Core.TS

@fest-lib/core — level 0.5 fest-lib utilities. No fest peers. Used by every higher library.

Unwraps refs (getValue), type/empty checks, deferred promises, channels, mapped collections, user-scope paths, time/phone helpers, grid item math, WeakRef wrappers, and DOM constructor polyfills for worker/Node hosts.

Install

npm install @fest-lib/core

import { getValue, isObject, createDeferred, debounce } from "@fest-lib/core";

const raw = getValue(maybeRef);
const { promise, resolve } = createDeferred<string>();
