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 🙏

    export default class Index extends wepy.page {
        data={
            clipParams:{
                    src:'', //字符串, 图片path 必填
                    mode:"rectangle", //选填,默认rectangle
                    /* 两种模式
                    通过的mode设定
                    mode:'rectangle' 返回图片
                    mode:'quadrangle' 并不返回图片,只返回在图片中的四个点,用于perspective correction(可以查找OpenCV相关资料)
                    */
                    sizeType:["compressed"],//数组,选填 ['original', 'compressed'], 默认original

        onLoad(){
            let chooseImage=new Promise((resolve,reject)=>{
                wx.chooseImage({
                    count: 1, // 默认9
                    sizeType: ['original', 'compressed'], // 可以指定是原图还是压缩图,默认二者都有
                    sourceType: ['album', 'camera'], // 可以指定来源是相册还是相机,默认二者都有
                    success(res) {
                        resolve(res.tempFilePaths[0]);
                    }
                })
            })
            chooseImage.then((path)=>{
                this.clipParams.src=path;
                this.clipParams.visable=true;
                this.$apply();
            })
        }
        
        events = {
              //裁剪完的图片
              wepyCropperFinsh(path){
                
              }
            };  // 声明组件之间的事件处理函数
    }
