How do I prevent sensitive data leaks in subscriptions?

Use granular topics rather than broad ones, and always implement authorization checks within the subscription configuration to ensure users only access data they are permitted to see.

What is the difference between a config and a trigger in Absinthe?

The config block defines the topic a client subscribes to, while the trigger defines which mutation automatically triggers a publication to specific topics.

How do I authenticate Absinthe subscriptions?

Authentication is handled by verifying user tokens in the Phoenix Socket's connect function and passing the verified user into the Absinthe context.

Can I scope subscriptions to specific users?

Yes, by defining dynamic topics that include unique user IDs and validating the user's identity within the subscription's configuration block.
