The @azure/abort-controller package provides AbortSignalLike interface and AbortError classes to make it easier to work with the AbortController and the AbortSignal used by fetch built into modern JavaScript platforms.
Customers of Azure SDK for JavaScript in general do not need to use this library. Instead they use AbortController and AbortSignal provided by their platforms and pass the abort signals to Azure SDK operations.
Key links:
Install this library using npm as follows
npm install @azure/abort-controller
Use AbortController to create an AbortSignal which can then be passed to Azure SDK operations to cancel pending work. The AbortSignal can be accessed via the signal property on an instantiated AbortController. An AbortSignal can also be returned directly from a static method, e.g. AbortSignal.timeout(100). that is cancelled after 100 milliseconds.
The below examples assume that doAsyncWork is a function that takes a bag of properties, one of which is of the abort signal.
const controller = new AbortController();
doAsyncWork({ abortSignal: controller.signal });
// at some point later
controller.abort(); Example 2 - Aborting with timeout
const signal = AbortSignal.timeout(1000);
doAsyncWork({ abortSignal: signal });
You can build and run the tests locally by executing rushx test. Explore the test folder to see advanced usage and behavior of the public classes.
