Save GRPC Tools Output to a Specified Location

I want to generate the libraries for my GRPC Services as defined in my protobuf files.

I have a directory called libs at the root of my working directory.

How can I specify in the command below that my output be stored in the libs folder:

grpc_tools_node_protoc --js_out=import_style=commonjs,binary:.  --grpc_out=grpc_js: protos/location.proto

Thank you
