问题 I'm building a transfer files website and I'm facing a big issue ! I'm working with react.js express.js and digital ocean spaces. When I drag the file to the drop zone and hit submit, the file is supposed to be uploaded on digital ocean spaces, it's like amazon s3. So, now I'm able to upload a file without any problem but, it would be much more if I can zip the file on react before sending it to digital ocean via Express. And here is the problem ! I'm not able to send a zipped file ! I have

Zip 压缩、解压技术在 HTML5 浏览器中的应用

JSZip 是一款可以创建、读取、修改 .zip 文件的 javaScript 工具。在 web 应用中,免不了需要从 web 服务器中获取资源,如果可以将所有的资源都合并到一个 .zip 文件中,这时候只需要做一次请求,这样既减少了服务器的压力,同时也可以加快 web 应用的呈现速度。 今天就来探讨下 JSZip 如何与 HT 拓扑 应用结合。先来看看这期 Demo 的效果图: 第一步、需要将应用对相关资源打包成 .zip 文件, 这是我要压缩的文件列表,把响应的资源文件存放到对应的文件夹下,然后在 loadorder 文件中标明资源加载的顺序,loadorder 文件内容如下: 'js/ht.js', 'js/ht-obj.js', 'js/ht-modeling.js', 'obj/equipment.mtl', 'obj/equipment.obj', 'image/equipment.jpg' 在资源加载顺序中,要标明响应资源的相对于 .zip 文件的路径,这样方便在读取 .zip 文件时快速找到相应的资源文件。 第二步、在 html 文件中引入 JSZip 和 JSZipUtils 库,接下来就是请求 .zip 文件,并对 .zip 文件做解析处理。 JSZipUtils.getBinaryContent('res/ImportObj.zip', function

Can't download folder with JSZip

Look at the example from their http://stuk.github.io/jszip/ for example like below : var zip = new JSZip(); // Add a text file with the contents "Hello World\n" zip.file("Hello.txt", "Hello World\n"); // Add a another text file with the
