Protocol Buffers

Additional rules related to Protocol Buffers and gRPC.

Support for compiling both for C++, Java, Python, Go and Javascript is built into Please, these are additional rules to add extra functionality.

gRPC Gateway

Rules extending the grpc_library rule to generate a grpc-gateway stub for a reverse proxy server.

The grpc_gateway_library rule replaces grpc_library; it works identically for all languages other than Go, which it produces the additional gateway code for. It also adds an additional language, swagger, which generates a Swagger description of the API. The usual way of getting at that is to use a grpc_swagger_library which depends on the grpc_gateway_library rule.

In addition to the usual proto dependencies, you will need to set the following variables in the [buildconfig] section of .plzconfig:

  • grpc-gateway-plugin: protoc plugin rule that is used for codegen. You can set this up with a go_get rule to get github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway.
  • grpc-gateway-dep: proto dependency for grpc-gateway protos. Typically is a grpc_gateway_api rule.
  • grpc-gateway-go-dep: runtime grpc-gateway library. Needed to compile the Go rules. You can again use a go_get rule, this time to fetch github.com/grpc-ecosystem/grpc-gateway/runtime.

There's an example of this in the test subdirectory.
