Argument values of correct type
Variable default values of correct type
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.
Fields on correct type
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 typenamme
Fragments on composite type
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.
Known argument names
Known argument names
A GraphQL field is only valid if all supplied arguments are defined by that field.
Known directives
Known directives
A GraphQL document is only valid if all @directives
are known by the
schema and legally positioned.
Known fragment names
Known fragment names
A GraphQL document is only valid if all ...Fragment
fragment spreads refer
to fragments defined in the same document.
Known type names
Known type names
A GraphQL document is only valid if referenced types (specifically variable definitions and fragment conditions) are defined by the type schema.
Lone anonymous operation
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.
No undefined variables
No undefined variables
A GraphQL operation is only valid if all variables encountered, both directly and via fragment spreads, are defined by that operation.
No unused fragments
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.
No unused variables
No unused variables
A GraphQL operation is only valid if all variables defined by an operation are used, either directly or within a spread fragment.
Overlapping fields can be merged
Overlapping fields can be merged
A selection set is only valid if all fields (including spreading any fragments) either correspond to distinct response names or can be merged without ambiguity.
Possible fragment spread
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.
Provided required arguments
Provided required arguments
A field or directive is only valid if all required (non-null) field arguments have been provided.
Scalar leafs
Scalar leafs
A GraphQL document is valid only if all leaf fields (fields without sub selections) are of scalar or enum types.
Unique argument names
Unique argument names
A GraphQL field or directive is only valid if all supplied arguments are uniquely named.
Unique fragment names
Unique fragment names
A GraphQL document is only valid if all defined fragments have unique names.
Unique input field names
Unique input field names
A GraphQL input object value is only valid if all supplied fields are uniquely named.
Unique operation names
Unique operation names
A GraphQL document is only valid if all defined operations have unique names.
Variables are input types
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).
Variables passed to field arguments conform to type
Argument values of correct type
A GraphQL document is only valid if all field argument literal values are of the type expected by their position.
