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 🙏

install

必须安装在全局:npm i -g spritelist

##usage

spritelist

直接扫描当前文件夹的图片文件,打开127.0.0.1:9090地址,生成sprites less样式;

spritelist <path>

扫描定义文件夹下的图片文件:

spritelist -p
  • 加上-n参数,生成的spriten的样式;
  • 加上-p参数,则不生成文件,直接打印在console中;
  • 加上-f参数,则不打印,而是生成sprites less样式的sprites.txt文件;
  • 加上-c--css参数,则生成的是css属性的样式表,需开发者自定义图片路径;

##应用于开发

默认生成的spritelist样式表样例为:

.sprite-1{.sprite-item("1",".jpg",454,810);}
.sprite-2{.sprite-item("2",".jpg",607,810);}
.sprite-3{.sprite-item("3",".jpg",640,854);}

上面的样式表需基于以下的样式:

/** 雪碧图配置 */
.sprite-item(@basename, @ext, @width, @height){
  background-image: url("../img/sprites/@{basename}@{ext}");
  width: @width*1px;
  height: @height*1px;
}

/** 前缀: sprite-。精灵图基本样式与各图层 */
.sprite-ico{display:block; border:none; background-color:transparent; background-repeat:no-repeat;}

开发时,在HTML则非常方便就写出UI级的图标了:

<i class="sprite-ico sprite-1"></i>
<i class="sprite-ico sprite-2"></i>

这样写的好处是:

  1. 把雪碧图抽象出来成为UI级的控件,使用起来极其方便
  2. 把定义雪碧图的样式表抽象出来,方便结合其他雪碧图工具来替换
  3. 保留了雪碧图的原图,添加、修改、删除都方便
