Directives

The Neo4j GraphQL Library provides the following directives to be used whilst defining types:

Directive Description

Directive	Description
`@alias`	Maps a GraphQL schema field to a Neo4j property on a node or relationship.
`@authentication`	Requires authentication checks when accessing the type.
`@authorization`	Specifies authorization rules for queries and mutations on the type.
`@coalesce`	Exposes a mechanism for querying against non-existent, `null` values on a node.
`@customResolver`	Specifies that a field is resolved by a custom resolver, and allows the specification of any required fields that is passed as arguments to the custom resolver.
`@cypher`	Overrides field resolution (including `Query` and `Mutation` fields), instead resolving with the specified Cypher.
`@default`	Allows for the setting of a default value for a field on object creation.
`@filterable`	Defines the filters generated for a field.
`@fulltext`	Indicates that there should be a fulltext index inserted into the database for the specified Node and its properties.
`@id`	Marks a field as the unique ID for an object type, and allows for autogeneration of IDs.
`@limit`	Used on nodes to inject values into Cypher `LIMIT` clauses.
`@mutation`	Limits the availability of Mutation operations in the library.
`@node`	Specifies the configuration of a GraphQL object type which represents a Neo4j node.
`@plural`	Redefines how to compose the plural of the type for the generated operations. This is particularly useful for types that are not correctly pluralized or are non-English words.
`@populatedBy`	Specifies a callback function that gets executed during GraphQL query parsing, to populate fields which have not been provided within the input.
`@private`	Protects fields which should only be available through the OGM.
`@query`	Limits the availability of Query operations in the library.
`@relationship`	Configure relationships between object types.
`@relationshipProperties`	Required to help you distinguish between interfaces which are used for relationship properties, and otherwise. Can only be used on interfaces, as per its definition: `"""Required to differentiate between interfaces for relationship properties, and otherwise.""" directive @relationshipProperties on INTERFACE`
`@relayId`	Specifies that the field should be used as the global node identifier for Relay.
`@selectable`	Sets the availability of fields on queries and aggregations.
`@settable`	Sets the availability of fields on the create and update inputs.
`@subscription`	Limits subscription operations in the library.
`@subscriptionsAuthorization`	Specifies authorization rules for subscriptions on the type.
`@timestamp`	Flags fields to be used to store timestamps on create/update events.
`@unique`	Indicates that there should be a uniqueness constraint in the database for the fields that it is applied to.

@alias

Maps a GraphQL schema field to a Neo4j property on a node or relationship.

@authentication

Requires authentication checks when accessing the type.

@authorization

Specifies authorization rules for queries and mutations on the type.

@coalesce

Exposes a mechanism for querying against non-existent, null values on a node.

@customResolver

Specifies that a field is resolved by a custom resolver, and allows the specification of any required fields that is passed as arguments to the custom resolver.

@cypher

Overrides field resolution (including Query and Mutation fields), instead resolving with the specified Cypher.

@default

Allows for the setting of a default value for a field on object creation.

@filterable

Defines the filters generated for a field.

@fulltext

Indicates that there should be a fulltext index inserted into the database for the specified Node and its properties.

@id

Marks a field as the unique ID for an object type, and allows for autogeneration of IDs.

@limit

Used on nodes to inject values into Cypher LIMIT clauses.

@mutation

Limits the availability of Mutation operations in the library.

@node

Specifies the configuration of a GraphQL object type which represents a Neo4j node.

@plural

Redefines how to compose the plural of the type for the generated operations. This is particularly useful for types that are not correctly pluralized or are non-English words.
