Basic Components

Button

Triggers an action or event when the user clicks on it. Buttons are a primary way for users to interact with the application and can contain text, an icon, or both.

Source Edit this page

Button is the primary interactive control for triggering actions. It supports the full appearance, size, shape, and variant prop matrix and renders as an <a> when given an href.

When to Use

Primary page actions, calls-to-action, and prominent affordances.
Form submissions (type="submit") and form-level reset.
Confirming or dismissing dialogs and modals.
Toolbar actions where the label adds clarity beyond an icon alone.
Cross-page navigation when the action looks like a button (otherwise prefer Link).

When NOT to Use

For inline navigation inside prose, prefer Link — it sits on the typography baseline.
For icon-only destructive actions inside a row or table cell, prefer IconButton.

Basic Usage

Each appearance prop maps to a semantic color from the active theme.

<Row flexWrap>
  <Button primary>primary</Button>
  <Button brand>brand</Button>
  <Button accent>accent</Button>
  <Button secondary>secondary</Button>
  <Button tertiary>tertiary</Button>
  <Button success>success</Button>
  <Button danger>danger</Button>
  <Button warning>warning</Button>
  <Button info>info</Button>
  <Button link>link</Button>
  <Button inherit>inherit</Button>
</Row>

Sizes

Buttons come in five sizes — xs, sm (default), md, lg, xl. Size drives font-size, padding, gap, and border-radius simultaneously via CSS variables.

<Row flexWrap>
  <Button xs>xs</Button>
  <Button sm>sm</Button>
  <Button md>md</Button>
  <Button lg>lg</Button>
  <Button xl>xl</Button>
</Row>

With Icon

Drop an icon directly inside the button — gap is on by default, so spacing is automatic.

<Row flexWrap>
  <Button><Download/> Download</Button>
  <Button success filled><Check/> Saved</Button>
  <Button danger><Trash2/> Delete</Button>
  <Button secondary>Next <ArrowRight/></Button>
</Row>

Sizes with Icon

The same size matrix paired with an inline icon.

<Row flexWrap>
  <Button xs><Star/> Extra Small</Button>
  <Button sm><Star/> Small</Button>
  <Button md><Star/> Medium</Button>
  <Button lg><Star/> Large</Button>
  <Button xl><Star/> Extra Large</Button>
</Row>

Font Weights

Buttons default to semibold. Use any of the standard weight props to override.

<Row flexWrap>
  <Button thin>Submit</Button>
  <Button extralight>Submit</Button>
  <Button light>Submit</Button>
  <Button normal>Submit</Button>
  <Button medium>Submit</Button>
  <Button semibold>Submit</Button>
  <Button bold>Submit</Button>
  <Button extrabold>Submit</Button>
  <Button black>Submit</Button>
</Row>

Border Radius Options

Button supports three border-radius styles: rounded (default), pill, and sharp.

<Row flexWrap>
  <Button pill>Subscribe</Button>
  <Button sharp>Subscribe</Button>
  <Button rounded>Subscribe</Button>
</Row>

As Link & Disabled

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

Link Button Success Link

<Row flexWrap>
  <Button href="#">Link Button</Button>
  <Button success filled href="#">Success Link</Button>
  <Button disabled>Disabled</Button>
  <Button danger filled disabled>Disabled Danger</Button>
</Row>

Next.js Link Integration

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

import Link from 'next/link';
import { Button } from '@vaneui/ui';

<Button href="/docs" tag={Link}>Documentation</Button>

Variants

Buttons can be styled as filled, outline (default), or ghost.

<Col>
  <Row flexWrap>
    <Button filled primary>primary</Button>
    <Button filled brand>brand</Button>
    <Button filled accent>accent</Button>
    <Button filled secondary>secondary</Button>
  </Row>
  <Row flexWrap>
    <Button primary>primary</Button>
    <Button brand>brand</Button>
    <Button accent>accent</Button>
    <Button secondary>secondary</Button>
  </Row>
  <Row flexWrap>
    <Button ghost primary>primary</Button>
    <Button ghost brand>brand</Button>
    <Button ghost accent>accent</Button>
    <Button ghost secondary>secondary</Button>
  </Row>
</Col>

Customizing

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

import { ThemeProvider, Button } from '@vaneui/ui';

<ThemeProvider themeDefaults={{
  button: { main: { primary: true, lg: true, filled: true } },
}}>
  <Button>Submit</Button>
</ThemeProvider>

Add prop-conditional classes with extraClasses — applied whenever the matching boolean prop is active. For compound themes like Button, nest the prop-class map under the sub-theme name (main for Button's primary surface):

import { ThemeProvider, Button } from '@vaneui/ui';

<ThemeProvider extraClasses={{
  button: {
    main: {
      primary: 'shadow-lg hover:shadow-xl transition-shadow',
      danger: 'animate-pulse',
    },
  },
}}>
  <Button primary>Glowing Primary</Button>
</ThemeProvider>
