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 🙏

类似vuejs 2.x单文件前端框架

框架慢慢完善中,欢迎交流。 支持浏览器版本:ie11,chrome,safari,firefox

安装使用

    npm i -S jtpl
    npm i -S jtpl-loader
    npm i -S jtpl-css-loader

使用说明

  1. 必须通过webpack构建
  2. 需要配置两个loader
    • jtpl-loader,
    • jtpl-css-loader
  3. 跟vuejs 2.x单文件使用类似
  4. 只能存在一个跟元素
  5. 标签必须要闭合
  6. 在文件任何地方需要用到动态数据都使用 {{expression}} 表达式,指令除外
  7. 具体使用可以参考Jtpl-example-project

已经实现的功能

  1. 表达式求值
  2. 嵌套子组件,父子组件传值
  3. 组件css样式隔离,互不污染
  4. 双向数据绑定
  5. 数组操作的监听
  6. 指令,目前实现了j-model,j-show,j-for
  7. 增加数据computed,watch feature
  8. 增加组件slot feature,方便封装通用组件

后续计划实现的功能

  1. 表达式可以使用函数
  2. 数据逐级监听(目前传给子组件的数据当发生变化时候,子组件相应的视图不会更新,只能手动触发子组件的方法更新)
  3. 同级组件数据通信,类似vuex
  4. 路由
  5. mixin,plugin功能,更多指令
  6. 异步加载
  7. 虚拟dom
  8. 单元测试
  9. 改成ts实现
  10. 官网文档

难点心得

  1. 模版解析匹配标签的问题,嵌套解析
  2. 表达式求值的问题
  3. 组件间的css样式污染问题
  4. 双向数据绑定,当里面有嵌套对象和数组的时候,怎么匹配到对应的视图更新
  5. 数据视图的理解划分
  6. 渲染数组,j-for指令,要考虑嵌套for指令监听,求值,难度五颗星^_^

问题

  1. 文件模版里面的js怎么调试,如何把sourceMap映射到这个文件,现在要调试只能把js单独抽出一个文件引入到文件模版中

示例项目

  1. Jtpl-example-project
  2. 线上演示
