NodeJS 中使用 async/await 等效于 Python 的 time.sleep()

nodejs_sleep_async_example.sh

npm install --save sleep-promise

npm install --save sleep-promise

然后你可以使用

nodejs_sleep_usage.js

const sleep = require('sleep-promise');

// 在任何异步函数中：
await sleep(2000); // 等待 2000 毫秒

const sleep = require('sleep-promise');

// 在任何异步函数中：
await sleep(2000); // 等待 2000 毫秒

完整示例：

nodejs_sleep_full_example.js

const sleep = require('sleep-promise');

(async () => {
    console.log("This prints immediately");
    await sleep(2000);
    console.log("This prints 2 seconds later");
})();

const sleep = require('sleep-promise');

(async () => {
    console.log("This prints immediately");
    await sleep(2000);
    console.log("This prints 2 seconds later");
})();
