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 🙏

GULP CSS Sprite

gulp-spriter(gulp css自动合并雪碧图)

来源:https://github.com/roninliu/gulp-spriter

转载修复

.pipe(spriter({
    sprite: "test.png",
    slice: "./src/slice",
    outpath: "./src/images/slice",
    imgPathFromCss: "../images", //新增
    isH5: true  //新增
  }))

imgPathFromCss: "../images"

增加了 生成CSS文件中雪碧图的路径可选择 的功能。 路径为 雪碧合成图导出文件夹相对于css文件的路径。

imgPathFromCss: "isH5"

判断是否是H5,若是,则将雪碧图的背景定位都除以2.(为了配合公司业务移动端原图是实际需要的2倍问题)

一般人使用isH5不填就好。 examples文件下中的实例是之前作者留下的。

简介

gulp-spriter:帮助前端工程师将css代码中的切片图片合并成雪碧图,支持retina图片。

功能

  • 使用二叉树排列算法,对图片排序优化
  • 自动收集css中带切片的图片(仅对background-image:url("slice/xx.png")有效)
  • 自动在原来的css中添加background-position属性
  • 支持生成适用于高清设备的雪碧图,并在css文件追加媒体查询css代码

依赖

gulp-spriter使用spritesmith作为图片生成的基础算法

安装

npm install gulp-spriter-ny

配置

导入gulp-spriter依赖:

var spriter = require("gulp-spriter-ny");

gulpfile配置文件中增加task,如下:

gulp.task("css",["clean"],function(){
  return gulp.src("./src/css/xxx.css")
         .pipe(spriter({
            sprite:"test.png",
            slice:"./src/slice",
            outpath:"./build/tests"
          }))
         .pipe(gulp.dest('./build/css'))
})
