form-saver is a web component that wraps HTML forms and automatically saves field values to localStorage, restoring them if the user returns before submitting. It supports text inputs, textareas, selects, checkboxes, and radio buttons. After a successful submission, saved data is cleared. Optional attributes allow retaining specific fields post-submit, giving users an opt-in checkbox to control retention, customizing the storage key, and placing the retention UI anywhere in the form layout. The component also exposes JavaScript methods for manual save/restore/clear control. It follows progressive enhancement principles — forms remain fully functional without JavaScript.
