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 🙏

hold-back

解决多个异步数据同一个容器渲染混乱的问题。该问题详见: https://hezedu.github.io/hold-back/

Install

npm install hold-back

API

引用

COMMONJS:

var HoldBack = require('hold-back');

./dist文件夹下文件支持AMD加载。直接src的话,会暴露一个全局变量:HoldBack

生成实例

var holdBack = new HoldBack();

holdBack.start(key)

异步流开始时使用.

key Number___或___String, 异步流的唯一标实.

 return Boolean    true 表示当前异步流已存在.    false 表示当前异步流是新创建的.

holdBack.end(key)

异步流结束时使用.跟holdBack.start(key)对应.

key Number___或___String, 异步流的唯一标实.

 return Boolean    true 表示当前异步流是你期望的.    false 表示当前异步流不是你期望的.

示例

var HoldBack = require('hold-back');
var holdBack = new HoldBack();

function asyncLog(key, ms){
  var isAlreadyStart = holdBack.start(key);
  if(isAlreadyStart){
    return; //阻止重复加载.
  }
  setTimeout(() => {
    var isExpect = holdBack.end(key);
    if(isExpect){
      console.log('key', key);
     }
    }, ms);
}
asyncLog('slow', 1000);
asyncLog('fast', 100);

// only log: fast
