timers

使用 node:timers ↗ API 调度稍后执行的函数。

这包括用于延迟调用函数的 setTimeout ↗、用于重复调用函数的 setInterval ↗，以及用于在事件循环下一次迭代中调用函数的 setImmediate ↗。

index.jsjs

import timers from "node:timers";

export default {
	async fetch() {
		console.log("first");
		const { promise: promise1, resolve: resolve1 } = Promise.withResolvers();
		const { promise: promise2, resolve: resolve2 } = Promise.withResolvers();
		timers.setTimeout(() => {
			console.log("last");
			resolve1();
		}, 10);

		timers.setTimeout(() => {
			console.log("next");
			resolve2();
		});

		await Promise.all([promise1, promise2]);

		return new Response("ok");
	},
};

index.tsts

import timers from "node:timers";

export default {
  async fetch(): Promise<Response> {
    console.log("first");
    const { promise: promise1, resolve: resolve1 } = Promise.withResolvers<void>();
    const { promise: promise2, resolve: resolve2 } = Promise.withResolvers<void>();
    timers.setTimeout(() => {
      console.log("last");
      resolve1();
    }, 10);

    timers.setTimeout(() => {
      console.log("next");
      resolve2();
    });

    await Promise.all([promise1, promise2]);

    return new Response("ok");
  }
} satisfies ExportedHandler<Env>;
