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 🙏

Readme

流程:

1. 注册一个npm账号

2. 创建一包文件夹(名字自己取,不要和NPM上已有的包名重复冲突就好)

3. npm int

4. 创建index.js README.md

5. npm adduser (使用终端命令行 如果是第一次发布包,执行以下命令,然后输入前面注册好的NPM账号,密码和邮箱,将提示创建成功)

6.npm login (如果不是第一次发布包,执行以下命令进行登录,同样输入NPM账号,密码和邮箱)

7.注意:npm adduser成功的时候默认你已经登陆了,所以不需要再进行npm login了

npm publish(进入项目文件夹下 发布包)

npm ERR publish 403

You do not have permission to publish 'bootstrap'.Are you logged in as the corrent user?:bootstrap (npm 已经有此包)

myMacBook-Pro:sugars_demo sugars$ npm publish

更新已经发布的包

更新包的操作和发布包的操作其实是一样的

npm publish

但要注意的是,每次更新时,必须修改版本号后才能更新,比如将1.0.0修改为1.0.1后就能进行更新发布了。 这里的包版本号有一套规则,采用的是semver(语义化版本),通俗点意思就是版本号:大改.中改.小改

usage

npm install jswaterfall --save
window.onload = function() {
  const waterfall = new Waterfall({
    number: 20,                 // 一次性加载的图片个数;必填
    // fixWidth: 1250,          // 容器 width: 选填:填上后会使 window.resize 失效,fixWidth 属性优先级大于 width 属性
    // width: 1250,             // 容器 width;选填: 默认为浏览器的宽度,(后期考虑可以设置为某个节点的宽度)
    // container: 'waterfall',  // 容器 id;选填:默认为 'waterfall'
    // scrollElem: 'content',   // 绑定 scroll 的节点 id,默认为 window
  })

  waterfall.on("load", function () {
    // 模拟 ajax 异步添加图片
    setTimeout(function () {
      const $waterfall = document.getElementById('waterfall')
      for (let i = 0; i < 20; i++) {
        const img = document.createElement('img')
        img.setAttribute('src', `images/${i + 1}.png`)
        img.setAttribute('class', 'waterfall-box')
        $waterfall.appendChild(img)
      }
      waterfall.done() // 同步/异步写法都要加上这句,通知加载完成
    }, 1000)
  })
}
