Documentation

You should check out the full documentation for live examples and more customization information, but an example usage is shown below.

Usage

The majority of the time you'll be using the progress components to track some long running task or initial page loading. For accessibility, you'll need to add an id to the progress component as well as updating the main loading area to have aria-buys="true" and aria-describedby="PROGRESS_ID":

import { render } from "react-dom";
import { CircularProgress, LinearProgress } from "@react-md/progress";
import { Typography } from "@react-md/typography";
import { useToggle } from "@react-md/utils";

const App = () => {
  const [loadingCircle, , stopLoadingCircle] = useToggle(true);
  const [loadingLinear, , stopLoadingLinear] = useToggle(true);

  useEffect(() => {
    let circleTimeout = window.setTimeout(() => {
      stopLoadingCircle();
      circleTimeout = undefined;
    }, 5000);

    let linearTimeout = window.setTimeout(() => {
      stopLoadingLinear();
      linearTimeout = undefined;
    }, 8000);

    return () => {
      window.clearTimeout(circleTimeout);
      window.clearTimeout(linearTimeout);
    };
  }, []);

  return (
    <>
      <div
        id="circle-content"
        aria-busy={loadingCircle || undefined}
        aria-describedby={loadingCircle ? "circular-progress" : undefined}
      >
        {loadingCircle && <CircularProgress id="circular-progress" />}
        {!loadingCircle && (
          <Typography type="headline-2">Hello from circle div</Typography>
        )}
      </div>
      <div
        id="linear-content"
        aria-busy={loadingLinear || undefined}
        aria-describedby={loadingCircle ? "circular-progress" : undefined}
      >
        {loadingLinear && <CircularProgress id="linear-progress" />}
        {!loadingLinear && (
          <Typography type="headline-2">Hello from linear div</Typography>
        )}
      </div>
    </>
  );
};

render(<App />, document.getElementById("root"));
