gRPCRest - (Still In Making)

This sample project is basically to showcase proper examples on gRPC , Rest endpoint and communication between them. Ideally in production scenario you may not see communication a rest on top of gRPC server. That's the reason in this project, there is a separate client to test out the gRPC server implementation. But intend here to demo multiple possibilities and it's possible implementation.

How to set up this project ?

#### Using in your windows/mac/ubuntu env :

- git clone <repo_git_url>
- cd /gRPCRest/src/
- Go to the specific folder
- python3 <gRPC_server_script_name> / It would run on 50051 port
- python3 <rest_server_script_name> / It would run on 50051 port

Using docker env :

- git clone <repo_git_url>
- cd /dsalgo/
- docker build -t sughosneo/dsalgo .
- docker run -it sughosneo/dsalgo /bin/bash

Details about repo / code base :

Writing Rest - JSON based API :

- Define app.py which would hold the server.
- Define the request.

Defining CustomerInfoSvc gRPC Server. Below are the steps :

- Define a service in a .proto file.
- Generate server and client code using the protocol buffer compiler.
- Use the Python gRPC API to write a simple client and server for your service.

- Below steps to help to generate required python class files from proto data structures.

$ pip install grpcio
$ pip install grpcio-tools

$ cd /projects/gRPCRest/src/api/gRPC/protos/
$ python -m grpc_tools.protoc  -I.  --python_out=.. --grpc_python_out=. CustomerInfoSvc.proto
$ python -m grpc_tools.protoc  -I.  --python_out=.. --grpc_python_out=. Customer.proto

- After running the above commands it would create respective python packages under gRPC folder.
- These generated python class files would be required to reference in gRPC communication between client and server.

Test Client(s) :

- For the rest API this project has a separate client - "CustomerInfoSvcRestClient" 
- And for the gRPC server there is a separate "CustomerInfoSvcgRPCClient"
