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 🙏

Chrome扩展构建插件 rollup-plugin-crx

猎豹浏览器扩展集合

Chrome扩展构建插件(rollup-plugin),将之前散文件开发的扩展项目接入工程化管理开发。

本插件提供以下功能:

  1. 扩展开发支持热重载
  2. 合并构建多个扩展项目

目录

项目背景

rollup-plugin-crx,让浏览器扩展项目实现工程化。

以前的扩展项目是通过散文件的形式开发,项目松散,难以管理。而且开发调试繁琐,需要手动重新加载扩展项目。

安装依赖

项目通过 monorepo 形式管理代码,依赖安装管理通过 lerna,在 liebao_extensions 目录执行以下命令:

npm install

使用说明

// rollup-config.js
export default crxPlugin({
  isModule: env !== "developement",
  extensionId,
  name: "extension name",
  version: "1.0.0",
  port: 3080,
  publicDir: pathResolve("src/images"),
  background: [
    pathResolve("src/background/index.ts")
  ],
  content: [
    {
      matches: ["<all_urls>"],
      js: [pathResolve("src/content/setup.ts")],
    }
  ],
  permissions: [
    "tabs"
  ],
  plugins: [
    replace({
      'process.env.NODE_ENV': JSON.stringify(env),
      preventAssignment: false
    }),
    nodeResolve(),
    commonjs(),
    esbuild()
  ],
});

构建生产

npm run build

项目结构

src              
├─ index.ts      
├─ merge.ts      // 合并扩展构建逻辑
├─ process.ts    // 进程相关逻辑
├─ reload.ts     // 热重载
├─ type.ts       // 工程类型声明
├─ utils.ts      // 构建工具函数
└─ ws.ts         // web socket

注意事项

  1. 构建处理后的background只会是background.html(background只有这样才能实现esm)。
  2. content-script实现esm的方式是import(),所以入口setup必须是一个只执行的异步函数。
  3. 图片文件夹还没实现监听变动,在dev过程中修改图片资源需要重新执行构建。
  4. __images会被替换为项目目录下src/images的路径
