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 🙏

Webun

基于webpack5的前端项目打包工具。项目源码:https://github.com/geekip/webun

全局安装,随处使用。项目下无须安装各种编译依赖包,减少众多项目的node_modules占用磁盘空间。 开箱即用零配置,默认开启编译缓存、多线程、代码压缩、代码分割等优化配置,同时也支持自定义配置。 集成bebel swc esbuild,可根据需求自由选择,提升编译速度。 开发调试模式监听文件变更自动刷新浏览器,集成vue react 的HMR热更新。

🛒全局安装

pnpm i webun -g 

💡进入项目

一个项目同时支持react vue共存,能编译jsx tsx ts js + css less sass/scss styl

# 查看使用帮助
webun -h

🐞开发调试

基于webpack-dev-server实现

# 快速调试,默认地址0.0.0.0,默认端口9527
webun
# 指定地址和端口
webun --host 0.0.0.0 --port 8080 
# 调式生产模式,默认无sourceMap
webun --mode production

📦编译打包

# 打包生产模式
webun build
# 打包开发模式,默认有sourceMap
webun build --mode development

🍃忽略缓存

默认开启编译缓存,提升编译速度,但有时修改配置后缓存会造成打包异常,需要忽略缓存进行编译

# 忽略缓存 --force 或 -f
webun --force
webun build -f

📑获取运行时环境变量

模式变量 NODE_ENV 值为:development or production 操作变量 NODE_ACT 值为:serve or build

  • 在配置文件里使用
const isServe = process.env.NODE_ACT === 'serve'
const isDev = process.env.NODE_ENV === 'development'
module.exports = {
  ...
  // 生产环境指定静态文件的地址
  output:{
    publicPath: isDev ? '' : 'http://cdn.com/',
  },
  // 开发环境开启 source-map
  devtool: isDev ? 'eval-cheap-module-source-map' : false,
  // 指定不同的自定义变量
  define:{
    api_base_url: isServe : 'http://localhost/api' : 'http://backend.com/api'
  }
  ...
}
  • 在html模板里使用
<!-- 获取运行时变量 -->
<%= process.env.NODE_ENV %>
  • 在项目文件里使用
// 获取运行时变量
const mode = process.env.NODE_ENV
console.log(mode)
console.log(api_base_url)
