27 best Java Form Validation libraries in 2024

Data validation is a necessary step that allows for saving time and effort of a user when filling out forms on the web. Verify the field in two ways. 

By using built-in HTML elements (which have limited custom validation capabilities) or by using JavaScript validation libraries. JavaScript libraries provide pre-coded packages, which support legacy browsers that do not have a built-in validation framework. One major advantage of using JavaScript libraries is that it takes the extra load of data verification and error return off from the server-side. This enhances user experience and smoothens out the form-filling process. 

Listed below are some of the most popular form validation libraries based on JavaScript. The JSON-schema-validator is a code package that focuses on form field correctness and efficiency. AwesomeValidation is another JavaScript-based form validation library developed for use in Android, shrinking down validation to three steps only. Epubcheck is a code-package developed specifically for validation in e-book format files. Use these libraries to develop a flawless form on a web application.
