Working with this library

Checked 2026-10-21 against official website/docs/repository. MIT source verified in halfmoonui/halfmoon. Install halfmoon and import halfmoon/css/halfmoon.min.css, or use the documented downloadable CSS. It supplies no halfmoon.js: use bootstrap.bundle.js for interactive behavior. Official documentation describes compatibility with Bootstrap component wrappers; that does not make this a separate native React, Vue, Angular or Svelte component implementation. Current homepage shows v2.0.2; repository is not archived but its latest recorded push is December 2024, so review maintenance and Bootstrap-version compatibility before adopting. Editorial: useful for existing Bootstrap dashboards that need CSS-variable themes rather than a framework migration. Do not assume source drop-in claims cover every third-party plugin or custom override. Sponsorship/ads are not required library fees; no paid core plan found.
