# Spiral

> Spiral loader with animated dots

A Loader component for React, Tailwind and shadcn by @turbostarter, version 1.0.0, MIT licence.

A spiral loader with dots arranged in a circle that animate to show a loading state. It uses motion animations to create a smooth, repeating effect. The dots scale and fade in a circular pattern. Use it to indicate loading in user interfaces.

## Install

```bash
npx layro-cli add @turbostarter/spiral
```

Or with shadcn: `npx shadcn@latest add https://layro.dev/r/turbostarter/spiral.json`
