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 🙏

Use

template code

import * as React from 'react';

import Gantt from 'r-gantt-chart'; // 引入组件
import dayjs from 'dayjs'

// 定位函数,根据给定字符串形式的时间生成相对时间轴起点的的偏移值

// `getWidthAbout2Times(start:string,end:string):number`
// 为宽度计算函数,根据给定字符串形式的时间计算两个时间差的宽度值

// `isInRenderingTimeRange(time:string):boolean`
// 判定给定的时间是否在屏幕显示的时间轴范围之内

// startTimeOfRenderArea 屏幕当前显示范围的开始时间的毫秒数

// endTimeOfRenderArea 屏幕当前显示范围的结束时间的毫秒数
