## About Shelf

Shelf makes it easy to create and compose web servers and parts of web servers. How?

- Expose a small set of simple types.
- Map server logic into a simple function: a single argument for the request, the response is the return value.
- Trivially mix and match synchronous and asynchronous processing.
- Flexibility to return a simple string or a byte stream with the same model.

It was inspired by [Connect](https://github.com/senchalabs/connect) for NodeJS
and [Rack](https://github.com/rack/rack) for Ruby.

See the [package:shelf readme](pkgs/shelf/) for more information.
