realtime_check_permission( )

Checks permissions for a subscriber on a channel or channel resource.

The realtime_check_permission hook is triggered when a site visitor subscribes to a channel to check what permissions the subscriber will have.

The realtime_check_permission() function is not a function that you call from your code. You define the function in a file named realtime-permissions.js in your site's Backend section.

Important:

• If this function isn't defined, all subscribers will receive the default permissions: {"read": true}.
• In Wix Studio, you don't need to define this function, but you must create a backend file named realtime-permissions.js. Without this file, subscriptions will fail.

Implement permissions logic for channels and subscribers by either:

• Including all permissions logic in the body of this function.
• Use the PermissionsRouter to add permissions logic per channel. Then call check() in the body of this function and return the permissions object it returns.
