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 🙏

sprite-tool 自动生成雪碧图和对应图片的scss文件

大部分loader和plugin可以把多张png或者svg打包成一张图片。这样做,图片体积往往会过大,所有页面的图片,都要等待这张被整合后的图片加载完以后才会出现。sprite-tool可以根据你的文件路径分配,帮你生成不同的雪碧图和scss文件。

简述

1.以webpack-spritesmith为基础加工而成
2.自动合成雪碧图
3.支持2x,3x图同时引入,生成两份雪碧图
4.isRetina为true时,图片名字格式例子:example.png(2x) [email protected](3x)
5.开启isRetina时,图片名字需要严格按上述格式,否则无法生成。不开启isRetina时,图片名字不做要求。
6.图片私自转换格式,比如jpg后缀格式修改为png,会导致无法生成雪碧图

npm安装

npm install sprite-tool  --save

使用方式

const spriteTool=require('sprite-tool')
let sprite = new spriteTool({
    iconPath:'src/image',      //目标路径 default:src/image
    targetPath:'src/sprite',  //生成路径 default:src/sprite
    name:'index',            //生成文件名  default:index
    isRetina:false          // 是否开启三倍图模式 default:false
    isRem:true             //是否使用rem
})
sprite.run()

tip:在当前用到sprite的文件里面,引用scss资源,不要在全局一次性引入,保证scss按需引入。
     图片资源只有在被使用到时才会引入,引入scss时不会引入相关图片。
