Measured entry

tripled-toast-notification-shadcnui

alertminimal-flatmotion on file

A client-side success toast demo shipped as a shadcn registry page. It owns its open state, dismisses itself after a fixed delay, and animates entry and exit with Framer Motion. It relies on React, Lucide icons, and local shadcn Button and Card components backed by the project's styling utilities.

Verdict

A tidy interaction sample, but not a full notification system. It mounts cleanly in the prepared harness and needs a shadcn-style setup in a bare project. Use it as a starting point when its fixed success message and local trigger match the job.

Use it if

  • You need a compact saved-success confirmation launched by a nearby action.
  • Your app already has shadcn Button and Card primitives plus the expected import aliases.
  • You want a small animated example that can be adapted into an existing notification flow.

Skip it if

  • You need a reusable toast queue, stacked messages, variants, or app-wide dispatch.
  • Notifications must be announced to assistive technology, since this toast has no live-region semantics.
  • You need configurable copy, duration, placement, or externally controlled visibility without refactoring.
  • You want to avoid adding Framer Motion for a single transient alert.

Providerno provider required in the harness

In a non-shadcn project, add React, Framer Motion, Lucide React, the shadcn Button and Card implementations, Tailwind and theme styles, the local class-merging utility, and an import alias that resolves the component and utility paths. No provider is required.
