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 🙏

jr8前端工程化整体解决方案

jr8是58金融事业部在百度fis2和jello的基础上封装改造而来,用以和后端Java配合的整体解决方案

流程设计

step1 step2 step2-2 step2-3 step3 step3-2 step4 step5 step5-2 step5-3 step6

##使用jr8有如下限制:

  • 后端为Java
  • 前后端分离,前端负责制定页面样式,后端负责填充页面数据
  • 后端Java使用velocity模板
  • nodejs版本为v4及以下

##jr8基础功能

  • 各种编译器转换,ES6、coffee、markd、_.template、jade、react、less、sass、scss...
  • 校验jshint、csslint...
  • 资源优化、压缩:uglifyjs、cleancss...
  • 图片sprite、图片压缩、base64等常用前端优化手段
  • md5戳
  • amd定义包装
  • css类化(js加载)

##jr8核心功能

  • 一键发布、实时监听并更新资源到tomcat jr8 release -cwL

  • 模拟vm数据及ajax异步数据

彻底分离前后端,从此FEer自行调试vm及其变量,再也不用等后端渲染数据。 FE模拟vm路径及vm变量和ajax返回值变得及其简单 rewrite ^\/login$ /page/login/login.vm 代表http://localhost/login 请求被分发到login.vm渲染 login.json: {username: "张三", password: "123456"} 表示用json数据 mock vm变量:username和password的具体值 ajax返回值mock方法同上

  • 资源定位

分离开发路径与部署路径,完美支持html、js、css中的任意资源定位。

  • 还在写gulp、grunt过滤流操作吗?
  • 还在为各种奇怪的定位关键字命名发愁吗?
  • 内容嵌入
  • html里嵌入html、js、css、base64
  • js里嵌入template、js、css、base64
  • css里嵌入css、base64
  • 依赖声明 - 产出资源文件列表
  • html依赖html、js、css
  • js依赖js、css
  • css依赖css
  • 自动加载所有依赖文件(CSS合并&前置 | JS后置)
  • 假设login页面引用了slider.js和form.js,而form.js又依赖validate.js、button.js和modal.js
  • 每一个js文件可能有对应的css文件,也可能没有
  • 某天form.js不需要依赖button.js了,这么多页面,button.css怎么删?
  • login页面的开发者需要手动维护这么多js和css引用吗?
  • 业务页面无需引入业务JS、CSS文件,jr8框架自动加载依赖并优化合并页面所需资源。开发人员再也不用担心性能优化的问题了

  • 页面打点统计(一个参数搞定:trace)

    jr8 release -cw trace

  • 页面越来越多,测试时找到对应的url地址越来越麻烦,浏览器里还得手动输入url?

自动生成黄页,列出所有页面路径

##安装jr8

  • 安装nodejs

推荐安装node-v4 v0.12及以下不支持node-sass;v6不支持的更多

  • 安装jr8: npm install -g jr8

如果网速慢的话也可以使用国内npm代理安装jr8: npm --registry http://registry.cnpmjs.org install -g jr8
