How to run

1. go run grpc-http-gateway/main.go
2. go run grpc-server/main.go

Generate stubs using

protoc -I . \
    --go_out ./gen/go/ --go_opt paths=source_relative \
    --go-grpc_out ./gen/go/ --go-grpc_opt paths=source_relative \
    service/v1/your_service.proto

Generate reverse-proxy using

protoc -I . --grpc-gateway_out ./gen/go \
    --grpc-gateway_opt logtostderr=true \
    --grpc-gateway_opt paths=source_relative \
    --grpc-gateway_opt generate_unbound_methods=true \
    service/v1/your_service.proto


protoc -I . --grpc-gateway_out ./gen/go \
    --grpc-gateway_opt logtostderr=true \
    --grpc-gateway_opt paths=source_relative \
    service/v1/your_service.proto

Generate using buf

1. at proto directory, do buf mod update buf build
2. at root directory, do buf generate proto
