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 🙏

F2 微信小程序

F2 的微信小程序版本,支持原生 F2 的所有功能,欢迎使用反馈。

快速体验

  • 微信扫码体验

  • 使用微信开发者工具打开此项

说明

为了方便使用,我们封装了微信小程序的自定义组件,故需要微信小程序支持使用 npm 安装第三包。重要:版本要求

  1. 小程序基础库版本 2.7.0 或以上
  2. 开发者工具 1.02.1808300 或以上开始,小程序支持使用 npm 安装第三方包。

如何使用

1. 安装依赖

项目默认初始化出来的是没有package.json的,需要新增package.json后再安装

## 没有package.json时执行下面这段
## echo "{}" > package.json

npm install @antv/wx-f2 --save

安装好依赖包之后,点击工具顶部菜单栏的详情:

勾选“使用 npm 模块”选项:

最后点击开发者工具中的菜单栏:工具 --> 构建 npm 即可运行。

如果碰到 @babel/runtime 未找到npm包入口文件,直接忽略就行了,不影响使用(强迫症碍眼的话,手动删除node_modules/@babel/runtime目录)

rm -rf node_modules/@babel/runtime

2. 使用自定义组件

1. 打开json文件,引入组件

{
  "usingComponents": {
    "f2": "@antv/wx-f2"
  }
}

2. wxml 使用组件

 <f2 class="f2" data="{{data}}" bind:draw="draw" />

3. wxss 设置宽高

.f2 {
  width: 100%;
  height: 500rpx;
}

4. 实例化图表

Page({
  data: {
    data:[
      { value: 123, type: '运行指数', date: '10/01' },
      { value: 62, type: '历史均值', date: '10/01' },
      { value: 212, type: '运行指数', date: '10/02' },
      { value: 59, type: '历史均值', date: '10/02' },
      { value: 53, type: '运行指数', date: '10/03' },
      { value: 210, type: '历史均值', date: '10/03' },
      { value: 162, type: '运行指数', date: '10/04' },
      { value: 1, type: '历史均值', date: '10/04' }
    ]
  },
  draw ({ detail: { chart, data } }) {
    chart.source(data, {
      date: {
        range: [0.05, 0.95]
      }
    })
    chart.legend('type', {
      align: 'right',
      itemWidth: 80
    })
    chart.line().shape('smooth').position('date*value').color('type', ['#de5341', '#4a81ed'])
    chart.area().shape('smooth').position('date*value')
      .color('type', ['l(90) 0:#de5341 1:#ffffff', 'l(90) 0:#4a81ed 1:#ffffff'])

    // 无需render
  }
});
