使用此npm库
https://www.npmjs.com/package/cli-spinners
像这样实现：

const cliSpinners = require('cli-spinners');

console.log(cliSpinners.dots);

您可以在节点中构建自己的微调器，方法是像这样写入stdout：

import { stdout } from "process"

function startSpinner() {
    const characters = ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏']
    const cursorEsc = {
        hide: '\u001B[?25l',
        show: '\u001B[?25h',
    }
    stdout.write(cursorEsc.hide)

    let i = 0;
    const timer = setInterval(function () {
        stdout.write("\r" + characters[i++]);
        i = i >= characters.length ? 0 : i;
    }, 150);

    return () => {
        clearInterval(timer)
        stdout.write("\r")
        stdout.write(cursorEsc.show)
    }
}

然后像这样调用该函数-下面是一个运行4秒然后结束的示例

const stopSpinner = startSpinner();

setTimeout(() => {
    stopSpinner()
    console.log("done")
},4000)
