Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

基于Node.js的构建工具

安装

$ npm install -g lei-run

使用

在当前目录新建文件tasks.run.js

// 注册任务test
register('test', function () {

  // 执行命令
  exec(`eslint . --fix`);
  // 通过$ret获取上一个命令返回的结束代码,默认为0
  print($ret);

  // 顺序执行多条命令,详当于 cmd1 && cmd2 && cmd3
  mexec([
    'ls .',
    'cat README.md',
  ]);

  // 可通过argv得到启动参数数组
  // 通过env得到环境变量对象
  // 另外启动参数也可以同$N获得(N是0到9的数字)
  print($5);

  // 可以通过clc获取cli-color模块,用于输出带颜色的文字
  print(clc.green(`hello, world`));

  // 结束程序并返回指定代码
  // exit(3);

  // 另外可以执行任意Node.js代码
  // 比如require('xxx')载入其他模块

  // 以下内置模块已自动载入,直接使用模块名即可:fs、os、path、assert
  // 比如print(os.cpus());

});

// 注册任务test2
register('test2', function () {

  // 打印出所有参数
  for (const v of argv) {
    print(v);
  }

});

// 注册任务all
register('all', function () {

  // 分别之前以上两个任务
  run('test');
  run('test2');

});

然后可以通过以下命令执行任务test

$ run test

如果当前目录没有tasks.run.js文件,也可执行以下命令自动生成一个初始的文件:

$ run --init

以模块的方式使用

新建任务文件task.js

'use strict';

// 载入模块
require('lei-run');

// 以下使用方法不变
register('test', function () {
  print(color.yellow('hello, world'));
});

执行任务:

$ node task.js test

全局模块

  • fs - https://nodejs.org/api/fs.html
  • path - https://nodejs.org/api/path.html
  • assert - https://nodejs.org/api/assert.html
  • os - https://nodejs.org/api/os.html
  • shell - https://www.npmjs.com/package/shelljs
  • rd - https://www.npmjs.com/package/rd
  • color - https://www.npmjs.com/package/cli-color
  • utils - https://www.npmjs.com/package/lei-utils

可直接使用,比如:

console.log(os.cpus());

注册任务

  • register(name, handler) - 注册任务
  • run(name) - 执行任务
  • target - 构建目标

全局函数

  • exec(cmd[, opts]) - 以同步方式执行命令,并自动打印结果,返回命令的结束代码(成功为0
  • mexec(cmds[, opts]) - 使用exec()依次执行多条命令,如果有命令返回的代码不为0则返回
  • aexec(cmd[, opts]) - 异步方式执行命令,并自动打印结果
  • print(msg) - 打印内容到控制台
  • onExit(fn) - 当进程退出时执行
  • exit([code, msg]) - 退出进程

全局变量

  • env - 环境变量
  • argv - 启动参数
  • $0 ~ $9 - 第09个启动参数
  • $ret - 上一条使用exec()执行的命令的返回代码
  • pwd - 当前工作目录,如果改变改变量的值也会改变当前工作目录
  • uptime - 进程已启动的时间(秒)
