Rating

Star rating input — interactive or read-only, with optional half stars.

Import

tsx

import { Rating } from "@cronus-ui/ui";

bash

npx cronus-ui add rating

Examples

Interactive

A controlled star rating. Click or use the arrow keys to set the value; the wrapper is a single focusable slider so it stays keyboard- and screen-reader-friendly.

3 stars

tsx

function RatingDemo() {
  const [value, setValue] = useState(3);

  return (
    <div className="flex flex-col items-center gap-3">
      <Rating value={value} onValueChange={setValue} aria-label="Rate your experience" />
      <p className="text-sm text-fg-secondary tabular-nums">
        {value} {value === 1 ? "star" : "stars"}
      </p>
    </div>
  );
}

Read-only with a count

Display an aggregate score with `readOnly` and `allowHalf`, paired with the review count.
