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 🙏

f6 for wx

微信小程序中快速使用 F6 的小工具,帮助用户封装了一些基础的操作,用户也可以参考这里的封装自行处理

基础参数

| 属性名 | 默认值 | 类型 | 是否必传 | 描述 | | --- | --- | --- | --- | --- | | width | 100 | Number | 否 | canvas 的宽度,这个值是页面中组件的宽度 | | height | 100 | Number | 否 | canvas 的高度,这个值是页面中组件的高度 | | pixelRatio | 1 | Number | 否 | 设备像素比,这个字段很关键!!!不传递绘制的图非高清!!!字段来自 getSystemInfo/getSystemInfoSync | | onInit | 空 | Function | 否 | canvas 初始化完成后返回,会携带相关的信息回来,具体看下方表格 | | onTouchEvent | 空 | Function | 否 | 所有的 touch 事件都来源这里,如果需要 f6 处理事件,都需自行传递,未统一处理的原因为,业务方可能需自行定制 | | onError | 空 | Function | 否 | canvas 创建失败的回调 | | style | 空 | String | 否 | 就是简单的 css 样式 |

onInit 函数的回调

| 参数 | 描述 | | --- | --- | | context | canvas 的 context,由组件创建 | | rect | 组件当前所在的位置 | | canvas | native canvas 返回的 element | | renderer | 渲染模式,在小程序下,f6 由两种模式, minimini-native 分别对应 web-canvas 和 native-canvas |

推荐组件

目前存在 2 个组件,一个是 container,另一个是 canvas,container 写法限制性较多,建议使用 canvas,两个组件差别不大,只是事件回传的操作些许区别。

  • canvas(推荐)

canvas 使用 bind:来触发事件,会更容易和原有代码结合

<f6-canvas
  width="{{width}}"
  height="{{height}}"
  forceMini="{{forceMini}}"
  pixelRatio="{{pixelRatio}}"
  bind:onTouchEvent="handleTouch"
  bind:onInit="handleInit"
></f6-canvas>

js 中处理事件

Page({
  data: {
  },
  handleInit(ctx, rect, canvas, renderer) {
  },
  handleTouch(e) {
  },
})
  • container
<f6-canvas
  width="{{width}}"
  height="{{height}}"
  forceMini="{{forceMini}}"
  pixelRatio="{{pixelRatio}}"
  onTouchEvent="{{handleTouch}}"
  onInit="{{handleInit}}"
></f6-canvas>

js 中处理事件, 如果使用 container,只能在 data 中处理逻辑

Page({
  data: {
    ...
    handleInit(ctx, rect, canvas, renderer) {
    },
    handleTouch(e) {
    },
  },
})
