💡 Hint

Common Mistakes

Using 'Mutation' or 'Subscription' as the root query type.

Naming the type something unrelated like 'Visible'.

The root query type in GraphQL schema is named Query. This makes the schema visible for queries.

💡 Hint

Common Mistakes

Using '@deprecated' which only marks a field as deprecated but does not hide it.

Using '@skip' or '@include' which control query execution, not schema visibility.

The @hidden directive is used to hide fields from the schema visibility.

💡 Hint

Common Mistakes

Just renaming the type without hiding it.

Using '@deprecated' which does not hide the type.

To hide the Mutation type, you must add the @hidden directive after its name in the schema definition.

4fill in blank

hard

Fill both blanks to define a schema with a visible Query and a hidden Mutation.

GraphQL

schema { query: [1] mutation: [2] }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Not adding '@hidden' to Mutation.

Using 'Subscription' instead of 'Mutation' for mutation root.

The query root is set to Query to be visible, and the mutation root is set to Mutation @hidden to hide it.

GraphQL
