This is a example showing how you can create a service using gRPC.

This code was written as a example only and does not follow any good practice rules, since it wasn't on the scope of this presentation.

• Python 3.9.X (This should work as-is in python 3.10.X)
• Node v17.3.0

To start the gRPC server just execute the following command:

1. $ python -m venv venv
2. $ pip install -r requirements.txt
3. $ python -m server.main

This will start an insecure gRPC server on https://0.0.0.0:50051

ps.: This server uses an insecure channel for communications, although this is not a problem for learning purposes this SHOULD NOT be used as-is in production.

ps².: The creation of a secure channel communication is beyond the scope of this example.

To start the node.js client execute the following commands:

1. $ cd client_node
2. $ yarn (or $ npm install)
3. $ yarn start (or $ npm start)

This will start a client Express app on http://localhost:3000

To start the python client execute the following command:

1. $ uvicorn client_python.main:app --reload

This will start a client FastAPI app on http://localhost:8000
