There's an excellent module for serializing and deserializing forms: https://www.npmjs.com/package/dom-form-serializer

However this is quite old and we have since gained FormData as a way to serialize forms into a string, which dom-form-serializer doesn't support (it has its own object format)

What's missing is a way to apply the contents of FormData back to a form (rehydrate, if you will).

This form.elements.namedItem() API can help match the field name in FormData to the actual fields, but then the logic to select the right checkbox, radio, select, multi-select isn't straightforward. It'd be great to have a modern, simple way to do this.
