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 🙏

Readme

fis3-hook-babel-imweb

fis3 插件 在parse阶段之后,扫描文件内容,根据某些 es6 特性规则判断文件内容是否使用了 es6 语法 如果判定是,则使用fis3-parser-babel-imweb插件对文件内容进行babel编译 如果判定否,则不做任何事情

Install

npm install fis3-hook-babel-imweb

Usage

add this code to fis.conf

fis.hook('babel-imweb', {
  shutup: true,
  babelOpts: {
    sourceMapRelative: true
  }
});

检测顺序:

  1. file.notHookBabel为真时,直接返回
  2. 不是js类型文件(即!file.isJsLike),直接返回
  3. 文件后缀为.es6.js时,编译
  4. 文件头注释有useES6: true时,编译
  5. 根据参数检测文件内容,符合时,编译

options

  • defaultCheckRegList [Array]: 默认正则检测列表,默认值为
[/useES6:\s*true/, /^\s*(import|const|let|export)\s|=>\s*\{|[^"']`[^`]*\$\{[^`}]+\}[^`]*`|\sclass\s+\w+\s+(extends\s+\w+\s+)?\{/m]

默认检测 es6 语法:const, let, import, export, class, =>, `` 还检测了 useES6: true,可以在文件头注释里面添加这个强制编译

  • checkRegList [Array]: 正则检测列表,需要新增一些检测规则的可以添加这个参数,先检测defaultCheckRegList的正则,再检测这里的
  • defaultCheckFnList [Array]: 和defaultCheckRegList一样,只是这里放的是函数,函数签名: Boolean function(String content),返回是否包含 ES6 语法,目前默认值为[]
  • checkFnList [Array]: checkRegList一样,只是这里放的是函数。
  • shutup [Boolean]: 是否关闭展示编译了哪些文件
  • babelOpts [Object]: fis3-parser-babel-imweb插件使用到的参数,目前只有sourceMapRelative这个参数可以用
