`JSON-RPC2.0 <http://www.jsonrpc.org/specification>`_ and `JSON-RPC1.0 <http://json-rpc.org/wiki/specification>`_ transport specification implementation.
|
||
|
|
Supports Python 2.6+, Python 3.3+, PyPy. Has optional Django and Flask support. 200+ tests.
|
||
|
|
|
||
|
|
Features
|
||
|
|
--------
|
||
|
|
|
||
|
|
This implementation does not have any transport functionality realization, only protocol.
|
||
|
|
Any client or server implementation is easy based on current code, but requires transport libraries, such as requests, gevent or zmq, see `examples <https://github.com/pavlov99/json-rpc/tree/master/examples>`_.
|
||
|
|
|
||
|
|
- Vanilla Python, no dependencies.
|
||
|
|
- 200+ tests for multiple edge cases.
|
||
|
|
- Optional backend support for Django, Flask.
|
||
|
|
- json-rpc 1.1 and 2.0 support.
|
||

Install
|
||
|
|
-------
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
pip install json-rpc
|
||
|
|
|
||
|
|
Tests

|
Quickstart
|
||
|
|
^^^^^^^^^^
|
||
|
|
This is an essential part of the library as there are a lot of edge cases in JSON-RPC standard. To manage a variety of supported python versions as well as optional backends json-rpc uses `tox`:
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
tox
|
||
|
|
|
||
|
|
.. TIP::
|
||
|
|
During local development use your python version with tox runner. For example, if your are using Python 3.6 run `tox -e py36`. It is easier to develop functionality for specific version first and then expands it to all of the supported versions.
|
||
|
|
|
||
|
|
Continuous integration
|
||
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
||
|
|
This project uses `CircleCI <https://circleci.com/>`_ for continuous integration. All of the python supported versions are managed via `tox.ini` and `.circleci/config.yml` files. Master branch test status is displayed on the badge in the beginning of this document.
|
||
|
|
|
||
|
|
Test matrix
|
||
|
|
^^^^^^^^^^^
|
||
|
|
json-rpc supports multiple python versions: 2.6+, 3.3+, pypy. This introduces difficulties with testing libraries and optional dependencies management. For example, python before version 3.3 does not support `mock` and there is a limited support for `unittest2`. Every dependency translates into *if-then* blocks in the source code and adds complexity to it. Hence, while cross-python support is a core feature of this library, cross-Django or cross-Flask support is limited. In general, json-rpc uses latest stable release which supports current python version. For example, python 2.6 is compatible with Django 1.6 and not compatible with any future versions.

There are `several libraries <http://en.wikipedia.org/wiki/JSON-RPC#Implementations>`_ implementing JSON-RPC protocol. List below represents python libraries, none of the supports python3. tinyrpc looks better than others.
