## What it is
The jQuery Validation Plugin provides drop-in client-side form validation for existing HTML forms, with extensive support for custom rules and methods. It is a widely used jQuery plugin distributed via npm and CDN.

## Use cases
- validate html forms client-side
- add inline validation messages to a form
- require fields in a jquery form
- custom email validation rules
- validate forms built with jquery

## When to choose
- you already use jQuery and need quick form validation
- you want drop-in validation with customizable rules

## When to avoid
- you are building a modern framework app (React/Vue) with its own form libraries
- you need server-side validation only

## Facets
- artifact type: plugin
- maturity: stable
- function: form-handling
- domain: web-development, frontend
- platform: browser
