## Notes

Shelf is a Dart package for building web servers from handler functions. A handler takes a request and returns a response, and the package's example composes a pipeline of middleware around a handler before passing it to `shelf_io.serve`, which listens on a host and port. The package is published on pub.dev as `shelf` and developed in the dart-lang/shelf repository alongside the packages that build on it, which the README names as examples of extensions.
