How to Fix Geolocation Permission Denied in React

Stumped by a Geolocation Permission Denied in React? This error is more common than you'd think, and the fix is usually simple.

Why This Happens

Geolocation Permission Denied fires when the user or browser blocks location access. This happens when the page isn't served over HTTPS, the user clicked 'Deny' on the permission prompt, or browser privacy settings restrict location APIs.

How to Fix It

The key is to handle PERMISSION_DENIED gracefully with a user-friendly fallback message:

function useGeolocation() {
  const [coords, setCoords] = useState(null);
  const [error, setError] = useState(null);

  useEffect(() => {
    if (!navigator.geolocation) {
      setError("Geolocation not supported");
      return;
    }
    navigator.geolocation.getCurrentPosition(
      (pos) => setCoords(pos.coords),
      (err) => {
        if (err.code === err.PERMISSION_DENIED) {
          setError("Enable location access in browser settings");
        } else {
          setError("Unable to get location");
        }
      },
      { timeout: 10000 }
    );
  }, []);

  return { coords, error };
}

Common Pitfall

When debugging this, start by reproducing the exact error message. Slight variations in the error text can point to completely different root causes in React. If you're using Docker or a containerized setup, make sure the fix is reflected in both your local and production Dockerfiles.

Testing Your Changes

Run your test suite to make sure the fix doesn't introduce regressions. If you don't have tests covering this area, now is a good time to add a simple integration test. A quick manual smoke test across different browsers or environments can also catch edge cases your tests might miss.

Monitoring

Consider integrating [Bugsly](https://bugsly.dev) into your React workflow to catch, track, and resolve errors like this automatically.
