ErrorResultUnion

@vendure/core Source

Used to construct a TypeScript return type for a query or mutation which, in the GraphQL schema, returns a union type composed of a success result (e.g. Order) plus one or more ErrorResult types.

Since the TypeScript entities do not correspond 1-to-1 with their GraphQL type counterparts, we use this type to substitute them.

Example

type UpdateOrderItemsResult = Order | OrderModificationError | OrderLimitError | NegativeQuantityError;type T1 = ErrorResultUnion<UpdateOrderItemsResult, VendureEntityOrder>;// T1 = VendureEntityOrder | OrderModificationError | OrderLimitError | NegativeQuantityError;

Signature

type ErrorResultUnion<T extends GraphQLErrorResult | U, E extends VendureEntity, U = any> = | JustErrorResults<T>    | E
