# WithRequired type This package defines the TypeScript utility type `WithRequired`. It transforms a type that has one or more optional fields into a type where those fields are required. For example: ``` import { WithRequired } from '@apollo/utils.withrequired'; interface HasSomeOptionals { foo: number; bar?: string; baz?: boolean; quux?: string; } type MoreRequired = WithRequired; ``` The `MoreRequired` type is like `HasSomeOptionals`, but `bar` and `baz` are now required rather than optional. `quux` remains optional.
