Haptics don't trigger on useEffect or try/catch block

[pulgueta]

I'm using the react bindings for my application. When I complete an action and show a success toast which triggers inside a useEffect, I wanted to trigger the success haptic preset but it doesn't, same as when trying to trigger inside a try/catch block.

The haptics as of now have been triggered only with regular onClick handlers. Would be nice to have them trigger this way too.

Will try to make a contribution myself but I leave it here in case is already being developed!

Hi @pulgueta!

I also stumbled upon a similar requirement and tried doing some reading.

As per my understanding (with Claude), haptics on web rely on a transient user activation. This is a ~5 second window the browser sets when the user physically taps/clicks. That's why onClick handlers work (you're synchronously inside the user gesture) but useEffect, try/catch after await, or any callback that runs outside that window doesn't.

And simulating this user activation doesn't seem to be allowed :(

I would still love to have this though if there is some other possibility!
