ecto_state_machine
A finite state machine pattern implementation for Ecto schemas in Elixir applications.
What is ecto_state_machine?
EctoStateMachine is an Elixir library that implements the finite state machine pattern for Ecto schemas. It allows developers to define states, events, and transitions directly in their Ecto models, providing helper functions for state validation and changeset generation. The library solves the problem of managing complex state transitions in database-backed applications by making them explicit and testable.
Elixir developers building applications with Ecto who need to model stateful entities like users, orders, or documents with clear transition rules and validation.
Developers choose EctoStateMachine because it integrates seamlessly with Ecto's changeset workflow, requires minimal configuration, and allows custom callback logic for side effects during transitions. It avoids external dependencies while providing a clean, declarative API for state management.
