This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The Permissions interface of the Permissions API provides the core Permission API functionality, such as methods for querying and revoking permissions

Methods

Permissions.query()
Returns the user permission status for a given API.
Permissions.request()
Requests permission to use a given API. This is not currently supported in any browser.
Permissions.revoke()
Revokes the permission currently set on a given API.

Example

navigator.permissions.query({name:'geolocation'}).then(function(result) {
  if (result.state == 'granted') {
    showLocalNewsWithGeolocation();
  } else if (result.state == 'prompt') {
    showButtonToEnableLocalNews();
  }
  // Don't do anything if the permission was denied.
});

[1] Starting in Firefox 51, revoke() is only available if the preference dom.permissions.revoke.enable is true. It is false by default. This was done because there are discussions ongoing about the design of this method, and even whether it should exist at all. Because of the sensitive nature of its function, Mozilla decided to disable it by default. See bug 1295877, comment 0 for details.
