# 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<HasSomeOptions, 'bar' | 'baz'>;
```
The `MoreRequired` type is like `HasSomeOptionals`, but `bar` and `baz` are now required rather than optional. `quux` remains optional.
