Allow registering multiple services in server application #40
Description
Currently, connect-python generated server constructor creates a new ConnectWSGI instance in each service function:
def wsgi_eliza_service(implementation: ElizaServiceProtocol) -> WSGIApplication:
app = ConnectWSGI()
app.register_unary_rpc("/connectrpc.eliza.v1.ElizaService/Say", implementation.say, eliza_pb2.SayRequest)
...
return appHowever, this makes hard to register multiple ConnectRPC services on a single WSGI application - scenarios like serving multiple services in a single instance or implementing health checking protocol.
I think it would be nice for the service constructor to take a ConnectWSGI instance as an argument to allow registering more than one service like below:
def wsgi_eliza_service(implementation: ElizaServiceProtocol, app = ConnectWSGI()) -> WSGIApplication:
app.register_unary_rpc("/connectrpc.eliza.v1.ElizaService/Say", implementation.say, eliza_pb2.SayRequest)
...
return app
