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 🙏

babel-plugin-no-debugging

上线前去掉调试代码的Babel插件

安装

npm install -D babel-plugin-no-debugging

使用

.babelrc

{
  plugins: ["no-debugging"]
}

这个插件默认会移除 debugger;console 调用。

这个插件可以移除 debuggerconsolealert 和 自定义的调试函数调用和定义。自定义的debugger函数常常在不好调试的端环境中使用,如在可抓包环境下发起一个简单请求判断代码是否运行到某个位置

注意:据笔者了解 alert 函数调用仍然大量存在于各类管理后台系统中,开启时需要注意。

为保证在开发阶段不转换代码,记得将这个插件只配置在发布阶段:

.babelrc

{
 {
  "env": {
    "publish": {
      "presets": [
        "@babel/preset-env"
      ],
      "plugins": ["no-debugging"]
    }
  }
}

在项目的 package.json 中配置好 scripts 会更加方便:

{
  "scripts": {
    "build": "cross-env BABEL_ENV=publish webpack",
  },
}

options

| Property | Type | Default | Description | | -------- | ------- | ------- | ------------------------------------------------------- | | debugger | Boolean | true | 移除断点调试 debugger; 代码 | | console | Boolean | true | 移除 console 函数调用 | | alert | Boolean | null | 移除 alert 函数调用 | | debugFn | String | null | 移除 指定的自定义调试代码函数(包括调试函数声明和调用) |

例子

使用默认配置:

.babelrc

{
  plugins: [
    [
      "no-debugging"
    ]
  ]
}

转换前:

const a = 12;
const b = 13;

function add(m, n) {
  debugger;
  return m + n;
}

const result = add(a, b);

console.log(result);

转换后:

const a = 12;
const b = 13;

function add(m, n) {
  return m + n;
}

const result = add(a, b);

自定义配置

移除 alert 和 自定义的 debugger 函数

.babelrc

{
  plugins: [
    [
      "no-debugging",
      {
        alert: true,
        debugFn: "requestDebug",
        console: false
      }
    ]
  ]
}

转换前:


const a = 12;
const b = 13;

function requestDebug(name) {
  const debugjs = 'https://example.com/debugger.js'
  request(`${debugjs}?name=${name}`).then(()=>{
    // your code
  })
}

function add(m, n) {
  debugger;
  return m + n;
}

alert(result);

const result = add(a, b);

console.log(result);

requestDebug(result);

转换后:

const a = 12;
const b = 13;


function add(m, n) {
  return m + n;
}


const result = add(a, b);

console.log(result);
