FastGRPC

Fast to Code gRPC in Python 3.9+

Installation

Require Python 3.9+

pip install python-fast-grpc

Quick start

Create a simple gRPC service:

from pydantic import BaseModel
from fast_grpc import FastGRPC

app = FastGRPC(service_name="Greeter", proto="greeter.proto")

class HelloRequest(BaseModel):
    name: str

class HelloReply(BaseModel):
    message: str

@app.unary_unary()
async def say_hello(request: HelloRequest) -> HelloReply:
    return HelloReply(message=f"Greeter SayHello {request.name}")

if __name__ == '__main__':
    # Auto-generates .proto file and starts gRPC server
    app.run()

Test with a client:

import grpc
import greeter_pb2 as pb2
import greeter_pb2_grpc as pb2_grpc

channel = grpc.insecure_channel("127.0.0.1:50051")
stub = pb2_grpc.GreeterStub(channel)
response = stub.SayHello(pb2.HelloRequest(name="FastGRPC"))
print("Greeter client received: ", response)
