The example of gRPC project with Angular and Go.

Platform	Image size	Image version
Client
Server

• Angular 8.0.0
• Go 1.12
• Protocol Buffers 3.7.1

Use Docker Compose to build client, server and proxy together.

docker-compose build

Run client, server and proxy together.

docker-compose up

Client site with Angular:

http://localhost:80/

Server site with Go:

http://localhost:50051/

Access the Envoy Proxy at:

http://localhost:8080/

If you need to modify .proto files, you can go to ./proto and then you will need to compile them again.

cd proto
vim calc.proto

# After modify
cd ..
sh ./protoc.sh

The Docker Image will build client with production mode. If you need to use development mode.

cd ./client
npm start

And the client access path is

http://localhost:4200/

If you want to try your server endpoint without client and proxy.

cd ./server/test
go run main.go
