@luminelabs/toolkit

⚠️ Experimental / Internal Use

Primarily intended for personal and internal use. It may change, break, or be restructured at any time. Don't rely on it for public projects unless you're prepared to maintain your own fork. Issues/feature requests may be closed without response.

Small, framework-free TypeScript primitives. ESM-only. Ships types.

Install

npm install @luminelabs/toolkit

Peer-free; pulls in es-toolkit as its only runtime dependency (tree-shakeable).

What's inside

Everything is re-exported from the package root. Source is organised by domain under src/:

• async/ — LinkedAbortController (chains an AbortController to parent signals).
• dom/ — createFileList (the DataTransfer trick for populating a file input), getTextWidth, isIFrame, observeResize + extractEntrySize (one shared ResizeObserver per box type, refcounted).
• errors/ — tc (error-first [error, value] result tuples over es-toolkit's attempt, plus syncSafe/asyncSafe with an onError callback), assertNever.
• object/ — shallowEqual (one-level equality with an optional per-key comparator).
• pubsub/ — EventBus (typed event map), createKeyedStore (refcounted per-key subscription store with an onActive resource lifecycle).
• string/ — maskString, sortStrings.
• types/ — Enum (const-object enum helper + Enum<T> type), DeepPartial.

import { EventBus, tc, Enum } from "@luminelabs/toolkit"

For anything not covered here, reach for es-toolkit directly — this package deliberately doesn't re-wrap what it already does well.
