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-function2arrow

一个 Babel 插件,用于将普通函数转换为箭头函数。

功能

  • 将函数声明转换为箭头函数变量声明
  • 将函数表达式转换为箭头函数
  • 保持对象方法和类方法不变
  • 跳过异步函数和生成器函数

安装

npm install babel-function2arrow --save-dev

使用

在你的 .babelrc 文件中添加插件:

{
  "plugins": ["babel-function2arrow"]
}

示例

输入

function add(a, b) {
    return a + b;
}

const multiply = function(a, b) {
    return a * b;
}

输出

const add = (a, b) => {
    return a + b;
};

const multiply = (a, b) => {
    return a * b;
};

注意事项

  1. 不会转换以下类型的函数:

    • 异步函数 (async)
    • 生成器函数 (generator)
    • 对象方法
    • 类方法
  2. 需要注意 this 绑定的变化:

    • 箭头函数不绑定自己的 this
    • 箭头函数继承外层作用域的 this
