Measured entry

kibo-banner

chatminimal-flat

A composable client-side React announcement banner with optional icon, action, inset styling, and dismiss control. It ships as shadcn registry source and relies on Tailwind theme classes, a local shadcn Button and cn utility, Radix controllable state, and Lucide icons.

Verdict

A sound, flexible announcement primitive that builds, mounts, and adapts cleanly in the prepared harness. It needs a shadcn-style setup because the bare project cannot resolve its local utility import. The chat label is misleading; this is a dismissible banner, not a messaging component.

Use it if

  • You need a full-width notice with an action and optional dismissal.
  • Your app already uses shadcn conventions and Tailwind theme tokens.
  • You need controlled or uncontrolled banner visibility.

Skip it if

  • You need dismissal to persist across navigation or sessions without adding storage logic.
  • Your project does not use Tailwind or shadcn-style local component aliases.
  • You need a chat message, conversation thread, or live-message behavior rather than an announcement strip.

In a non-shadcn project, add the local Button component and cn class-merging utility, configure the at-sign path alias, provide the Tailwind theme tokens used by the styles, and install the Radix controllable-state and Lucide packages.
