json-rpc

Fully-featured JSON-RPC 2.0 library for Haskell programs.

This JSON-RPC library is fully-compatible with JSON-RPC 2.0 and 1.0. It provides an interface that combines a JSON-RPC client and server. It can set and keep track of request ids to parse responses. There is support for sending and receiving notifications. You may use any underlying transport. Basic TCP client and server provided.

A JSON-RPC application using this interface is considered to be peer-to-peer, as it can send and receive all types of JSON-RPC message independent of whether it originated the connection.
