Demo code that highlights gRPC based communication between client and server.
Assuming you are at the top of the project tree 'simple-grpc'
There are three directories
proto
client
server
the service is expressed as a 'proto' file leave.proto
run the server as node server or node server/index.js
there are two clients, implemented in 'node' and 'python 3.x' respectively.
run the 'node' client as
node client/node/ or `node client/node/index.js'
run the 'python' client as
cd client/python
./do_1_gen.sh
./do_2_run.sh
