Pending(Get|Post)Beacon vs PendingBeacon("(Get|Post)", ....

[sefeng211]

Have we considered to shape the API as PendingBeacon("Get", ...) and PendingBeacon("Post", ...)? This would match what the fetch and XHR do. It seems uncommon with the current setup.

It is mainly for easier type safety to make the API shape look like this.

If we made them the same class then we would have to specify that certain methods (like setUrl or setData) will raise exceptions when called on the wrong kind. Making them different classes avoids that and for typescript coders, it becomes a compile-time error to call setUrl of a POST beacon.

The API is now repurposed as fetchLater() which supports both HTTP methods. whatwg/fetch#1647
