AbortSignal.timeout() Static Method

Category: DOM
Type: Chromium catches up
Status: Enabled by default (Chrome 103)
Intent stage: Shipped

Summary

Returns a new AbortSignal object that is automatically aborted after a given number of milliseconds. This method can be used by developers to easily implement timeouts for signal-accepting async APIs, e.g. fetch().

Motivation

The main motivating use case for this is helping web developers easily time out async operations, such as fetch(). For example, now you can write: fetch(url, { signal: AbortSignal.timeout(10_000) });
