Class: FetchManager

low.FetchManager

Class for managing fetch requests.

Some platforms may bail out if a fetch operation is taking too long, which can easily happen if there are requests waiting for their turn in the network queue.

The FetchManager stores waiting requests in an internal queue to keep the network queue clear of waiting requests in order to prevent certain platforms from bailing out.

It also allows you to abort all pending requests at once on platforms providing the AbortController API.
