Ermine UI

Spinner

A small turning ring for "this is working", sized to the text around it.

See it liveSource on GitHub

Install

If this is the first component in the project, set up once. This writes ermine.json and copies the theme stylesheet. The installation guide covers Vue, Nuxt and Astro.

npx ermineui init
pnpm dlx ermineui init
yarn dlx ermineui init
bunx ermineui init

Then add the component:

npx ermineui add spinner
pnpm dlx ermineui add spinner
yarn dlx ermineui add spinner
bunx ermineui add spinner

That copies 2 files into src/components/ui/spinner/. Files you already have are kept.

Use

import { Spinner } from '@/components/ui/spinner'
<Alert variant="destructive">
  <svg>…</svg>  <!-- optional: an svg placed first becomes the icon -->
  <AlertTitle>Build failed</AlertTitle>
  <AlertDescription>Type error in cart/total.ts on line 42.</AlertDescription>
</Alert>

<Avatar src="/people/ines.jpg" alt="Ines Kovač">IK</Avatar>

<Progress :value="35" aria-label="Upload" />  <!-- leave value out when the amount is unknown -->
<Spinner />
<Button :loading="saving" @click="save">Save</Button>  <!-- a spinner, and no second press, while saving is true -->

In Nuxt, with the auto-import setting, the tags work in templates without the import. In Astro, use it inside a Vue island.

What gets copied

FileWhere it goes
Spinner.vuesrc/components/ui/spinner/Spinner.vue
index.tssrc/components/ui/spinner/index.ts

The folders are the suggested ones. ermine.json says where yours are.
