name, defaults to 'index.html'
• defer If true, serves after return next(), allowing any downstream middleware to respond first.
• gzip Try to serve the gzipped version of a file automatically when gzip is supported by a client and if the requested file with .gz extension exists. defaults to true.
• br Try to serve the brotli version of a file automatically when brotli is supported by a client and if the requested file with .br extension exists (note, that brotli is only accepted over https). defaults to true.
• setHeaders Function to set custom headers on response.
• extensions Try to match extensions from passed array to search for file when no extension is sufficed in URL. First found is served. (defaults to false)
