Mercury, a JSON-RPC library for Scala

A modular JSON-RPC 2.0 library that allows pluggable transport layers, JSON libraries, and effect/async monads. Developed at Lightform to communicate with embedded devices where the device is acting in the server role.

This project has the following guiding goals:

• Free and open source license
• Allow for swappable transports
• Allow for swappable JSON libraries
• Be practical when transport layer details leak (eg. user ID from HTTP auth request header needs to be available to logic code but isn’t in the params section of the request)
• Be usable without code generation (especially client), although we hope to eventually support code generation.
