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 🙏

## 初始化项目

Readme

webpack

初始化项目

npm init -y

安装 webpack

全局安装

npm i webpack webpack-cli -g

本地安装

npm i webpack webpack-cli -D

执行本地 webpack

根据刚才全局安装的执行方式,可以猜到本地安装也可以通过命令行路径执行

./node_modules/.bin/webpack

npm@5 引入了 npx 简化了本地 node_modules 的执行

npx webpack
module.exports = {
    mode: 'development',
    mode: 'production'
}

区分开发环境和生产环境

配置文件编程函数

"scripts": {
    "build": "webpack --config webpack.config.js  --mode=development",
    "start": "webpack --config webpack.config.js  --mode=production"
},

entry 入口文件

  • 单 entry
  • 多 entry
// HtmlWebpackPlugin会在打包结束后,自动生成一个html文件,并把打包生成的js自动引入到这个html文件中
const HtmlWebpackPlugin = require('html-webpack-plugin');

new HtmlWebpackPlugin({
    // template: '/index.html'
    template: path.resolve(__dirname, 'src/index.html')
})
