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 🙏

一个简单的react图片上传组件

Readme

HeadPortrait

前几天项目中使用到头像上传组件万万没想到这么多人下载,看来有很多人需要,就完善下文档吧!其实看我贴的两段代码,也很直白的可以看出,组件很简单,就2个参数

  • 熬夜完成一波优化,原来 piexifjs.load(result) 其中 result可以是 base64 也可以是 BinaryString,但是传入 base64 最终还是会转成 BinaryString,所以在 FileReader 中直接使用 readAsBinaryString 方法获取 二进制文本大大提升了组件性能,现在再大的图片,也都能秒级压缩了,妈妈再也不用担心这个组件的性能问题了

  • side: 图片变长

    • 默认边长 320 jpeg 图片质量 0.32
    • 和 边长 160 图片质量 65 大小差不多,但在手机上显示效果会更好,看不到锯齿
  • onChange: 图片载入完成后的callback函数

    • 其中包括base64格式和blob的二进制格式
    • blob数据可以直接用于formData进行提交
handleHeadChange = (base64, blob) => {
  this.props.dispatch(uploadHead({
    is_save: 1,
    image: blob,
  }))
  this.setState({
    portraitUrl: base64,
  })
}
<HeadPortrait
  side={320}
  className="aClass"
  onChange={this.handleHeadChange} />
