## What it is
A validation plugin for Backbone.js that lets you declare validation rules on models and validates both models and form input. It overrides Backbone's validate method and provides hooks for custom error message display.

## Use cases
- validate backbone models with declarative rules
- validate form input in a backbone app
- show validation error messages to users
- reuse model validation on node.js server
- replace nested if/else validation logic

## When to choose
- you maintain a legacy Backbone.js application needing structured model validation
- you want declarative validation rules instead of manual validate overrides

## When to avoid
- you are starting a new project with a modern frontend framework
- you need actively maintained validation tooling
- you do not use Backbone.js

## Facets
- artifact type: plugin
