Are you planning on supporting angular?

Just out of curiosity since convex seems it would go along rxjs very well I'm kind of surprised that angular support is not there. Are there any technical reasons for that or is it just a matter of preference?

optimistic delete rollback

I'm prototyping a feature where I can add and remove users to / from a group (called channel). Removal has constraints, removing the last ADMIN is disallowed. When trying to remove the last admin the mutation throws a Convex Error and the frontend displays a toast informing the user. When removing optimistically, the constraint is not enforced and the user is removed from the localstore. I'd expect that when the mutations throws, the optimistic update is rolled back but apparently this doesn't happen. Is there a way to debug this? Can I somehow inspec the local store to see if this is a UI problem? Attached: video on the left is without optimistic update, right with optimistic update

runafter vs wrapper-action

Hi there, I'm wondering what is the suggested approach for the following scenario: an API endpoint that needs to perform a mutation, (optionally retrieve some data,) and the perform an operation over the network, like an httpcall. At the moment I have two different cases in which I'm adopting two different strategies: - I'm sending emails after storing an invitation record in convex using scheduler.runAfer(0, internal.emails.sendemail) from whitin the mutation that stores the invitation record - I'm sending push notification after storing a message in convex. I have a convex action that wraps (1) the mutation that stores the message; (2) the query to retrieve the push subscriptions; (3) the action to send the notifications. What would be the suggested approach for this kind of scenarios?

resend not working in internalMutation

I had a problem where I wasn't able to send emails with Resend. My API key was configured, my resend domain was verified and magic link email were working fine (after setting the from param). But when I tried to send emails at runtime resend.emails.send() would give the error

{
  name: 'application_error',
  message: 'Unable to fetch data. The request could not be resolved.'
}

{
  name: 'application_error',
  message: 'Unable to fetch data. The request could not be resolved.'
}

After a long time debugging I found out that my problem was that I was trying to send emails from an internalMutation. I switched to internalAction and all immediately worked. Could someone please explain the reason for this?
I also read the docs extensively but I hadn't found or anticipated that this would happen
