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
