Type-safe, statically checked composition of HTTP servers

Getting Started | Documentation | FAQ | Examples

Hyper is an experimental middleware architecture for HTTP servers written in PureScript. Its main focus is correctness and type-safety, using type-level information to enforce correct composition and abstraction for web servers. The Hyper project is also a breeding ground for higher-level web server constructs, which tend to fall under the framework category.

To learn more about Hyper, check out the documentation and the Getting Started tutorial.
