grpc.setDefaultTransport(NativeGRPCTransport({ withCredentials: true }));

Running a docker Server for example app

There is an envoy proxy in front of go server.

cd server
docker-compose up --build server envoy

Running a gRPC Server manually

You can also run the grpc server manually using the following instructions.

Install protoc

• protoc : link

Install for go

go get -u google.golang.org/grpc
go get -u github.com/golang/protobuf/proto
go install github.com/golang/protobuf/protoc-gen-go@latest
export PATH=$HOME/go/bin:$PATH

Install grpc-web

GROC_WEB_PLUGIN=protoc-gen-grpc-web-1.0.6-darwin-x86_64
curl -OL https://github.com/grpc/grpc-web/releases/download/1.0.6/$GROC_WEB_PLUGIN
sudo mv $GROC_WEB_PLUGIN /usr/local/bin/protoc-gen-grpc-web
chmod +x /usr/local/bin/protoc-gen-grpc-web

Generate stubs for js and go
