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 🙏

公共方法库(维护项目工具方法)

基于rollup+ts搭建的方法库,抽离常用方法封装,方便在项目中导入使用

如何使用?

  • 在html中直接引入的方式

     <script src="./dist/iri-common-utils.min.js"></script>
  • 在工程项目中引入

1.npm link方式

  1. iri-common-utils工程目录下执行

     npm link
  2. 目标工程目录下执行

     npm install
    
     npm link <utils方法库package包名>
    
     npm run build
    
     npm link
  3. 项目文件中导入相关方法:

     // es6导入
     import {...} from 'utils方法库package包名' 
    
     // 在nodejs中使用
     const {...} = require('utils方法库package包名')

2.npm install方式

  1. 在工程项目主文件夹下执行命令:

     npm i <utils方法库package包名>
  2. 项目文件中导入相关方法:

  // es6导入
  import {...} from 'utils方法库package包名' 

  // 在nodejs中使用
  const {...} = require('utils方法库package包名')
