TypeMapper

Type storage and type generator from Schema Definition Language (SDL). This is slightly rewritten buildASTSchema utility from graphql-js that allows to create type from a string (SDL).

Properties

schemaComposer

Current SchemaComposer instance which is used for getting types by name for type creation via SDL.

static schemaComposer: SchemaComposer;

Methods

get()

get(
  name: string
): GraphQLNamedType | null;

set()

set(
  name: string,
  type: GraphQLNamedType
): void;

has()

has(
  name: string
): boolean;

getWrapped()

getWrapped(
  str:
   | TypeWrappedString
   | TypeNameString
): GraphQLType | null;

createType()

createType(
  str: TypeDefinitionString
): GraphQLNamedType | null;

parseTypesFromString()

parseTypesFromString(
  str: string
): TypeStorage<GraphQLNamedType>;

parseTypesFromAst()

parseTypesFromAst(
  astDocument: DocumentNode
): TypeStorage<GraphQLNamedType>;

convertOutputFieldConfig()

convertOutputFieldConfig<TSource, TContext>(
  composeFC: ComposeFieldConfig<TSource, TContext>,
  fieldName?: string,
  typeName?: string
): GraphQLFieldConfig<TSource, TContext>;

convertOutputFieldConfigMap()

convertOutputFieldConfigMap<TSource, TContext>(
  composeFields:
    | ComposeFieldConfigMap<TSource, TContext>
    | GraphQLFieldConfigMap<TSource, TContext>,
  typeName?: string
): GraphQLFieldConfigMap<TSource, TContext>;

convertArgConfig()

convertArgConfig(
  omposeAC: ComposeArgumentConfig,
  argName?: string,
  fieldName?: string,
  typeName?: string
): GraphQLArgumentConfig;

convertArgConfigMap()

convertArgConfigMap(
  composeArgsConfigMap: ComposeFieldConfigArgumentMap,
  fieldName?: string,
  typeName?: string
): GraphQLFieldConfigArgumentMap;

convertInputFieldConfig()

convertInputFieldConfig(
  composeIFC: ComposeInputFieldConfig,
  fieldName?: string,
  typeName?: string
): GraphQLInputFieldConfig;

convertInputFieldConfigMap()

convertInputFieldConfigMap(
  composeFields: ComposeInputFieldConfigMap,
  typeName?: string
): GraphQLInputFieldConfigMap;

Internal type definitions

Flowtype definitions which are used in this class.

TypeDefinitionString

type TypeDefinitionString = string; // eg type Name { field: Int }

TypeWrappedString

type TypeWrappedString = string; // eg. Int, Int!, [Int]

TypeNameString

type TypeNameString = string; // eg. Int, Float

TypeAsString

type TypeAsString = TypeDefinitionString | TypeWrappedString | TypeNameString;
