go-grpc-poc

This project aims to explore the gRPC world, focused in communication with servers through one API gateway, code generation from .protoc files and code enrichment from protobuf annotations

Dependencies

In order to generate the gRPC, protobuf and gRPC-gateway code with protoc, these projects are necessary:

• https://github.com/googleapis/googleapis
• https://github.com/grpc-ecosystem/grpc-gateway @ v1.16.0 & v2.6.0

And can be achieved through golang dependency management tool by running make bootstrap. Then, code can be generated by make protoc-generate.

To generate code with buf (https://github.com/bufbuild/buf) it's only necessary to call make buf-generate, and the tool will manage the deps for you.

Gateway & gRPC server implementations
