@tito10047/vanilla-js-datepickerZero-dependency datepicker

Lightweight, accessible, fully typed TypeScript datepicker — no frameworks needed.

Zero dependencies

Pure vanilla TypeScript. No jQuery, no moment.js — ships as < 20 KB gzip.

Full keyboard navigation

Arrows move by day and week, PageUp/PageDown by month (+Shift by year), Enter/Space selects, Escape closes — and opening the calendar highlights nothing until you press a key.

Fully accessible

ARIA dialog, focus trap, live region announcements, per WCAG 2.1.

Range & multiple

Single date, date range with hover preview, or multiple independent selections.

Async onCellRender

Mark cells asynchronously (from an API) with badges, tooltips or disabled state — race-safe.

i18n ready

Built-in sk / en / cs / de locales. Register custom locales at runtime.

Themeable

CSS custom properties for light / dark / auto themes. Override any class via classNames option.
