Parsley.js is a JavaScript form validation library that lets you validate forms entirely through HTML data attributes without writing JavaScript. It requires jQuery and provides a dozen-plus built-in validators with extensive customization options.
Use cases
- validate html forms without writing javascript
- frontend form validation with data attributes
- give users instant feedback before form submission
- add required field and email format checks to a form
- dynamically validate forms as fields are added or removed
- reduce server load by validating forms client-side
When to choose
- you use jQuery and want declarative, attribute-based form validation
- you need a mature, stable, well-tested validation library
- you want extensive built-in validators with UX-focused customization
When to avoid
- you are building a modern framework app (React, Vue) with its own form ecosystem
- your project does not use jQuery
- you need a library with active feature development
