The HTTP Feature-Policy header gamepad directive controls whether the current document is allowed to use the Gamepad API. When this policy is disabled, calls to Navigator.getGamepads() will throw a SecurityError DOMException. In addition, the gamepadconnected and gamepaddisconnected events will not fire.
Feature-Policy: gamepad <allowlist>;
A list of origins for which the feature is allowed. See Feature-Policy.
Default allow list for gamepad is 'self'.
SecureCorp Inc. wants to disable the Gamepad API within all browsing contexts except for its own origin and those whose origin is https://example.com. It can do so by delivering the following HTTP response header to define a feature policy:
Feature-Policy: gamepad 'self' https://example.com
FastCorp Inc. wants to disable gamepad for all cross-origin child frames, except for a specific <iframe>. It can do so by delivering the following HTTP response header to define a feature policy:
Feature-Policy: gamepad 'self'
Then include an allow attribute on the <iframe> element:
<iframe src="https://other.com/game" allow="gamepad"></iframe>
iframe attributes can selectively enable features in certain frames, and not in others, even if those frames contain documents from the same origin.
