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

schemaComposer: SchemaComposer<TContext>;

Methods

get()

get(
  name: string
): GraphQLNamedType | void

set()

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

has()

has(
  name: string
): boolean

getWrapped()

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

createType()

createType(
  str: TypeDefinitionString
): GraphQLNamedType | void

parseTypesFromString()

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

parseTypesFromAst()

parseTypesFromAst(
  astDocument: DocumentNode
): TypeStorage<string, GraphQLNamedType>

convertOutputType()

convertOutputType(
  composeType: ComposeObjectType
): GraphQLObjectType

convertOutputFieldConfig()

convertOutputFieldConfig<TSource = any, TContext = any>(
  composeFC: ComposeFieldConfig<TSource, TContext>,
  fieldName: string,
  typeName: string
): GraphQLFieldConfig<TSource, TContext>

convertOutputFieldConfigMap()

convertOutputFieldConfigMap<TSource = any, TContext = any>(
  composeFields: ComposeFieldConfigMap<TSource, TContext> | GraphQLFieldConfigMap<TSource, TContext>,
  typeName: string
): GraphQLFieldConfigMap<TSource, TContext>

convertArgConfig()

convertArgConfig(
  composeAC: ComposeArgumentConfig,
  argName: string,
  fieldName: string,
  typeName: string
): GraphQLArgumentConfig

convertArgConfigMap()

convertArgConfigMap(
  composeArgsConfigMap: ComposeFieldConfigArgumentMap<any>,
  fieldName: string,
  typeName: string
): GraphQLFieldConfigArgumentMap

convertInputFieldConfig()

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

convertInputFieldConfigMap()

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

Internal type definitions

TypeDefinitionString

/**
 * Eg. `type Name { field: Int }`
 */
export type TypeDefinitionString = string;

TypeWrappedString

/**
 * Eg. `Int`, `Int!`, `[Int]`
 */
export type TypeWrappedString = string;

TypeNameString

/**
 * Eg. `Int`, `Float`
 */
export type TypeNameString = string;

TypeAsString

export type TypeAsString =
  | TypeDefinitionString
  | TypeWrappedString
  | TypeNameString;

ComposeObjectType

export type ComposeObjectType =
  | ObjectTypeComposer<any, any>
  | GraphQLObjectType
  | TypeDefinitionString
  | TypeAsString;
