Example project using gRPC and http transcoding

This project is an example using gRPC gateway, Envoy proxy to transcode gRPC API server into REST API server. Furthermore, I use denny framework which is not transcode gRPC API server into REST API server. Denny not only exposes gRPC and http api server in 1 port but also invoke the code you wrote in grpc functions, does not trigger grpc call when you call http.

Generate gRPC stub

Generating client and server code and reverse-proxy for your REST API:

make gen-protobuf

Start project

• Run all project

make dc-all

• Use grpc gateway

make dc-gateway

• Use envoy

make dc-envoy

• Use denny

make dc-denny

Example API Calls:

Install extension REST client on VS Code for easy send api call with *.http files in /client folder

• List entities

curl -X GET 'http://localhost:8080/entities'

• Create entity

curl -X POST 'http://localhost:8080/entities' -d '{"name":"Phuc qua dep trai","description":"Kha la banh","url":"phucdeptrai.com.vn"}'

• Read entity

curl -X GET "http://localhost:8080/entities/5d11e96b9dadaf6eef8599be"

• Update entity

curl -X PUT 'http://localhost:8080/entities' -d '{"id":"5dff0ab0ac327677d38754dd","name":"Phuc dep trai vai","description":"Qua la banh","url":"phuchotboy.com.vn"}'

• Delete entity

curl -X DELETE "http://localhost:8080/entities/5d11e8ee9dadaf6eef8599b9"
