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 🙏

event-trace

一种无侵入式的打点解决方案

通过事件委托的方式添加打点事件,可以直观管理所有打点事件,摆脱凌乱的侵入式打点

Install

$ npm i event-trace
// or
$ yarn add event-trace

Usage

采用 ES6 语法引入 event-trace

import eventTrace from 'event-trace'

通过 script 标签加载会暴露名为 eventTrace 的全局变量

example

eventTrace('#app', [
    {
        target: '.header',
        handle: () => {
            console.log('click header!')
        },
        delay: 300
    },
    {
        target: '.name',
        handle: (params) => {
            console.log('click name!', params.id)
        },
        params: ['id']
    }
], true)

params

导入的 eventTrace 函数接受三个参数

  • 第一个是需要绑定事件元素元素(可传入css选择器 或 DOM元素的引用)
  • 第二个是配置对象,如下
{
  target: '.header',  // css选择器
  params: ['id']      // 需要的参数(会从dom元素的 dataset 属性中取)
  handle: ({id}) => { // 打点事件处理程序
    console.log(id)   // 如果需要参数需要再params中指定
  },                  // 参数会以对象的形式传入,key为指定的参数名
  delay: 300          // 延时(执行完打点事件后多长时间执行后续事件) ,单位 ms,只在第三个参数为 true 时有效
}
  • 第三个参数布尔变量,为 true 时先执行打点事件,再执行原有逻辑,为 false 时先执行原有逻辑,再执行打点事件
