LH Persistent Forms

• Type: Plugin
• Lifecycle Stage: Experimental

LH Persistent Forms remembers what visitors type into forms, in their own browser, so a closed tab, a lost connection or a repeat visit doesn’t mean typing it all again.

• Per page: a half-written comment is saved as you type and put back if you return to the page. It’s cleared once the form is submitted.
• Across the site: your name and email are filled in for you on any form on the site.

Everything stays in the visitor’s browser, in IndexedDB; nothing is sent to the server, and passwords are never stored. Which fields are remembered is set with two filters. There are no settings screens.

It replaces LH Localforage and carries each visitor’s saved values over automatically. It uses the small idb-keyval library, shared through LH idb-keyval where that’s installed and bundled otherwise.
