React

Use tryo in effects with cancellation and retries

Effect with AbortController

import { useEffect, useState } from "react";
import { run } from "tryo";

export function Users() {
  const [users, setUsers] = useState<any[]>([]);
  const [error, setError] = useState<string | null>(null);

  useEffect(() => {
    const controller = new AbortController();
    const signal = controller.signal;

    run(() => fetch("/api/users", { signal }).then((r) => r.json()), {
      retries: 2,
      retryDelay: 300,
      onSuccess: (data) => setUsers(data),
      onError: (e) => setError(e.message),
      ignoreAbort: true,
    });

    return () => controller.abort();
  }, []);

  if (error) return <div>{error}</div>;
  return <pre>{JSON.stringify(users, null, 2)}</pre>;
}
