@delightstack/utilities

Framework-agnostic TypeScript utilities shared across the Delightstack packages — the DelightError error class, reactive helpers, attachments, and DOM utilities.

Install

pnpm add @delightstack/utilities

The reactive helpers and attachments use Svelte 5 runes, so svelte is an optional peer dependency (only required if you import those entry points).

Error handling

DelightError is the single operational error class used by every Delightstack package.

import { DelightError } from '@delightstack/utilities';

throw DelightError.badRequest('Invalid input'); // 400
throw DelightError.unauthorized('Not authenticated'); // 401
throw DelightError.notFound('Resource not found'); // 404

// Full options
throw new DelightError({ message: 'Boom', status: 500, code: 'INTERNAL_ERROR' });

// Normalize unknowns + serialize
const err = DelightError.from(unknown);
return err.toResponse(); // → Response
