Description

Tiny JSON-RPC 2.0 client. Functions for implementing the client side of JSON-RPC 2.0. See http://www.jsonrpc.org/specification.

If you have monad with MonadIO, MonadThrow and MonadReader instances, it can be used as base for JSON-RPC calls.

Example:

  newtype MyMonad a = ...

  instance JsonRpc MyMonad

  foo :: Mymonad Text
  foo = remote "foo"

Arguments of function are stored into params request array.

Example:

  myMethod :: JsonRpc m => Int -> Bool -> m String
  myMethod = remote "myMethod"
