A lightweight, dependency-free JavaScript form validation library modeled on the CodeIgniter form validation API. It validates form fields against a dozen-plus rules with customizable messages and custom validation callbacks.
Use cases
- validate html form fields before submission
- add required and email validation to a form in vanilla javascript
- check password confirmation matches in a form
- customize validation error messages
- write custom validation rules with callbacks
When to choose
- you need a tiny (~2kb gzipped) dependency-free form validator
- you like the CodeIgniter validation rule syntax
- you must support very old browsers like IE6
When to avoid
- you want an actively maintained library with modern releases
- you need framework-integrated validation (React, Vue, Angular)
- you need async or schema-based validation
