# Progress Bar

Minimize visual changes that occur while your app loads content by representing each operation with a single [activity indicator](https://material.google.com/components/progress-activity.html). For example, a refresh operation should display either a refresh bar or an activity circle, but not both.

<!-- example -->
```jsx
import ProgressBar from 'react-toolbox/lib/progress_bar';

const ProgressTest = () => (
  <div>
    <ProgressBar type="circular" mode="indeterminate" />
    <ProgressBar type="linear" mode="determinate" value={83} buffer={90} />
  </div>
);
```

If you want to provide a theme via context, the component key is `RTProgressBar`.
