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 🙏

css3 support

Readme

提供一些工具方法以便处理与css3相关兼容性的问题。

下载:

> npm install css3support

使用

import { type, camelCase, getCssPrefix } from 'css3support';

具体提供的方法如下。

type

判断值的具体类型。

import { type } from 'css3support';

function fn() {}
let reg = /^123[a-z]{0, 10}/g;

console.log(type(0));   // number
console.log(type(false));  // boolean
console.log(type('hello')); // string
console.log(type(null));  // null
console.log(type(type.a)); // undefined
console.log(type(NaN));   // number
console.log(type([1, 2])); // array
console.log(type({name: 'bo'})); // object
console.log(type(fn));  // function
console.log(type(reg));  // regexp
console.log(type(new Date()));  // date
console.log(type(new Error()));  // error

camelCase

将css属性兼容性写法,转化为对应的js特性值。

import { camelCase } from 'css3support';

console.log(camelCase('-webkit-animation'));  // WebkitAnimation
console.log(camelCase('-moz-animation')); // MozAnimation
console.log(camelCase('-o-animation')); // OAnimation
console.log(camelCase('-ms-animation')); // msAnimation

toFirstUpperCase

字符串首字母转化为大写

import { toFirstUpperCase } from 'css3support';

console.log(toFirstUpperCase('hello')); // Hello

getCssPrefix

获取浏览器支持的css3前缀。如果浏览器版本比较新,对css3属性直接支持,则返回空字符串。可以通过传入特定的css属性来判断该属性的兼容性,如果为未传入,则根据transform来判断。

import { getCssPrefix } from 'css3support';

console.log(getCssPrefix());   // '' || -webkit- || -moz- || -o- || -ms-
getCssPrefix('transition'); 

getCapitalPrefix

获取浏览器支持的css3特性值前缀。主要针对transitionend, animationend等事件兼容性写法,与属性特性值略有不同。

import { getCapitalPrefix } from 'css3support';

console.log(getCapitalPrefix()); // ['', 'webkit', 'moz', 'o', 'MS']; 取其一

getAttrName

得到浏览器支持的对应css属性的特性值。

import { getAttrName } from 'css3support';
getAttrName('transition');  // WebkitTransition

getEventName

获取浏览器支持的事件名,包括 animationstart, animationcancel, animationend, transitionend 等常用动画事件。

import { getEventName } from 'css3support';
getEventName('animationend'); // MSAnimationend

animationFrame

requestAnimationFrame 与 setTimeout 兼容性方法支持

cancelFrame

cancelAnimationFrame 与 clearTimeout 兼容性方法支持

getStyle

获取元素属性值

getStyle(elem, 'height');  // 100px

setStyle

设置元素属性值

 setStyle(elem, {
   height: '100px'
 })
