TypeScript utilities, refined

Focused modules for strings, objects, async, DOM, event bus, cache storage, and deep clone/equality. Zero dependencies. Tree-shakeable. Fully typed.

Fully Typed

Strict TypeScript across every module. Literal types are preserved through helpers like capitalize, and type guards narrow properly.

Ships ESM, CJS, and per-module subpath exports. Import only what you use - sideEffects:false tells your bundler it's safe.

No runtime deps. React is a peer dependency and is only needed for the optional useEventBus hook.

Handles Dates, Maps, Sets, TypedArrays, Buffers, class instances, circular references, getters/setters, and symbols.

Cross-component event bus with typed topics and payloads. Auto-cleanup via the React hook. Custom error handler + once-subscription included.

Thin wrapper over the browser Cache API with BigInt-safe JSON serialization and optional TTL storage.
