ghcjs-websockets aims to provide a clean, idiomatic,
efficient, low-level, out-of-your-way, bare bones,
concurrency-aware interface with minimal abstractions
inspired by common Haskell idioms found in libraries like
http://hackage.haskell.org/package/io-streams and the
The interface asbtracts websockets as simple IO/file
handles, with additional access to the natively "typed"
There are also convenience functions to directly decode
serialized data (serialized with
http://hackage.haskell.org/package/binary) sent through
The library is mostly intended to be a low-level FFI library, with the hopes that other, more advanced libraries maybe build on the low-level FFI bindings in order to provide more advanced and powerful abstractions. Most design decisions were made with the intent of keeping things as simple as possible in order for future libraries to abstract over it.
Most of the necessary functionality is in hopefully in
it for library construction.
