The Python micro framework for building gPRC application based on official `gRPC <https://github.com/grpc/grpc>`_ project.


* Free software: MIT license
* Documentation: https://grpcalchemy.readthedocs.io.

Installation
----------------

.. code-block:: shell

    $ pipenv install grpcalchemy
    ✨🍰✨

Only **Python 3.6+** is supported.

Example
--------

Server
========

.. code-block:: python

    from grpcalchemy.orm import Message, StringField
    from grpcalchemy import Server, Context, grpcmethod

    class HelloMessage(Message):
        text: str

    class HelloService(Server):
        @grpcmethod
        def Hello(self, request: HelloMessage, context: Context) -> HelloMessage:
            return HelloMessage(text=f'Hello {request.text}')

    if __name__ == '__main__':
        HelloService.run()


Then Using gRPC channel to connect the server:

.. code-block:: python

    from grpc import insecure_channel

    from protos.helloservice_pb2_grpc import HelloServiceStub
    from protos.hellomessage_pb2 import HelloMessage

    with insecure_channel("localhost:50051") as channel:
        response = HelloServiceStub(channel).Hello(
            HelloMessage(text="world")
        )
