dexkitGlorious DX for Rails

Typed operations, domain events, form objects, and query builders – four base classes your Rails app needs to roll with advantage.

Dex::Operation

Service objects with typed props, structured errors, transactions, callbacks, async execution, advisory locks, and database recording.

Learn more

Dex::Event

Immutable domain events with pub/sub, async handlers via ActiveJob, retries with backoff, causality tracing, and optional persistence.

Learn more

Dex::Form

Form objects with ActiveModel attributes, normalization, validation, nested forms, and full Rails form builder compatibility.

Learn more

Dex::Query

Declarative filters and sorts for ActiveRecord and Mongoid – type coercion from params, scope injection, and Rails form binding.

Learn more

Testing built in

Minitest helpers for operations and events – execution, assertions, stubs, spies, contract verification, and a global activity log.

See testing docs

Registry & Export

Auto-tracked class registry, contract export as hashes or JSON Schema, description DSL for operations and events, and a rake task for bulk export.

See export docs

LLM Tools

Turn operations into LLM-callable tools via ruby-llm – typed params, guards as preconditions, explain for preflight checks, and recording as audit trail.

See LLM docs
