Appevents plugin for protobuf

v0.1.5 2023-02-06 08:38 UTC

Requires

• google/protobuf: ^3.21

MIT

• Leo Sjoberg

README

This protoc plugin is meant to be used together with https://github.com/jobilla/go-app-events.

It enables the use of a jobilla.appevents.event_name option on messages, which will generate a StringType method for your message's generated Go struct, making it compliant with the Message interface from the library.

This library only exists due to shortcomings in the design of the original library, and is primarily used internally at Jobilla. We will likely deprecate and archive this tool during 2023 as we migrate over to CloudEvents.

Installation

We recommend using Buf to generate your protobuf code. To use the tool, you will need the jobilla/appevents/options.proto from this library. This is published on Buf, and you can import it from your buf.yaml:

version: v1
deps:
  - buf.build/jobilla/appevents

If you're not using buf, you'll have to copy the proto file to your codebase.

You'll also need the protoc-gen-go-appevents binary. This is published with every release on this repository, and also in the jobilla/protoc-gen-go-appevents Docker image. We encourage building your own Buf image and importing the binary:

FROM bufbuild/buf

COPY --from=jobilla/protoc-gen-go-appevents /protoc-gen-go-appevents /usr/local/bin/protoc-gen-go-appevents

Usage

You can declare the compatibility name of your message using the jobilla.appevents.event_name option:

syntax="proto3";

import "jobilla/appevents/options.proto";

message User {
  option (jobilla.appevents.event_name) = "user";

  string email = 1;
  string name = 2;
}
