Star Rating
A real radio group under the stars, so arrows, Tab and screen readers work as for any radio group. Hover previews, a second press clears, half stars with precision 0.5, and a read-only average with its count.
The decision inside it
Read-only is one sentence
A shown rating is one image named "Rated 4.5 out of 5, 1,284 ratings", not five stars a screen reader has to count.
When to use it
Use Star Rating to collect a score out of five, or show one readOnly with a count. precision={0.5} allows half stars. For a yes/no reaction use Reaction Bar.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's Star Rating for this.
Install it: npx shadcn@latest add @layro/star-rating
(the @layro registry is set up in components.json, with LAYRO_KEY in .env.local)
Import it from @/components/ui/star-rating.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Free components install through the @layro registry with your CLI token: see the Namespaced tab.
Usage
import { StarRating } from "@/components/ui/star-rating";
export function ReviewScore({ score, setScore }: { score: number; setScore: (n: number) => void }) {
return (
<div className="flex flex-col gap-3">
<StarRating aria-label="Your rating" value={score} onValueChange={setScore} />
<StarRating readOnly value={4.5} precision={0.5} showValue count={128} size="sm" />
</div>
);
