transitions
A Ruby state machine implementation extracted from ActiveModel, providing event-driven state transitions with callbacks.
What is transitions?
Transitions is a Ruby state machine library that provides a declarative way to define states, events, and transitions for Ruby objects, particularly in Rails applications. It solves the problem of managing complex state logic by offering a clean DSL with callback hooks, guard conditions, and automatic scope generation.
Ruby and Rails developers who need to model stateful behavior in their applications, such as order workflows, user lifecycle management, or any domain requiring finite state machines.
Developers choose Transitions for its simplicity, seamless integration with ActiveModel and ActiveRecord, and robust feature set including callbacks, guards, and timestamps, all while avoiding the bloat of more complex state machine libraries.
