Abort Handling

Cancellation with AbortSignal and abort error handling

Recommended pattern

import { run } from "tryo";

const controller = new AbortController();
const r = await run(() => fetch("/api", { signal: controller.signal }), {
  ignoreAbort: true,
  onAbort: (s) => console.log("abort"),
});
controller.abort();

With ignoreAbort: true, aborts do not trigger onError and return an error result with code ABORTED.

In React

useEffect(() => {
  const c = new AbortController();
  run(() => fetch("/api", { signal: c.signal }), { ignoreAbort: true });
  return () => c.abort();
}, []);
