Toast

Toast component examples

import {Toast, Frame, Page, Button} from '@shopify/polaris';
import {useState, useCallback} from 'react';

function ToastExample() {
  const [active, setActive] = useState(false);

  const toggleActive = useCallback(() => setActive((active) => !active), []);

  const toastMarkup = active ? (
    <Toast content="Message sent" onDismiss={toggleActive} />
  ) : null;

  return (
    <div style={{height: '250px'}}>
      <Frame>
        <Page title="Toast example">
          <Button onClick={toggleActive}>Show Toast</Button>
          {toastMarkup}
        </Page>
      </Frame>
    </div>
  );
}

Required components

The toast component must be wrapped in the frame component.

Best practices

Toast should:

• Be used for short messages to confirm an action
• Not go over 3 words
• Rarely be used for error messages

When to use:

• For success messages
• Only for non-critical errors that are relevant in the moment and can be explained in 3 words. For example, if there’s an internet connection issue, the toast would say, Internet disconnected.

When not to use:

• Avoid using toast for error messages. Always try to use a banner to prominently inform merchants about persistent errors.

Content guidelines

Message

Toast messages should be:

• Short and affirmative
• Written in the pattern of: noun + verb

Toast with action

Only include an action in toast if the same action is available elsewhere on the page. For example:

• If merchants need to reload a section, offer the call to action [Reload] in the toast. If they miss the toast message, they can also refresh the entire page.
• If merchants delete an image, offer the option to [Undo] the deletion. If they miss it in the toast message, they can still retrieve it from somewhere else.

Action should:

• Keep the action label short, preferably 1 verb.
• Not have actions, like [Cancel], for dismissing toast. The [X] to dismiss is already included in the component.
• Be used with a duration of at least 10,000 milliseconds for accessibility.

Related components

• To present a small amount of content or a menu of actions in a non-blocking overlay, use the popover component
• To communicate a change or condition that needs the merchant’s attention within the context of a page, use the banner component

Accessibility

The content of the toast component is implemented as an ARIA live region using aria-live="assertive". When the toast appears, screen readers will interrupt any announcement a screen reader is currently making.

Avoid using toast for critical information that merchants need to act on immediately. Toast might be difficult for merchants with low vision or low dexterity to access because it:

• Disappears automatically
• Can’t be easily accessed with the keyboard
• Might appear outside the proximity of the merchant’s current focus

To ensure that Toasts are read out by a screen reader when a Modal is open, apps should be wrapped in a Frame component.

Toast with action

Make sure that merchants can also accomplish the action in the toast another way, since the toast action may be difficult to access for some merchants. If the toast action is not available somewhere else on the page, for example a retry action that reloads a section, it should have a fallback action, for example a browser refresh.

Toast with action should persist for at least 10,000 milliseconds to give the merchant enough time to act on it.
