# Button
Buttons are UI elements that users can interact with to perform actions. Funkwhale uses buttons in many contexts.
| Prop | Data type | Required? | Default | Description |
| -------------- | --------- | --------- | ------- | ---------------------------------------------- |
| `shadow` | Boolean | No | `false` | Whether to render the button with a shadow |
| `round` | Boolean | No | `false` | Whether to render the button as a round button |
| `icon` | String | No | | The icon attached to the button |
| `aria-pressed` | Boolean | No | `false` | Whether the button is in an active state |
| `is-loading` | Boolean | No | `false` | Whether the button is in a loading state |
In addition, use [Colors] and [Variants]
## Button colors
Buttons come in different types depending on the type of action they represent.

```vue-html

</Button>
```
<Button primary>

</Button>
### Secondary

```vue-html

## Button variants
Buttons come in different styles that you can use depending on the location of the button.
### Solid
Solid buttons have a filled background. Use these to emphasize the action the button performs.
::: info
This is the default style. If you don't specify a style, a solid button is rendered.
:::
```vue-html
<Button>
Filled button
</Button>
<Button solid>
Also filled button
</Button>
```
<Button>
Filled button
</Button>
<Button solid>
Also filled button
</Button>
### Outline
Outline buttons have a transparent background. Use these to deemphasize the action the button performs.
```vue-html
<Button outline secondary>
Outline button
</Button>
```
<Button outline secondary>
Outline button
</Button>
### Ghost
Ghost buttons have a transparent background and border. Use these to deemphasize the action the button performs.
```vue-html

```

</Button>
## Button shapes
You can choose different shapes for buttons depending on their location and use.
### Normal
Normal buttons are slightly rounded rectangles.
::: info
This is the default shape. If you don't specify a type, a normal button is rendered.
:::
```vue-html

</Button>
```
<Button>

</Button>
### Round
Round buttons have fully rounded edges.
```vue-html
<Button round>

</Button>
```
<Button round>

</Button>
## Button states
You can pass a state to indicate whether a user can interact with a button.
### Active
You can force an active state by passing an `aria-pressed` prop.
This can be useful for toggle buttons (if you don't want to use a [Toggle component](toggle))
```vue-html
<Button aria-pressed>
Active button
</Button>
```
**Secondary (default):**
<Button>
Inactive button
</Button>
<Button aria-pressed>
Active button
</Button>
---
**Primary:**
<Button primary>
Inactive button
</Button>
<Button primary aria-pressed>
Active button
</Button>
### Disabled
Disabled buttons are non-interactive and inherit a less bold color than the one provided. You can apply a disabled state by passing a `disabled` prop.
```vue-html
<Button disabled>
Disabled button
</Button>
```
<Button disabled>
Disabled button
</Button>
### Loading
If a user can't interact with a button until something has finished loading, you can add a spinner by passing the `is-loading` prop.
```vue-html
<Button is-loading>
Loading button
</Button>
```
<Button is-loading>
Loading button
</Button>
### Promise handling in `@click`
When a function passed to `@click` returns a promise, the button automatically toggles a loading state on click. When the promise resolves or is rejected, the loading state turns off.
::: danger
There is no promise rejection mechanism implemented in the `<Button>` component. Make sure the `@click` handler never rejects.
:::
```vue
<script setup lang="ts">
const click = () => new Promise((resolve) => setTimeout(resolve, 1000));
</script>
<template>
<Button @click="click"> Click me </Button>
</template>
```
<Button @click="click">
Click me
</Button>
You can override the promise state by passing a false `is-loading` prop.
```vue-html
<Button :is-loading="false">
Click me
</Button>
```
<Button :is-loading="false">
Click me
</Button>
## Icons
You can use [Bootstrap Icons](https://icons.getbootstrap.com/) in your button component
::: info
Icon buttons shrink down to the icon size if you don't pass any content. If you want to keep the button at full width with just an icon, add `&nbsp;` into the slot.
:::
```vue-html
<Button color="secondary" icon="bi-three-dots-vertical" />
<Button color="secondary" is-round icon="bi-x" />
<Button icon="bi-save" />
<Button color="destructive" icon="bi-trash">
Delete
</Button>
```
<Button icon="bi-three-dots-vertical" />
<Button round icon="bi-x" />
<Button primary icon="bi-save" width="standard" />
<Button destructive icon="bi-trash">
Delete
</Button>
## Width and alignment
<Layout flex>
```vue-html
<Button width="auto">·</Button>
<Button width="standard">·</Button>
<Button width="full">·</Button>
