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 🙏

1、项目搭建

1)项目初始化安装依赖

npm init -y
npm i webpack webpack-cli lodash -D

2)配置webpack

  • 将项目中使用lodash也打包进项目中,增大了项目的体积(不推荐)
// webpack.config.js
const path = require('path')

module.exports = {
  mode: 'development',
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    clean: true,
    filename: 'webpack-numbers.js',
    library: {
      // library 向外暴露的对象名
      name: 'webpackNumbers',
      // 兼容不同的环境 CommonJS、AMD、Node.js 等
      type: 'umd',
    },
  },
}
  • 将lodash等第三方包外部化,由用户安装(推荐)
const path = require('path')

module.exports = {
  mode: 'development',
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    clean: true,
    filename: 'webpack-numbers.js',
    library: {
      // library 向外暴露的对象名
      name: 'webpackNumbers',
      // 兼容不同的环境 CommonJS、AMD、Node.js 等
      type: 'umd',
    },
  },

  // 外部扩展:https://webpack.docschina.org/configuration/externals/#externals
  externals: {
    lodash: {
      commonjs: 'lodash',
      commonjs2: 'lodash',
      amd: 'lodash',
      root: '_',
    },
  },
}

3)配置npm script并打包构建

"build": "webpack --config webpack.config.js"

同时将package.json文件中main设置为打包构建的文件

"main": "dist/webpack-numbers.js",

2、发布流程

1)将npm的registry设置为官方的仓库(我们需要将包发布到官方仓库)

  • 不能发布到taobao,taobao镜像是只读镜像,会发布失败
  • 若要发布的私服,需要将仓库地址设置为私服地址
npm config get registry

// 发布library需要使用官方仓库
npm config set registry https://registry.npmjs.org
npm config set registry https://registry.npm.taobao.org

2)在终端中登录npm

  • npm login输入用户名、密码和邮箱登录npm

3)发布library到npm

  • 使用命令:npm publish
npm logout //登出

// 如果不知道当前登录的账号可以用who命令查看身份:
npm who am i

// 发布的包在72小时内是可以删除的
npm unpublish  <pkg>[@<version>]
npm unpublish [email protected]

3、更新包

  • 1、修改完包的代码后,还需要更新下package.json中的version(不能和之前的版本相同)
  • 2、已经登录过了,只需使用发布命令npm publish更新包

4、发布注意问题

  • 1、必须将registry设置为官方仓库,否则发布失败
  • 2、每次修改后重新发布,需要修改package.json中的版本号

5、测试

  • CommonJS:在test文件夹下创建test.js,可以使用node去运行代码
// test.js
const webpackNumbers = require('../dist/webpack-numbers')

console.log(webpackNumbers.numToWord(3));
  • script 标签测试:在test文件夹下创建index.html
<body>
  <script src="../dist/webpack-numbers.js"></script>
  <script>
    console.log(webpackNumbers);
  </script>
</body>

5、webpack支持es模块引入
