Alicorn

Alicorn is a Python grpc framework with built in dependency injection and middleware management.

NB: This project is in alpha status at the moment, some functionality may be missing.

from alicorn import Alicorn, GrpcContext, Depends
from helloworld_pb2 import HelloWorldRequest, HelloWorldResponse
from helloworld_pb2_grpc import HelloWorldServicer


app = Alicorn()
app.debug = True


class Database:
    pass    


@app.service
class HelloWorld(HelloWorldServicer):

    def SayHello(self, request: HelloWorldRequest, context: GrpcContext, *, database: Database = Depends()):
        return HelloWorldResponse(message=f"Hello {request.name}")


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