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 🙏

A svg compression tool for webpack loader

Readme

用于webpack loader 的svg压缩工具

该包依赖于 svgo

Getting Started

npm i svgo svg-min-loader --save-dev

Basic Usage

webpack

 {
    test: /\.svg$/,
    include: [resolve('packages/SvgIcon/svg')],
    use: [
        {
            loader: 'svg-mini-loader'
        }
    ]
},

也可配合svg-sprite-loader使用,svg-sprite-loader 将我们引用的指定文件夹下的 svg 制作成 svg sprite 并插入 html 的 body 中。

npm i svg-sprite-loader --save-dev

{
   test: /\.svg$/,
   include: [resolve('packages/SvgIcon/svg')],
   use: [
      {
   	loader: 'svg-sprite-loader',
   	options: {
   	   symbolId: 'icon-[name]'
   	}
      },
      {
       loader: 'svg-mini-loader'
      }
   ]
},

svg-min-loader 中在不传参数的时候它默认了一套压缩svg机制,当然可传参进行定制化

{
    test: /\.svg$/,
    include: [resolve('packages/SvgIcon/svg')],
    use: [
	   {
	    loader: 'svg-sprite-loader',
	    options: {
	      symbolId: 'icon-[name]'
	    }
       },
       {
         loader: 'svg-mini-loader',
		 options: {
		   plugins:[
			 {
			  removeViewBox: false
			 }, 
			 {
			  removeUselessStrokeAndFill: false
			 }, 
			 {
			  removeAttrs: {
			     attrs: ['xmlns']
			  }
		     }
		]
	    }
