Permissions-Policy: gamepad
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The HTTP Permissions-Policy
header gamepad
directive controls whether the current document is allowed to use the Gamepad API.
Specifically, where a defined policy blocks use of this feature, calls to Navigator.getGamepads()
will throw a SecurityError
DOMException
. In addition, the gamepadconnected
and gamepaddisconnected
events will not fire.
Syntax

<allowlist>
-
A list of origins for which permission is granted to use the feature. See
Permissions-Policy
> Syntax for more details.
Default policy
The default allowlist for gamepad
is self

Examples
General example
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 Permissions Policy:
Permissions-Policy: gamepad=(self "https://example.com")
With an <iframe> element
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 Permissions Policy:
Permissions-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.
