Permissions API
Many of the functionalities that we're translated from mobile to the web require permission from the user.  Think about geolocation, audio/video access (think getUserMedia for camera access), and likewise APIs.  We can probably all agree that requiring permission for access to these APIs is a good thing, but I see a problem:  there's sometimes no way to access each APIs permission level without triggering a request to the user to get that information.  Obtrusive to say the least!


// Get the geolocation status (starts out as "prompt")
// ... meaning the user will be shown an access request if we want it
navigator.permissions.query({ name: 'geolocation' }).then(function(result) {
    /* result.status = "prompt" */
});

// Request geolocation access if we really want it
navigator.geolocation.getCurrentPosition(function(result) { /* ... */  })

// Assuming the user requested access, the permission is now "granted"
navigator.permissions.query({ name: 'geolocation' }).then(function(result) {
    /* result.status = "granted" */
});

// Push notifications require options:
navigator.permissions.query({ name: 'push', userVisibleOnly:true }).then(function(result) { /* ... */ });
