The Active RPC

ActiveRpc

ActiveRecord associations for gRPC services.

Quick start

class Employee < ApplicationRecord
  include ActiveRpc::ModelExtensions

  active_rpc :core, :User, foreign_key: :user_id do
    attribute :name, :string
    attribute :email, :string
    attribute :department, :string
  end
end

# Bulk load user data in one gRPC call
Employee.all.with_user_data

# Filter employees by remote user attribute
Employee.where_rpc(:user_ids, department: 'Engineering')

Features

• rpc_belongs_to — Treat remote gRPC resources like local associations
• Bulk loading — with_user_data fetches all related records in one gRPC call
• Cross-service filtering — where_rpc filters local records by remote attributes
• Dirty tracking — Change remote attributes locally, propagate on save
• Bidirectional create/update — Creating/updating local records creates/updates remote resources

Installation

Add to your Gemfile:

gem 'the-active-rpc'

Configuration

ActiveRpc.configure do |config|
  config.service_resolver = ->(subsystem, service_name) {
    "::MyApp::#{subsystem.camelize}::#{service_name}".constantize
  }
end
