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 🙏

Readme

weapp-qrcode

npm version change-log

ddapp.qrcode.js 在 钉钉小程序 中,快速生成二维码

Usage

先在 wxml 文件中,创建绘制的 canvas,并定义好 width, height, canvasId

<canvas style="width: 200px; height: 200px;" canvas-id="myQrcode"></canvas>

直接引入 js 文件,使用 drawQrcode() 绘制二维码。!!!在 调用 drawQrcode() 方法之前,一定要确保可以获取到 canvas context

在 v0.6.0 版本构建出多个文件,详情移步Build Files说明

// 将 dist 目录下,weapp.qrcode.esm.js 复制到项目目录中
import drawQrcode from '../../utils/weapp.qrcode.esm.js'

drawQrcode({
  width: 200,
  height: 200,
  canvasId: 'myQrcode',
  // ctx: wx.createCanvasContext('myQrcode'),
  text: 'https://github.com/yingye',
  // v1.0.0+版本支持在二维码上绘制图片
  image: {
    imageResource: '../../images/icon.png',
    dx: 70,
    dy: 70,
    dWidth: 60,
    dHeight: 60
  }
})

如果项目使用了 wepy 框架,可直接安装 weapp-qrcode npm包。

npm install ddapp-qrcode --save
import drawQrcode from 'ddapp-qrcode'

drawQrcode({
  width: 200,
  height: 200,
  canvasId: 'myQrcode',
  text: 'https://github.com/yingye'
})

DEMO

更多 demo 可以参考 examples目录,示例包含原生语法及WePY、mpvue、Taro框架。
