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 🙏

Hu-CLI 是一个基于 rollup 的打包工具

安装

  > npm install @moomfe/hu-cli

指令

  // 打包构建指令, 会自动对代码进行压缩处理
  > hu build

  // 监听模式
  > hu watch

配置

  // hu.config.js
  //  - 此配置表为默认配置
  module.exports = {

    // 打包模式
    //  - 开发环境: 'development' || false
    //  - 生产环境: 'production' || true
    //     - 生产环境会自动调用代码压缩工具对代码进行压缩, 速度较慢
    mode: 'development',

    // 打包入口文件
    input: 'index.js',
    // 打包输出文件
    output: 'index.js',

    // 打包入口目录
    inputDir: './src',
    // 打包输出目录
    outputDir: './dist',

    // 输出的文件类型 ( amd, cjs, system, esm, iife, umd )
    format: 'iife',
    // 生成 UMD 和 IIFE 模块的名字
    name: '',

    // 在打包好的文件最顶部插入一段内容
    banner: '',

    // 将代码中指定文本进行替换 ( 对象形式 )
    replace: {
      // 'process.env.NODE_ENV': JSON.stringify('production')
    },
    // 将代码中指定文本进行替换 ( 数组形式 )
    //  - 支持传入正则
    replace: [
      // { from: 'process.env.NODE_ENV', to: JSON.stringify('production') },
      // { from: /aaa(?=-)/, to: 'AAA' }
    ],
    
    // 将代码中指定文本进行替换 - 在写入文件前进行替换
    // 规则与 "replace" 相同
    bundleReplace: {},

    // 外部依赖
    //  - 用于定义项目中的外部依赖
