# DOM abort

> How Elide supports AbortController and AbortSignal per the DOM Standard, including abort(), any() and timeout(), and signals for fetch, timers and streams.

`AbortController` and `AbortSignal` are globals and follow the [DOM Standard](https://dom.spec.whatwg.org/), including
`AbortSignal.abort()`, `AbortSignal.any()`, `AbortSignal.timeout()`, and the `signal` option of `addEventListener`.
Fetch, timers, and streams accept a signal.

## Example

```js
// abort.mjs
const controller = new AbortController();
controller.signal.addEventListener("abort", () => console.log("aborted:", controller.signal.reason));
controller.abort("user cancelled");

const timeout = AbortSignal.timeout(10);
await new Promise((resolve) => timeout.addEventListener("abort", resolve));
console.log(timeout.reason.name);

const either = AbortSignal.any([new AbortController().signal, AbortSignal.abort("first")]);
console.log(either.aborted, either.reason);
```

`elide run abort.mjs` prints:

```text
aborted: user cancelled
TimeoutError
true first
```
