Measured entry

shadcn-sonner

alertunclassifiedmotion on file

A client-side Toaster wrapper around Sonner that follows shadcn's New York styling. It reads the active theme through next-themes, supplies status icons from lucide-react, and maps toast colors and rounding to shadcn CSS variables while forwarding standard Sonner props.

Verdict

A dependable adapter for teams already using shadcn tokens, Sonner, and next-themes. It builds and mounts cleanly without a provider in the harness, but the narrow viewport overflow deserves attention before shipping on mobile.

Use it if

  • You want Sonner notifications to inherit an existing shadcn theme and token set.
  • You need a small wrapper that standardizes success, info, warning, error, and loading icons.
  • Your app already uses next-themes and can mount one shared toaster near the application root.

Skip it if

  • Your narrow mobile layout cannot tolerate the observed horizontal overflow without additional testing or overrides.
  • You do not use next-themes and want to avoid carrying a theme dependency for a toast wrapper.
  • You need a fully custom notification system rather than Sonner's behavior and public API.

In a non-shadcn project, add sonner, next-themes, and lucide-react; configure a next-themes provider if the application needs live theme switching; define the popover, foreground, border, and radius CSS variables; and provide equivalents for the Tailwind utility classes used by the wrapper.
