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 🙏

组件结构

//设置文本全局样式
setTextDefaultStyle({
  fill: '#fff'
})

function template() {
    //模板参数:#child1 @click=onClick $prop1=string x=number
    //# 组件id,对应同名成员变量,会赋值到组件显示对象的name属性上
    //#slot,在自定义组件中指定子显示对象作为插槽
    //@ 事件,事件处理函数的this绑定组件实例
    //$ 传给子组件的属性,子组件通过this.$.a获取,传入的值解析为字符串
    //不带前缀的表示直接设置显示对象的属性,自定义组件将设置view的属性,值类型是数字,一般用于设置x,y
    //ObservablePoint类型属性可直接赋值,例如anchor=0.5设置anchor.x和anchor.y均为0.5
    //也可以单独设置anchor.x=0.5
    //注意所有属性值都不能带空格
    return [
        Child1("#child1 @click=onClick $prop1=dd width=10 x=0"),
        OContainer([
            Child("#c1"),
            OContainer("#slot"),
            Child("#c3 $label=标题")
        ]),
        OText("Oixi Demo", "#title", style),
        OSprite("texture.png", "#aaa", [])
    ]
}

class ComponentClass extends AbstractComponent implements IRoute {
    $: {label:string} //从父容器传过来的
    child1: Child = null
    container:Sprite = null
    title:Text = null //内部组件继承pixi对象,没有view属性

    constructor() {
      //使用Sprite做自定义组件视图容器
      super(true)
    }

    onClick() {
        //事件可以使用pixi的EventEmitter
        this.emit('change')
    }

    //以下是Component的方法
    get view() {
        //返回这个组件的根容器DisplayObject
    }

    created(){
        //根据数据添加子显示对象列表可以在这里写
        let itemArray = [{text:'t1'}]
        itemArray.forEach(m =>{
            this.container.addChild(new Text(m.text))
        })

        //适配布局,相对于画布,要保证父容器和舞台同宽高
        layout(child1).top(0).left(0).center(0)
    }

    //以下是IRoute的方法
    actived() {}

    reactived() {}

    deactived() {}
}

export function Component(attributes, slots) {
    return buildComponent(new ComponentClass, attributes, slots, template)
}
