ember-changeset
An Ember.js addon for managing and validating changes to objects with a Data Down, Actions Up (DDAU) approach.
What is ember-changeset?
ember-changeset is an Ember.js addon that provides a changeset abstraction for managing and validating changes to objects like Ember Data models, Ember Objects, or plain JavaScript objects. It ensures objects never enter an invalid state by only allowing valid changes to be set, making it ideal for form handling in Ember applications. The addon is designed to be unopinionated about validation libraries and integrates with existing solutions.
Ember.js developers building forms or handling user input in applications, particularly those following Data Down, Actions Up (DDAU) patterns and needing robust change management with validation. It is also suitable for teams using TypeScript or requiring strict type checking in templates.
Developers choose ember-changeset because it prevents invalid object states by validating changes before they are applied, unlike other libraries that validate after setting. It offers flexible validation integration, supports nested properties, and provides fine-grained control over changes with methods for execution, rollback, merging, and snapshots.
