Flatpickr

Flatpickr is a lightweight, dependency-free JavaScript datetime picker library, currently stable at version 4.6.13. It offers a rich set of features for date and time input, including range selections, multiple date selections, time-only pickers, and highly customizable date disabling logic. The library maintains an active release cadence, frequently publishing patch versions to address bugs and introduce minor enhancements, as seen in the recent 4.6.x releases. Unlike many alternatives, Flatpickr avoids heavy dependencies like jQuery or Moment.js, contributing to smaller bundle sizes. It provides 51 locales, 8 themes, and a plugin architecture, with official and community-maintained wrappers for popular frameworks like React, Angular, and Vue. Its primary differentiator is providing extensive functionality and a polished user experience without sacrificing performance or introducing external bloat.
