https://github.com/substack/node-mkdirp
https://www.npmjs.com/package/rimraf
==功能==：Like mkdir -p UNIX 命令 rm-rf . nodejs 新建创建文件
var mkdirp = require('mkdirp');
mkdirp('/tmp/foo/bar/baz', function (err) {
if (err) console.error(err)
else console.log('pow!')
});
shelljs
https://www.npmjs.com/package/shelljs
==功能==：hellJS是在Node.js API之上的Unix shell命令的可移植（Windows / Linux / OS X）实现。您可以使用它消除shell脚本对Unix的依赖，同时仍然保留其熟悉而强大的命令。您还可以全局安装它，以便可以从Node项目外部运行它-告别那些讨厌的Bash脚本！
var shell = require('shelljs');
if (!shell.which('git')) {
shell.echo('Sorry, this script requires git');
shell.exit(1);
}
// Copy files to release dir
shell.rm('-rf', 'out/Release');
shell.cp('-R', 'stuff/', 'out/Release');
// Replace macros in each .js file
shell.cd('lib');
shell.ls('*.js').forEach(function (file) {
shell.sed('-i', 'BUILD_VERSION', 'v0.1.2', file);
shell.sed('-i', /^.*REMOVE_THIS_LINE.*$/, '', file);
shell.sed('-i', /.*REPLACE_LINE_WITH_MACRO.*\n/, shell.cat('macro.js'), file);
});
shell.cd('..');
shx
https://www.npmjs.com/package/shx
==功能==：Shx 是一个包装 ShellJS Unix 命令的包装器，为 npm 包脚本中简单的类 Unix 跨平台命令提供了一个简单的解决方案
ShellJS: Good for writing long scripts, all in JS, running via NodeJS (e.g. node myScript.js). shx: Good for writing one-off commands in npm package scripts (e.g. "clean": "shx rm -rf out/").
npm install shx --save-dev
package.json:
{
"scripts": {
"clean": "shx rm -rf build dist && shx echo Done"
}
}
node-ssh
https://github.com/steelbrain/node-ssh###readme
==功能==：Node-SSH 是 ssh2的一个非常轻量级的 Promise 包装器。
chalk
https://github.com/chalk/chalk
==功能==：给终端嵌套您想要的样式。
const chalk = require('chalk');
const log = console.log;
// Combine styled and normal strings
log(chalk.blue('Hello') + ' World' + chalk.red('!'));
// Compose multiple styles using the chainable API
log(chalk.blue.bgRed.bold('Hello world!'));
// Pass in multiple arguments
log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
// Nest styles
log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
// Nest styles of the same type even (color, underline, background)
log(chalk.green(
'I am a green line ' +
chalk.blue.underline.bold('with a blue substring') +
' that becomes green again!'
));
Nzh
https://blog.whyoop.com/nzh/docs/###/
==功能==：适用于需要转换阿拉伯数字与中文数字的场景。特点如下:
以字符串的方式转换，没有超大数及浮点数等问题(请自行对原数据进行四舍五入等操作) 支持科学记数法字符串的转换 支持口语化 支持自定义转换(不论是兆,京还是厘都可以用) 对超大数支持用争议教少的万万亿代替亿亿 当然,你还可以把中文数字再转回阿拉伯数字
npm install nzh --save
var Nzh = require("nzh");
var nzhcn = require("nzh/cn"); //直接使用简体中文
var nzhhk = require("nzh/hk"); //繁体中文
var nzhcn = Nzh.cn; // 使用简体中文, 另外有 Nzh.hk -- 繁体中文
nzhcn.encodeS(100111); // 转中文小写 >> 十万零一百一十一
nzhcn.encodeB(100111); // 转中文大写 >> 壹拾万零壹佰壹拾壹
nzhcn.encodeS("1.23456789e+21"); // 科学记数法字符串 >> 十二万三千四百五十六万万七千八百九十万亿
nzhcn.toMoney("100111.11"); // 转中文金额 >> 人民币壹拾万零壹佰壹拾壹元壹角壹分

p-queue
https://github.com/sindresorhus/p-queue###readme
==功能==：对限制速率的异步（或同步）操作很有用。例如，在与REST API交互时或在执行CPU /内存密集型任务时。
const {default: PQueue} = require('p-queue');
const got = require('got');
const queue = new PQueue({concurrency: 1});
(async () => {
await queue.add(() => got('https://sindresorhus.com'));
console.log('Done: sindresorhus.com');
})();
(async () => {
await queue.add(() => got('https://avajs.dev'));
console.log('Done: avajs.dev');
})();
(async () => {
const task = await getUnicornTask();
await queue.add(task);
console.log('Done: Unicorn task');
})();
sleep
https://www.npmjs.com/package/sleep
==功能==：sleep
npm i sleep
var sleep = require('sleep');
function msleep(n) {
Atomics.wait(new Int32Array(new SharedArrayBuffer(4)), 0, 0, n);
}
function sleep(n) {
msleep(n*1000);
}
delay
https://github.com/sindresorhus/delay###readme
==功能==：将承诺推迟一定的时间
npm install delay
const delay = require('delay');
(async () => {
bar();

// Executed 100 milliseconds later
baz();
})();
better-scroll
