Basic Components

IconButton

A square icon-only button with customizable appearance, size, and shape. Supports loading state and renders as anchor when href is provided.

Basic usage

Drop an icon directly inside the IconButton. Each appearance prop maps to a semantic color from the active theme.

<Row flexWrap>
  <IconButton aria-label="Favorite"><Star /></IconButton>
  <IconButton secondary aria-label="Like"><Heart /></IconButton>
  <IconButton success aria-label="Confirm"><Check /></IconButton>
  <IconButton danger aria-label="Delete"><Trash2 /></IconButton>
  <IconButton warning aria-label="Notifications"><Bell /></IconButton>
  <IconButton info aria-label="Show info"><Info /></IconButton>
</Row>

Accessibility

An icon-only button has no visible text, so assistive technology has nothing to announce. Give every IconButton an accessible name with aria-label.

<Row flexWrap>
  <IconButton aria-label="Add to favorites"><Star /></IconButton>
  <IconButton secondary aria-label="Like"><Heart /></IconButton>
  <IconButton danger aria-label="Delete"><Trash2 /></IconButton>
</Row>

Sizes

IconButton supports five sizes: xs, sm (default), md, lg, xl. Size drives the button's dimensions, padding, and border-radius; the aspect ratio stays square at every size.

<Row flexWrap itemsEnd>
  <Col itemsCenter>
    <IconButton xs><Star /></IconButton>
    <Text sm secondary>xs</Text>
  </Col>
  <Col itemsCenter>
    <IconButton sm><Star /></IconButton>
    <Text sm secondary>sm</Text>
  </Col>
  <Col itemsCenter>
    <IconButton md><Star /></IconButton>
    <Text sm secondary>md</Text>
  </Col>
  <Col itemsCenter>
    <IconButton lg><Star /></IconButton>
    <Text sm secondary>lg</Text>
  </Col>
  <Col itemsCenter>
    <IconButton xl><Star /></IconButton>
    <Text sm secondary>xl</Text>
  </Col>
</Row>

Variants

IconButton renders as outline (default) or filled.

<Col>
  <Row flexWrap>
    <IconButton><Star /></IconButton>
    <IconButton secondary><Heart /></IconButton>
    <IconButton success><Check /></IconButton>
    <IconButton danger><Trash2 /></IconButton>
    <IconButton warning><Bell /></IconButton>
    <IconButton info><Info /></IconButton>
  </Row>
  <Row flexWrap>
    <IconButton filled><Star /></IconButton>
    <IconButton filled secondary><Heart /></IconButton>
    <IconButton filled success><Check /></IconButton>
    <IconButton filled danger><Trash2 /></IconButton>
    <IconButton filled warning><Bell /></IconButton>
    <IconButton filled info><Info /></IconButton>
  </Row>
</Col>

Shapes

IconButton supports rounded (default), pill, and sharp. pill is especially well suited to icon-only buttons.

rounded

pill

sharp

<Row flexWrap>
  <Col itemsCenter>
    <IconButton filled><Star /></IconButton>
    <Text sm secondary>rounded</Text>
  </Col>
  <Col itemsCenter>
    <IconButton pill filled><Star /></IconButton>
    <Text sm secondary>pill</Text>
  </Col>
  <Col itemsCenter>
    <IconButton sharp filled><Star /></IconButton>
    <Text sm secondary>sharp</Text>
  </Col>
</Row>

As Link and disabled

Pass href to render the IconButton as an <a> for navigation. Use disabled to prevent interaction.

<Row flexWrap>
  <IconButton href="https://github.com" target="_blank"><ExternalLink /></IconButton>
  <IconButton filled success href="#"><ExternalLink /></IconButton>
  <IconButton disabled><Star /></IconButton>
  <IconButton filled danger disabled><Trash2 /></IconButton>
</Row>

Next.js Link integration

Use the tag prop to render the IconButton as a Next.js Link for client-side navigation.

import Link from 'next/link';
import { IconButton } from '@vaneui/ui';
import { Settings } from 'react-feather';

<IconButton href="/settings" tag={Link}><Settings /></IconButton>

Loading state

Set loading to replace the icon with a spinner and auto-disable the button.

<Row flexWrap itemsCenter>
  <IconButton loading aria-label="Refreshing"><RefreshCw /></IconButton>
  <IconButton loading filled danger aria-label="Deleting"><Trash2 /></IconButton>
  <IconButton loading lg aria-label="Saving"><Star /></IconButton>
</Row>

The ring is the Spinner component, sized from the button and coloured by the button's own text colour, so it reads correctly on every variant. Keep the aria-label describing the action: the button carries aria-busy while it spins, and the Spinner itself is decorative here.

const [loading, setLoading] = useState(false);

return (
  <IconButton loading={loading} onClick={() => setLoading(true)} aria-label="Favorite">
    <Star />
  </IconButton>
);

Customizing

Set app-wide IconButton defaults with ThemeProvider's themeDefaults:

<ThemeProvider themeDefaults={{
  iconButton: { secondary: true, pill: true, lg: true },
}}>
  <IconButton><Star /></IconButton>
</ThemeProvider>
