How can you use the AbortController API in fetch requests?

Explain how the AbortController API works in conjunction with the Fetch API to manage or cancel requests.

#fetch#api#abortcontroller

Answer

  1. Create an instance of AbortController.
  2. Pass the controller's signal to the fetch request.
  3. Call controller.abort() to cancel the request if needed.
  4. Handle the abort in the fetch promise's catch block.

Trade-offs:

  • Allows for cancellation of ongoing requests, improving user experience.
  • Extra code complexity for implementing cancellation logic.
