  npm registry metadata for the @tui scope (registry.npmjs.org), probed 2026-07-28, plus every
  documentation page on https://developer.tui.

  TUI publishes no embeddable components for API partners — there is no hosted booking widget, no
  drop-in search element, no embedded dashboard and no JS loader offered anywhere on developer.tui.
  What TUI does publish, and publishes openly on the public npm registry, is its internal front-end
  design system: a CSS library plus an Atomico-based web-component set that powers TUI's consumer
  websites. This is recorded because the packages are genuinely first-party, genuinely public and
  genuinely client-side components — but their audience is TUI's own web teams, not the partners who
  integrate the 21 API products. Nothing here is documented on the developer portal or referenced
  from any API product page.

          TUI's fork of the Cally date-picker custom elements (WickyNilliams/cally), built on
          Atomico. The only true web-component package in the set — relevant to travel because the
          date range picker is the core of a holiday search UI.
