Golang server behind envoy proxy that communicates with a react client (typescript) via grpc (demo)

Client

1. Create react app with typescript support

npx create-react-app client --typescript

2. create client/proto folder

yarn add google-protobuf grpc grpc-web

4. generate client proto libraries

protoc -I todo/ todo/todo.proto --js_out=import_style=commonjs:client/src/proto --grpc-web_out=import_style=typescript,mode=grpcwebtext:client/src/proto

5. add /* eslint-disable */ to generated *.js files to make tslint happy

Server

6. Generate go models

protoc -I todo/ todo/todo.proto --go_out=plugins=grpc:todo

Envoy proxy

7. build envoy docker image:

docker build -t abarbarov/go-envoy-boilerplate:v1 .

Run everything

8. run go server

go run server.go

9. run envoy proxy

docker run -d -p 9090:9090 abarbarov/go-envoy-boilerplate:v1

10. run client app

yarn start
