[![2dZHSs.md.png](https://i.ibb.co/WDZHJdp/chairstack.png)](https://i.ibb.co/WDZHJdp/chairstack.png)

This project contains implementation of REST and gRPC for a small application called ChairStack using Go Lang. 

##### To compile .proto to .go file

```

protoc services.proto --go_out=plugin=grpc .

```

##### To compile .proto to .js file

```

 protoc services.proto --js_out=import_style=commonjs:..\client\proto --grpc-web_out=import_style=commonjs,mode=grpcwebtext:..\client\proto

```

#### gRPC Web Wrapper

```

grpcServer := grpc.Server()

grpcWebServer := grpcweb.WrapServer(grpcServer)

httpServer = &http.Server{

  Handler: h2c.NewHandler(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { 

    if r.ProtoMajor == 2 {

      grpcWebServer.ServeHTTP(w, r)

    } else { 

      w.Header().Set("Access-Control-Allow-Origin", "*")

      w.Header().Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE")

      w.Header().Set("Access-Control-Allow-Headers", "Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization, X-User-Agent, X-Grpc-Web")

      w.Header().Set("grpc-status", "")

      w.Header().Set("grpc-message", "") 

      if grpcWebServer.IsGrpcWebRequest(r) {

        grpcWebServer.ServeHTTP(w, r) 

      }

    }

  }), &http2.Server{}),

}

```
