tinyrpc

A small, modular, transport and protocol neutral RPC library that, among other things, supports JSON-RPC and zmq.

Project description

Note

Tinyrpc is being revised.

The current version will enter maintenance mode. I will keep it alive until Python2 is discontinued. It can be installed from pip using its version number e.g. pip install tinyrpc==0.9.1.

The main line of development will start with version 1.0.0. It will not try to remain compatible with the 0.9.x version. It will support Python3 only.

Main goals for version 1.0.0 are:

good Python3 support.
restructure the code to eliminate unnecessary dependencies.
rework and extend the documentation with more examples.

Motivation

As of this writing (in Jan 2013) there are a few jsonrpc libraries already out there on PyPI, most of them handling one specific use case (e.g. json via WSGI, using Twisted, or TCP-sockets).

None of the libraries, however, made it easy to reuse the jsonrpc-parsing bits and substitute a different transport (i.e. going from json via TCP to an implementation using WebSockets or 0mq).

In the end, all these libraries have their own dispatching interfaces and a custom implementation of handling jsonrpc.

tinyrpc aims to do better by dividing the problem into cleanly interchangeable parts that allow easy addition of new transport methods, RPC protocols or dispatchers.

Documentation

You’ll quickly find that tinyrpc has more documentation and tests than core code, hence the name. See the documentation at <https://tinyrpc.readthedocs.org> for more details, especially the Structure-section to get a birds-eye view.

Installation

pip install tinyrpc

will install tinyrpc with its default dependencies.

Optional dependencies

Depending on the protocols and transports you want to use additional dependencies are required. You can instruct pip to install these dependencies by specifying extras to the basic install command.

pip install tinyrpc[httpclient, wsgi]

will install tinyrpc with dependencies for the httpclient and wsgi transports.

Available extras are:

Option	Needed to use objects of class
gevent	optional in RPCClient, required by RPCServerGreenlets
httpclient	HttpPostClientTransport, HttpWebSocketClientTransport
jsonext	optional in JSONRPCProtocol
websocket	WSServerTransport
wsgi	WsgiServerTransport
zmq	ZmqServerTransport, ZmqClientTransport
