Questions tagged [buf]

The Buf tool, here, allows the user to develop compiler configurations that can be used to transform protobuf .proto files to source code in a predictable manner, without having to interact directly with protoc-gen-go, protoc-gen-grpc or other protobuf plugins. This tool also offers access to remote repositories for uploading and sharing protobuf code, known as the Buf Schema Registry or BRS. Additionally, buf offers integration with GitHub actions.
