I tried implementing expo-camera on a web application, but it returns:
CameraManager.requestPermissionsAsync is not a function
I also tried to preview the snack on the expo-camera docs, and there is the same error.

I’m not sure it’s the “right” way to do this, but I did the following:
if (Platform.OS.toLowerCase() === "web") {
setHasPermission(true);
} else {
const { status } = await BarCodeScanner?.requestPermissionsAsync();
setHasPermission(status === "granted");
}
Actually, I found the right way to do this. For the web, you need to uses the Permissions
module.
Something like this:
const [permission, askPermission] = Permissions.usePermissions(
Permissions.CAMERA,
);
...
useEffect(() => {
if (permission?.permissions?.camera?.granted) {
setShowBarCodeScanner(true);
} else {
askPermission();
}
}, [permission?.permissions?.camera, setShowBarCodeScanner, askPermission]);
