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 🙏

Build Status

开发本工具的目的是为了规范乐高项目的开发流程、提供统一的项目环境及技术框架,从而提高工作效率。

什么是乐高?

不熟悉的同学,请先看看这个PPT

安装

全局安装:npm install lego-cli -g

脚手架

执行 lego init 命令来搭建环境,会看到如下图:

填写项目名称组件命名空间后,工具就开始自动生成工程了:

注意,组件命名空间是以.lego为后缀的(如 ux.lego),这是项目规范之一。填写时也可以省略后缀,系统会检测并自动加上。

生成完毕,工程的目录结构应该如下:

.
├── Gruntfile.js
├── mock
│   └── config.json
├── node_modules
├── package.json
├── public
│   ├── brix-style
│   ├── index.scss
│   └── ux.lego
├── server.js
└── views
    └── index.vm

其中,我们的组件就放置在 public/ux.lego 目录下。 注意,组件的目录结构必须遵循 [命名空间]/[组件名]/[版本号]。例如,我有一个叫 ceiling 的组件,当前版本为0.1.0,那么它的目录就应该是 public/ux.lego/ceiling/0.1.0/

另外,对于一个乐高组件,它应该由以下的文件组成:

.
├── data.json          //mock数据文件,demo展示用
├── index.js           //组件js模块,继承自brix
├── index.scss         //组件css
├── package.json       //组件描述文件
└── template.vm        //组件vm

开发调试

执行 npm start 启动本地服务。

http服务

http服务通过@逸才mosaic模块提供支持。

监听文件模块由node-dev提供支持,省去了修改配置时重启服务的麻烦。

mock数据

乐高项目的数据文件为mock/*.json,工程初始化时默认提供了一份。JSON对象的格式如下:

{
  //项目数据
  "pageAttribute": {
    "namespace": "ux.lego"
  },
  //项目数据
  "compVersion": {
  },
  //系统数据
  "url": {
    "keyword": "ipad",
    "catid": "",
    "frcatid": "",
    "propertyid": "",
    "refpid": "",
    "refpos": "",
    "gprice": "",
    "clk1": "",
    "loc": "",
    "tag": "",
    "count": 5
  },
  //系统数据
  "env": {
    "serverName": "hotsale4.p4p.cm3",
    "ip": "",
    "url": ""
  },
  //系统数据
  "cookie": {
    "cna": ""
  },
  //组件数据
  "compList": {
  }
}

这是个初始的结构,里面的字段是和开发约定写死的。其中系统数据的字段基本上和跳转串有关,在开发时可以不关注它们。我们需要关注的是 pageAttributecompVersioncompList 这3个字段。其中 pageAttribute 指的是页面配置,目前项目里主要用到的就是命名空间(namespace),在工程初始化的时候会根据你填写的命名空间给它赋好值。compVersion是本页面引用的组件配置,例如:{"ceiling": "0.1.0", "featuredItem": "0.2.0"}。这个配置会输出到页面,brix框架会根据它来统一加载组件的资源(js、css)。

自动化

时至今日,grunt几乎家喻户晓。乐高项目除了用grunt做些打包、压缩的工作外,开发的时候也能帮上忙。利用grunt-contrib-watch这个插件,可以实时监控文件变化,一旦发现目标文件有变化,就执行相应的task。这样做的好处就是,当文件变化时,我们只需要刷新浏览器就可以看到修改后的效果了,更省事了。 工程初始化默认安装了如下插件:

.
├── grunt
├── grunt-contrib-clean
├── grunt-contrib-copy
├── grunt-contrib-cssmin
├── grunt-contrib-sass
├── grunt-contrib-uglify
├── grunt-contrib-watch
└── grunt-lego-upload

添加组件

要添加一个组件,需要执行以下操作:

cd public/xxx.lego
lego add your-component-name/0.x.x

注意,必须在命名空间目录下执行该操作。前面已经提到,组件的路径必须严格遵循[命名空间]/[组件名]/[版本号]。工具会在 path.join(process.cwd(), 'your-component-name', '0.x.x') 这个路径下创建组件。

组件上传

通过lego upload命令上传组件vm文件和组件描述文件

批量上传

通过grunt-lego-upload插件可进行批量上传,点击查看插件配置

执行grunt lego_upload

组件描述文件

组件描述文件是组件目录下的package.json文件,里面包含了对组件的描述(命名空间、组件名、版本等)。

示例:

{
  "author": "xuezu",
  "namespace": "aitaobao.lego",
  "name": "featuredItem",
  "version": "0.3.0",
  "cname": "主区",
  "ename": "featuredItem",
  "keywords": [
    "featuredItem",
    "mainarea",
    "主区"
  ],
  "demo": {}
}

预留的keywordsdemo字段,用于以后的组件查询和demo展示,待讨论。

打包测试

在根目录下执行grunt build,你懂得。
