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 🙏

加载压缩文件依赖

npm install

压缩文件

gulp

七个方法

Alt text

使用示例

var file = document.getElementById('demo').files[0];

imageResizeTool.fileResizetoFile(file,0.6,function(res){
    //回调中的res是一个压缩后的Blob类型(可以当做File类型看待)文件;
    console.log(res);
    //做出你要上传的操作;
})

使用Promise

使用过多的会调函数代码看上去会不优雅,如下:

var canvas = imageResizeTool.imagetoCanvas(img);
imageResizeTool.canvasResizetoFile(canvas,quality,file=>{
    imageResizeTool.filetoDataURL(file,data=>{
        imageResizeTool.dataURLtoImage(data,img=>{
            //做相应的操作
        })
    })
})

这时候可以引入 resize.promise.js 文件,以便使用 Promise 进行链式调用,如下:

imageResizeTool.imagetoCanvas(img)
    .then(canvas => imageResizeTool.canvasResizetoFile(canvas,quality))
    .then(file => imageResizeTool.filetoDataURL(file))
    .then(data => imageResizeTool.dataURLtoImage(data))
    .then(img => {
        //做相应的操作
    })
})
