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 🙏

Readme

rem-core

使px单位的css属性自动转化为rem为单位的nodejs 包文件。


- 使用node-css把css解析后,对px为单位对属性进行rem转换处理。
- 对文字进行特殊处理追加至产出的css文件之后。
- developer只用专注开发,配置灵活方便, 对原始文件无侵入。

flexible.js

默认可以配合淘宝的flexible.js使用

调用方式

    rem(content, file, config);

Usage

  • 在css文件第一行声明/* !@norem */ 则整个文件都不做处理(建议用自动化工具控制)
body {
    border-top: 1px;
    border-bottom: 10px;
    padding: 10px; /* @norem */
    background-size: 10px 10px;
}

输出:

body {
    border-top: 1px;
    border-bottom: 0.5557rem;
    padding: 10px;
    background-size: 0.5557rem 0.5557rem;
}

Option

  • rem {Number} 1rem=多少px default 18
  • min {Number} 最小转化值 default 3
  • exclude {Array.<String>} 忽略的样式 default ['width', 'height', 'background', 'background-size']
  • fontSize2Rem: {Boolean} 字体大小是否转rem单位 default true *值为false时会根据dpr输出1倍,2倍,3倍大小的css样式, 这种模式更适合于以内容为主的阅读页面。 *可以根据实际需要写多个不同的配置
  • type {?string} default default 支持flexible
  • dpr {!Number} 1, 2, 3 如设计稿的尺寸为 *320-375 那么dpr为1 *640-720 那么dpr为2

about font-size

  • 对font-size进行了特殊处理,没有使用rem而是根据dpi输出三种大小字体

type: default && fontSize2Rem: false

@media(-webkit-min-device-pixel-ratio: 2) {    
    .course-name {
        font-size: 36px ;
    }
}
@media(-webkit-min-device-pixel-ratio: 3) {
    .course-name {
        font-size: 54px ;
    }
}

type: null && fontSize2Rem: false

[data-dpr="1"] .course-name {
    font-size: 18px; 
}
[data-dpr="2"] .course-name {
    font-size: 36px; 
}
[data-dpr="3"] .course-name {
    font-size: 54px; 
}

关于原始值

-在css未进行压缩模式时可以看到原始值
    margin: 0.6668rem/* @source-size: 25px; */ 0;
