Progress Ring

[component-header:sl-progress-ring]

Progress rings are used to show the progress of a determinate operation in a circular fashion.

<sl-progress-ring value="25"></sl-progress-ring>
import { SlProgressRing } from '@shoelace-style/shoelace/dist/react';

const App = () => (
  <SlProgressRing value="25" />
);

Examples

Size

Use the --size custom property to set the diameter of the progress ring.

<sl-progress-ring value="50" style="--size: 200px;"></sl-progress-ring>
import { SlProgressRing } from '@shoelace-style/shoelace/dist/react';

const App = () => (
  <SlProgressRing 
    value="50" 
    style={{ '--size': '200px' }}
  />
);

Track Width

Use the --track-width custom property to set the width of the progress ring's track.

<sl-progress-ring value="50" style="--track-width: 10px;"></sl-progress-ring>
import { SlProgressRing } from '@shoelace-style/shoelace/dist/react';

const App = () => (
  <SlProgressRing 
    value="50" 
    style={{ '--track-width': '10px' }}
  />
);

Colors

To change the color, use the --track-color and --indicator-color custom properties.

<sl-progress-ring 
  value="50" 
  style="
    --track-color: pink; 
    --indicator-color: deeppink;
  "
></sl-progress-ring>
import { SlProgressRing } from '@shoelace-style/shoelace/dist/react';

const App = () => (
  <SlProgressRing 
    value="50" 
    style={{ 
      '--track-color': 'pink',
      '--indicator-color': 'deeppink'
    }}
  />
);

Labels

Use the label attribute to label the progress ring and tell assistive devices how to announce it.

<sl-progress-ring value="50" label="Upload progress"></sl-progress-ring>
import { SlProgressRing } from '@shoelace-style/shoelace/dist/react';

const App = () => (
  <SlProgressRing 
    value="50" 
    label="Upload progress"
  />
);

Showing Values

Use the default slot to show a label inside the progress ring.

<sl-progress-ring value="50" class="progress-ring-values" style="margin-bottom: .5rem;">50%</sl-progress-ring>

<br>

<sl-button circle><sl-icon name="dash"></sl-icon></sl-button>
<sl-button circle><sl-icon name="plus"></sl-icon></sl-button>

<script>
  const progressRing = document.querySelector('.progress-ring-values');
  const subtractButton = progressRing.nextElementSibling.nextElementSibling;
  const addButton = subtractButton.nextElementSibling;

  addButton.addEventListener('click', () => {
    const value = Math.min(100, progressRing.value + 10);
    progressRing.value = value;
    progressRing.textContent = `${value}%`;
  });

  subtractButton.addEventListener('click', () => {
    const value = Math.max(0, progressRing.value - 10)
    progressRing.value = value;
    progressRing.textContent = `${value}%`;
  });
</script>
import { useState } from 'react';
import { 
  SlButton,
  SlIcon,
  SlProgressRing
} from '@shoelace-style/shoelace/dist/react';

const App = () => {
  const [value, setValue] = useState(50);

  function adjustValue(amount) {
    let newValue = value + amount;
    if (newValue < 0) newValue = 0;
    if (newValue > 100) newValue = 100;
    setValue(newValue);
  }

  return (
    <>
      <SlProgressRing 
        value={value} 
        style={{ marginBottom: '.5rem' }}
      >
        {value}%
      </SlProgressRing>

      <br />

      <SlButton circle onClick={() => adjustValue(-10)}>
        <SlIcon name="dash" />
      </SlButton>

      <SlButton circle onClick={() => adjustValue(10)}>
        <SlIcon name="plus" />
      </SlButton>
    </>
  );
