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 🙏

这是验证码功能的addon。

用法

添加路由

在app.js中

cfg = {}; // 这里可以使用配置addon的一些内容,比如路由的地址。
require('ligle-addon-captcha')(ligle,cfg);// 这步实例化addon,并且保存到ligle.addon上

...

app.use(ligle.addon.captcha.route);//使用addon提供的路由功能

使用中间件

在 xxx.js 中

var checkCode = ligle.addon.captcha.midware.checkCode;
router.get(checkCode,function(req,res){// 验证验证码是否正确。
  ...
});

前端中的添加

表单代码样例

代码截取的一部分:

<form method="post" enctype='multipart/form-data' action="/xxx">
 <input class="ligle-input-md" type="text" name="code" maxlengtd="4" id="code">
 <img class="CAPTCHA" src="/getCode" alt="验证码"/>
</form>

<script>
function onCaptcha(obj){
  var oldsrc = obj.src.split('?')[0];
  obj.src = oldsrc + '?t=' + Math.random(); 
}
$(document).ready(function(){
  $('.CAPTCHA').each(function(i,obj){
    obj.onclick = function(){onCaptcha(obj)};
  });
});
</script>

补充关于addon和plugin

addon和plugin区别:(我自己规定的)

plugin是对引擎的事件有所响应,进行处理,比如打开数据库、程序退出之类的。 (目前就一个global的plugin。提供全局对象的功能。)

addon是对引擎的功能扩展,结合路由、模型、中间件的一个统一体。 (以后我们可能重点就是写addon。)

以上。
