Gravity Forms is an excellent plugin for creating forms, but requires loading jQuery in the front-end for AJAX submissions to work. Obiously we would like to avoid a full reload on submission, but also not include JQuery in this day and age where vanilla JavaScript is so capable. This plugin makes use of the built-in REST API in Gravity Forms, and uses that to submit the form and perform validation. File uploads and multi-page forms are supported. By only using vanilla JavaScript, this plugin is 1.5kB (v1.1 minified and gzipped), compared to the 31kB of jQuery (3.6.1 minified and gzipped). A 95% reduction in size!
