Aborting Requests

Browsers will soon support an API to allow developers to abort fetches. Aborting requests within React Request currently is not currently supported, but it is on the project roadmap.

For more, refer to this GitHub issue.

Pseudo-aborts

The <Fetch/> component will "pseudo-abort" requests. With a faux-abort, the actual HTTP request will not be aborted, but there are situations when the response will be ignored:

  1. When the component unmounts
  2. When a new request is initiated while an existing request is already in flight

In these situations, onResponse will be called with an error that has a name equal to AbortError.

Warning: don't use the signal prop

You may be tempted to use the signal prop of <Fetch/> to abort requests, but this may not work as well as you would like it to. The <Fetch/> component will make a new request anytime a new request key is generated from the props that you pass in.

This means that you would need to create a new AbortController any time that there is a new request key. Although this may work for limited use cases, it does not scale well, so we do not recommend it as a general practice.
