| Name |
Description |
| DefaultValuesOfCorrectType |
Variable default values of correct type A GraphQL document is only valid if all variable default values are of the type expected by their definition. |
| FieldsOnCorrectType |
Fields on correct type A GraphQL document is only valid if all fields selected are defined by the parent type, or are an allowed meta field such as __typename |
| FragmentsOnCompositeTypes |
Fragments on composite type Fragments use a type condition to determine if they apply, since fragments can only be spread into a composite type (object, interface, or union), the type condition must also be a composite type. |
| KnownArgumentNames |
Known argument names A GraphQL field is only valid if all supplied arguments are defined by that field. |
| KnownDirectives |
Known directives A GraphQL document is only valid if all `@directives` are known by the schema and legally positioned. |
| KnownFragmentNames |
Known fragment names A GraphQL document is only valid if all ...Fragment fragment spreads refer to fragments defined in the same document. |
| KnownTypeNames |
Known type names A GraphQL document is only valid if referenced types (specifically variable definitions and fragment conditions) are defined by the type schema. |
| LoneAnonymousOperation |
Lone anonymous operation A GraphQL document is only valid if when it contains an anonymous operation (the query short-hand) that it contains only that one operation definition. |
| NoFragmentCycles |
No fragment cycles |
| NoUndefinedVariables |
No undefined variables A GraphQL operation is only valid if all variables encountered, both directly and via fragment spreads, are defined by that operation. |
| NoUnusedFragments |
No unused fragments A GraphQL document is only valid if all fragment definitions are spread within operations, or spread within other fragments spread within operations. |
| NoUnusedVariables |
No unused variables A GraphQL operation is only valid if all variables defined by that operation are used in that operation or a fragment transitively included by that operation. |
| PossibleFragmentSpreads |
Possible fragment spread A fragment spread is only valid if the type condition could ever possibly be true: if there is a non-empty intersection of the possible parent types, and possible types which pass the type condition. |
| ScalarLeafs |
Scalar leafs A GraphQL document is valid only if all leaf fields (fields without sub selections) are of scalar or enum types. |
| UniqueArgumentNames |
|
| UniqueFragmentNames |
Unique fragment names A GraphQL document is only valid if all defined fragments have unique names. |
| UniqueInputFieldNames |
Unique input field names A GraphQL input object value is only valid if all supplied fields are uniquely named. |
| UniqueOperationNames |
Unique operation names A GraphQL document is only valid if all defined operations have unique names. |
| VariablesAreInputTypes |
Variables are input types A GraphQL operation is only valid if all the variables it defines are of input types (scalar, enum, or input object). |
| VariablesInAllowedPosition |
Variables passed to field arguments conform to type |
