Individual file

It is possible to serve static files with a custom path pattern and NamedFile. To match a path tail, we can use a [.*] regex.


To serve files from specific directories and sub-directories, Files can be used. Files must be registered with an App::service() method, otherwise it will be unable to serve sub-paths.

By default files listing for sub-directories is disabled. Attempt to load directory listing will return 404 Not Found response. To enable files listing, use Files::show_files_listing() method.

Instead of showing files listing for directory, it is possible to redirect to a specific index file. Use the Files::index_file() method to configure this redirect.


NamedFiles can specify various options for serving files:

  • set_content_disposition - function to be used for mapping file's mime to corresponding Content-Disposition type
  • use_etag - specifies whether ETag shall be calculated and included in headers.
  • use_last_modified - specifies whether file modified timestamp should be used and added to Last-Modified header.

All of the above methods are optional and provided with the best defaults, But it is possible to customize any of them.

The Configuration can also be applied to directory service:
