Quick Start

import { createMemoryQueue } from "@suaveplan/queue/queue/memory-queue";
import { runWorker } from "@suaveplan/queue/worker/queue-worker";

const queue = createMemoryQueue<{ userId: string }>();
await queue.enqueue({ userId: "user_1" });
await queue.enqueue({ userId: "user_2" });

const stats = await runWorker(queue, async (job) => {
  console.log("Processing user:", job.payload.userId);
}, {
  concurrency: 2,
  retryPolicy: { maxAttempts: 3, backoffMs: 1000, backoffMultiplier: 2 },
});
console.log(stats); // { processed: 2, succeeded: 2, failed: 0, dead: 0, retried: 0 }
