@kbn/utility-types

TypeScript utility types for usage in Kibana.

• This package re-exports a subset of the items in utility-types
• You can also add more utility types here.

Usage

import { UnwrapObservable } from '@kbn/utility-types';

type A = Observable<string>;
type B = UnwrapObservable<A>; // string

Reference

• Assign<T, U> — From U assign properties to T (just like object assign).
• DotObject<T> — Convert type T to a flattened structure.
• DedotObject<T> — The inverse of DotObject<T>: convert the flattened type T to a deeply-nested type.
• Ensure<T, X> — Makes sure T is of type X.
• ObservableLike<T> — Minimal interface for an object resembling an Observable.
• PublicContract<T> — Returns an object with public keys only.
• PublicKeys<T> — Returns public keys of an object.
• RecursiveReadonly<T> — Like Readonly<T>, but freezes object recursively.
• ShallowPromise<T> — Same as Promise type, but it flat maps the wrapped type.
• UnionToIntersection<T> — Converts a union of types into an intersection.
• UnwrapObservable<T> — Returns wrapped type of an observable.
• Values<T> — Returns object or array value types.
