github.com/exaring/ulid-protobuf

Encode ulids as protobuf directly.

Usage

• import the proto file in your proto code

  mymessage.proto:

  syntax = "proto3";
  
  package mypackage;
  
  import "ulid.proto";
  
  option go_package = "example.org/mypackage";
  
  message MyMessage {
    ulid.ULID id = 1;
  }
  
  

• add this library to your code:

  $ go get github.com/exaring/ulid-protobuf@latest
  

• Then compile your proto files with protoc, e.g.:

  $ protoc --proto_path=$(go list -m -f '{{.Dir}}' github.com/exaring/ulid-protobuf) \
           --go_out=paths=source_relative:. \
           --proto_path=. ./mymessage.proto
  

  Note the trick with --proto_path: it allows protoc to find the ulid.proto file inside the go module's source.
