API Reference

Provider

PropDefaultType
duration
5000
number

Time in milliseconds that each toast should remain visible for.

label
'Notification'
string

An author-localized label for each toast. Used to help screen reader users associate the interruption with a toast.

swipeDirection
'right'
'right' | 'left' | 'up' | 'down'

Direction of pointer swipe that should close the toast.

swipeThreshold
50
number

Distance in pixels that the swipe must pass before a close is triggered.

Viewport

The fixed area where toasts appear. Users can jump to the viewport by pressing a hotkey. It is up to you to ensure the discoverability of the hotkey for keyboard users.

PropDefaultType
as
'ol'
AsTag | Component

The element or component this component should render as. Can be overwrite by asChild

asChild
boolean

Change the default rendered element for the one passed as a child, merging their props and behavior.

Read our Composition guide for more details.

hotkey
['F8']
string[]

The keys to use as the keyboard shortcut that will move focus to the toast viewport.

label
'Notifications ({hotkey})'
string | ((hotkey: string) => string)

An author-localized label for the toast viewport to provide context for screen reader users when navigating page landmarks. The available {hotkey} placeholder will be replaced for you. Alternatively, you can pass in a custom function to generate the label.

Root

PropDefaultType
as
'li'
AsTag | Component

The element or component this component should render as. Can be overwrite by asChild

Examples

Custom hotkey

Override the default hotkey using the event.code value for each key from keycode.info.

html
<ToastProvider>
  ...
  <ToastViewport :hotkey="['altKey', 'KeyT']" />
</ToastProvider>

Custom duration

Customise the duration of a toast to override the provider value.

vue
<ToastRoot :duration="3000">
  <ToastDescription>Saved!</ToastDescription>
</ToastRoot>

Duplicate toasts

When a toast must appear every time a user clicks a button, use state to render multiple instances of the same toast (see below). Alternatively, you can abstract the parts to create your own imperative API.

html
<div>
  <form @submit="count++">
    ...
    <button>save</button>
  </form>

  <ToastRoot v-for="(_, index) in count" :key="index">
    <ToastDescription>Saved!</ToastDescription>
  </ToastRoot>
</div>

Animating swipe gesture

Combine --reka-toast-swipe-move-[x|y] and --reka-toast-swipe-end-[x|y] CSS variables with data-swipe="[start|move|cancel|end]" attributes to animate a swipe to close gesture. Here's an example:

html
<ToastProvider swipeDirection="right">
  <ToastRoot class="ToastRoot">...</ToastRoot>
  <ToastViewport />
</ToastProvider>
css
/* styles.css */
.ToastRoot[data-swipe='move'] {
  transform: translateX(var(--reka-toast-swipe-move-x));
}
.ToastRoot[data-swipe='cancel'] {
  transform: translateX(0);
  transition: transform 200ms ease-out;
}
.ToastRoot[data-swipe='end'] {
  animation: slideRight 100ms ease-out;
}

@keyframes slideRight {
  from {
    transform: translateX(var(--reka-toast-swipe-end-x));
  }
  to {
    transform: translateX(100%);
  }
}

Accessibility

Adheres to the aria-live requirements.

Sensitivity

Control the sensitivity of the toast for screen readers using the type prop.

For toasts that are the result of a user action, choose foreground. Toasts generated from background tasks should use background.

Foreground

Foreground toasts are announced immediately. Assistive technologies may choose to clear previously queued messages when a foreground toast appears. Try to avoid stacking distinct foreground toasts at the same time.

Background

Background toasts are announced at the next graceful opportunity, for example, when the screen reader has finished reading its current sentence. They do not clear queued messages so overusing them can be perceived as a laggy user experience for screen reader users when used in response to a user interaction.

html
<ToastRoot type="foreground">
  <ToastDescription>File removed successfully.</ToastDescription>
  <ToastClose>Dismiss</ToastClose>
</ToastRoot>

<ToastRoot type="background">
  <ToastDescription>We've just released Radix 1.0.</ToastDescription>
  <ToastClose>Dismiss</ToastClose>
</ToastRoot>

Alternative action

Use the altText prop on the Action to instruct an alternative way of actioning the toast to screen reader users.

You can direct the user to a permanent place in your application where they can action it or implement your own custom hotkey logic. If implementing the latter, use foreground type to announce immediately and increase the duration to give the user ample time.

html
<ToastRoot type="background">
  <ToastTitle>Upgrade Available!</ToastTitle>
  <ToastDescription>We've just released Radix 1.0.</ToastDescription>
  <ToastAction altText="Goto account settings to upgrade">
    Upgrade
  </ToastAction>
  <ToastClose>Dismiss</ToastClose>
</ToastRoot>

<ToastRoot type="foreground" :duration="10000">
  <ToastDescription>File removed successfully.</ToastDescription>
  <ToastAction altText="Undo (Alt+U)">
    Undo <kbd>Alt</kbd>+<kbd>U</kbd>
  </ToastAction>
  <ToastClose>Dismiss</ToastClose>
</ToastRoot>

Close icon button

When providing an icon (or font icon), remember to label it correctly for screen reader users.

html
<ToastRoot type="foreground">
  <ToastDescription>Saved!</ToastDescription>
  <ToastClose aria-label="Close">
    <span aria-hidden="true">×</span>
  </ToastClose>
</ToastRoot>
