dexkitTyped patterns for Rails, crafted for DX

Operations, events, forms, and queries – four base classes with contracts that enforce themselves. Equip to roll with advantage.

Dex::Operation

Encapsulate a business action with typed inputs and structured errors. Transactions, callbacks, async, and tracing are built into the pipeline.

Publish typed, immutable domain events and react with handler classes. Async dispatch, retries, causality tracing, and persistence are built in.

Declare filters and sorts for ActiveRecord and Mongoid scopes. Params coercion, scope composition, and Rails form binding included.

Define form objects with typed fields, validation, and nested forms. Works with Rails form builders and exports to JSON Schema.

Minitest helpers for operations and events — assertions, stubs, spies, and a global activity log for verifying what ran and why.

See testing docs

Every operation, event, form, and query is auto-tracked in a registry. Export contracts as hashes or JSON Schema with a single rake task.

See export docs

Declare preconditions as named guards and check "can this run?" from views and controllers. Explain runs a full preflight check with no side effects.
