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 🙏

【webpack 打包库和组件】大整数加法打包

Downloads

7

Readme

  • webpack 打包库和组件,npm 发布组件和库

    webpack 除了可以用来打包应用,还可以用来打包 js 库

    实现一个大整数加法库的打包

    • 需要打包压缩版和非压缩版本

    • 支持 AMD/CJS/ESM 模块引入

      要了解 AMD/CJD/ESM/CMD 可以看:

      modules in browsers

    • 支持 ES module

      import * as largeNumber from "large-number";
      largeNumber.add("999", "1");
    • 支持 CJS

      const largeNumber = require("large-number");
      largeNumber.add("999", "1");
    • 支持 AMD

      require(["large-number"], function(largeNumber) {
          largeNumber.add("999", "1");
      });
    • 可以直接通过 script 引入

      <script src="https://unpkg.com/large-number"></script>
      <script>
          largeNumber.add("999", "1");
          window.largeNumber.add("999", "1");
      </script>
    • 如何将库暴露出去?

    sudo npm i webpack webpack-cli -D --unsafe-perm
    sudo npm i terser-webpack-plugin -D
    // webpack配置文件 根目录下:webpack.config.js
    const TerserPlugin=require('terser-webpack-plugin');
    module.exports = {
        mode: "none",
        entry: {
            "large-number": "./src/index.js",
            "large-number.min": "./src/index.js"
        },
        output: {
            filename: "[name].js",
            library: "largeNumber",
            libraryTarget: "umd",
            libraryExport: "default"
        },
        optimization:{
            minimize:true,
            minimizer:{
            new TerserPlugin({
                include:/\.min\.js$/
            })
            }
        }
    };
    //设置入口文件 根目录下:index.js
    if ((process.env.NODE_ENV = "production")) {
        module.exports = require("./dist/large-number.min.js");
    } else {
        module.exports = require("./dist/large-number.js");
    }
    //package.json
    "scripts": {
        "prepublish": "webpack"
    },

    然后添加

    npm publish
