Fast to Code gRPC in Python 3.7+
Require Python 3.7+
pip install python-fast-grpc- Run a gRPC application
from fast_grpc import BaseSchema, FastGRPC, ServicerContext, method
app = FastGRPC()
class HelloRequest(BaseSchema):
name: str
class HelloReply(BaseSchema):
message: str
class Greeter:

async def say_hello(self, request: HelloRequest, context: ServicerContext) -> HelloReply:
return HelloReply(message=f"Greeter SayHello {request.name}")
app.add_service(Greeter)
# this step will generate .proto file and python gRPC code, then start a grpc server
app.run()- Client invoke
