Examples

Detecting available WebXR session features

The XRSystem.requestSession() method allows you to request XR session features. The features can be requested either as requiredFeatures (the XRSession must support the feature), or as optionalFeatures (the XRSession may support the feature). The enabledFeatures property identifies which features are actually available in the session.

navigator.xr
  .requestSession("immersive-ar", {
    requiredFeatures: ["local", "hit-test"],
    optionalFeatures: ["anchors"],
  })
  .then((xrSession) => {
    // Log enabledFeatures
    console.log(xrSession.enabledFeatures);

    // Check if anchors can be used
    if (xrSession.enabledFeatures.includes("anchors")) {
      // Go ahead and set up anchors
    }
  });
