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 🙏

dataFilter

const handledData = dataFilter(obj, isStrict = false, checkArr = false)

主要是用于处理ajax参数,此处不考虑Symbol,Map,Set,Function等数据类型 isStrict默认为false,过滤掉参数中的null,undefined;当isStrict为true时,会过滤掉空字符串 checkArr默认为false,不会处理数组中的null,undefined,例如[1,undefined,null]这种数据不会做处理;当checkArr为true时,则会进行过滤,此时如果isStrict为true,还会过滤空字符串

merge

const mergedObj = merge(obj1, obj2, obj3)
const mergedArr = merge(arr1, arr2, arr3)

合并多个对象或数组

debounce

防抖函数

throttle

节流函数
