AbortController

{{APIRef("DOM")}} {{AvailableInWorkers}} 

The AbortController interface represents a controller object that allows you to abort one or more Web requests as and when desired.

You can create a new AbortController object using the {{domxref("AbortController.AbortController()", "AbortController()")}}  constructor. Communicating with an asynchronous operation is done using an {{domxref("AbortSignal")}}  object.

Constructor

• {{domxref("AbortController.AbortController()", "AbortController()")}} 
  • : Creates a new AbortController object instance.

Instance properties

• {{domxref("AbortController.signal")}}  {{ReadOnlyInline}} 
  • : Returns an {{domxref("AbortSignal")}}  object instance, which can be used to communicate with, or to abort, an asynchronous operation.

Instance methods

• {{domxref("AbortController.abort()")}} 
  • : Aborts an asynchronous operation before it has completed. This is able to abort fetch requests, consumption of any response bodies, and streams.

Examples

See the AbortSignal page for usage examples.

You can find a full working example on GitHub; you can also see it running live.
