This as a sample template to generate Go Micro-services. This models a mono-repo style where all micro-services are in a single repository and share a common interfaces folder which contains all the interfaces of all micro-services

The interfaces folder is kept out so that multiple microservice interfaces can be added in different directories here and between microservice only interfaces need to be shared.

There is a Go Client, a TypeScript Client here; as well as an Envoy SideCar and Docker files and configurations (Make) to create a Kubernetes deployment for the GRPC server and its Envoy Side Car and access via Go Client (Does not need Envoy Side car for that!) or a Web Client ( via Google GRPC-Web framework of translating to JS client code the GRPC to what browsers can understand )

Please read also https://medium.com/techlogs/micro-services-git-d840305e6220 and the manuals for GRPC, GRPC-Web etc

• • The README.md has details of how to generate the Typescript and JavaScript scripts as well as package them in WebPack so that they can be accessed from the HTML (main.js is generated from WebPack) https://github.com/alexcpn/go_grpc_2022/blob/main/microservice_1/ts_client/dist/index.html Makefile for the TypeScript generation part: https://github.com/alexcpn/go_grpc_2022/blob/main/microservice_1/ts_client/Makefile

In a (linux) machine which has Go installed > 1.17 and
cd to microservice_x directory and run make once to install the protoc compiler related plugins for Go

After that run make all for all builds and rebuilds

• cd to microservice_x directory
• cd to integration_test and run 'go test'

• cd microservice_x/generated directory
• run server ./run_server
• run client ./go_client

To run server in docker

• docker run --rm --name test -p 50051:50051 run_server:1.2

If you just have 'make' installed and don't have any other dependency even Go you can build the same output in a Docker container First

• cd to microservice_x
• run 'make docker_image'
