A validation plugin for Backbone.js that validates models and form inputs with declarative rules.
Backbone.Validation is a plugin for Backbone.js that adds declarative validation to models and forms. It allows developers to define validation rules (e.g., required fields, email patterns, custom logic) directly on models, overriding Backbone's `validate` method. The plugin also provides hooks to display validation errors in views, improving user experience during form input.
Developers building Backbone.js applications who need robust client-side validation for models and forms, especially those looking to avoid repetitive validation code and integrate validation with user interfaces.
It offers a clean, extensible alternative to manual validation logic, with built-in validators, form binding, and server-side reuse. Developers choose it for its simplicity, convention-over-configuration approach, and seamless integration with Backbone's ecosystem.

Allows validation rules to be defined as hashes or functions on models, replacing ad-hoc conditional logic with a clean, convention-based approach, as shown in the examples with built-in validators like 'required' and 'pattern'.
Includes common validators such as email, length, range, and equality, plus extensible custom validators, reducing boilerplate code for typical validation scenarios.
Provides binding to Backbone views for real-time error display in forms, with hooks like 'valid' and 'invalid' callbacks, though the default implementation is basic and often requires overriding.
Supports use in Node.js to share validation logic between client and server, promoting consistency, as mentioned in the 'Using server validation' section.
Tightly coupled to Backbone.js and requires specific versions (Backbone >=1.0.0), making it unsuitable for projects not using this framework and limiting adoption in modern stacks.
The default error display implementation is described as 'a bit naïve' in the README, often necessitating custom overrides for production use, which adds development overhead.
Nested validation support was removed in v0.6.0 due to complexity and later reintroduced, indicating potential instability in advanced use cases, as noted in the release notes.
