Sanitize front-end entry form field If I'm enabling a user to post to Craft using the front-end entry form, is there a way that I can sanitize the title of a post?

I'm looking to apply AP formatting to titles.

I know Stephen has a plugin Entitle that does this but I'd rather have it on the initial submission.

This is a JS app so I can't do it on the Twig side.
I would definitely not rely on client-side validation. It's fine to do it from a UX point of view, but you should also be doing it server-side as well.

If this is a Vue app, write a custom validator for Vee Validate
