allowLegacyFragmentVariables

• Optional allowLegacyFragmentVariables: boolean

Deprecated

will be removed in the v17.0.0

If enabled, the parser will understand and parse variable definitions contained in a fragment definition. They’ll be represented in the variableDefinitions field of the FragmentDefinitionNode.

The syntax is identical to normal, query-defined variables. For example:

fragment A($var: Boolean = false) on T {
  ...
}

Inherited from

ParseOptions.allowLegacyFragmentVariables

Defined in

node_modules/graphql/language/parser.d.ts:90

commentDescriptions

• Optional commentDescriptions: boolean

Descriptions are defined as preceding string literals, however an older experimental version of the SDL supported preceding comments as descriptions. Set to true to enable this deprecated behavior. This option is provided to ease adoption and will be removed in v16.

Default: false

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:56 

consistentEnumMerge

• Optional consistentEnumMerge: boolean

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:78 

convertExtensions

• Optional convertExtensions: boolean

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:77 

exclusions

• Optional exclusions: string[]

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:75 

forceSchemaDefinition

• Optional forceSchemaDefinition: boolean

Creates schema definition, even when no types are available Produces: schema { query: Query }

Default: false

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:41 

ignoreFieldConflicts

• Optional ignoreFieldConflicts: boolean

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:79 

maxTokens

• Optional maxTokens: number

Parser CPU and memory usage is linear to the number of tokens in a document however in extreme cases it becomes quadratic due to memory exhaustion. Parsing happens before validation so even invalid queries can burn lots of CPU time and memory. To prevent this you can set a maximum number of tokens allowed within a document.

Inherited from

ParseOptions.maxTokens

Defined in

node_modules/graphql/language/parser.d.ts:74

noLocation

• Optional noLocation: boolean

By default, the parser creates AST nodes that know the location in the source that they correspond to. This configuration flag disables that behavior for performance or testing.

Inherited from

ParseOptions.noLocation

Defined in

node_modules/graphql/language/parser.d.ts:66

onFieldTypeConflict

• Optional onFieldTypeConflict: OnFieldTypeConflict

Called if types of the same fields are different

Default: false

@example: Given:

 type User { a: String }
 type User { a: Int }

Instead of throwing already defined with a different type error, onFieldTypeConflict function is called.

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:95 

pathToDirectivesInExtensions

• Optional pathToDirectivesInExtensions: string[]

Inherited from

GetDocumentNodeFromSchemaOptions.pathToDirectivesInExtensions

Defined in

packages/utils/src/types.ts:23 

reverseArguments

• Optional reverseArguments: boolean

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:96 

reverseDirectives

• Optional reverseDirectives: boolean

Puts the next directive first.

Default: false

@example: Given:

 type User { a: String @foo }
 type User { a: String @bar }

Results:

 type User { a: @bar @foo }

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:74 

sort

• Optional sort: boolean | CompareFn<string>

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:76 

throwOnConflict

• Optional throwOnConflict: boolean

Throws an error on a merge conflict

Default: false

Defined in

packages/merge/src/typedefs-mergers/merge-typedefs.ts:47 

useSchemaDefinition

• Optional useSchemaDefinition: boolean

Produces schema { query: ..., mutation: ..., subscription: ... }

Default: true
