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 🙏

需求说明

当我们遇到一个背景色,但是你并不知道这个背景色合适的字体颜色是什么,那么就可以使用这个工具。 具体场景,比如说一个标签背景色是用户自定义的,这个时候就可以使用这个工具,来计算出字体颜色是什么。如果字体颜色写死,则可能导致字体颜色和背景色不一致或接近,导致看不到字体。

支持各种颜色格式,包括rgb、rgba、hsl、hsla、hex、css颜色名,并内置了缓存逻辑。 contrastColor支持传入2个参数,第一个参数为背景色,第二个参数为容器所在背景色(默认为白色),如果你的容器背景色是透明的,则需要传入这个颜色。

使用方法

npm install --save @zhujiegogogo/contrast-color

项目引入

import contrastColor from "@zhujiegogogo/contrast-color"
const color = contrastColor("#000000")
console.log(color)

销毁

import {destroy} from "@zhujiegogogo/contrast-color"
dstroy()
