Idea

Trying to write an application based on protobuff communication. The main idea is there will be micro-service and client written in

• python service
• golang

A common protobuff data structure will be shared among them. They will use that proto libs to comminucate between them using http protocol.

Folder structure

/protos
├──/libs
│   ├──/go
│   ├──/python
├──/python-service
└──/go-client 

go-client is holding go implementation for protobuf request and response parsing

python-service is serving and parsing data using protobuf over http.

protos is holding original .proto file and generate libs.

Commands

proto lib generate

To run library file run from root directory following command

python lib

protoc --go_out=protos/libs/go protos/users.proto

go lib

protoc --go_out=protos/libs/go protos/users.proto

python project run

• go to python project directory cd python-service
• setup virtual environment virtualenv venv (first time only)
• source it source venv/bin/activate
• install requirements pip install -r requirements.txt (first time only)
• to run the basic flask app run export FLASK_APP=main.py && python -m flask run

Boom! Server is running in http://127.0.0.1:5000/ :)

golang project run

• go to go project directory cd go-client
• run go run *.go

Yeahhh! Client is now calling http://127.0.0.1:5000/ to posting proto file, reading proto :)
