• First, you'll need to install the required dependencies:

git clonecd simple-grpc-nodejsnpm i

• Then, let's create a gRPC service definition in example.proto:
• Next, let's create a server that implements the Greeter service:

First bash or terminal

node ./greeter.js

Second bash or terminal

node ./SayHello.js
