truncate( )

Removes all items from a collection.

The truncate() function returns a Promise that resolves after all items have been removed from the specified collection.

truncate() runs when at least one of the following is true:

  • The current user is the site owner.
  • The request is performed in backend code with a suppressAuth options value of true.

Calling the truncate() function does not trigger any hooks.

Note: truncate() also clears multiple-item reference fields in collections referenced by the specified collection. For example, suppose you have a Movies collection with an Actors field that contains multiple references to items in a People collection. Truncating the Movies collection also clears the data in the corresponding multiple-item reference field in the People collection.
