## README

JSZip
=====

A library for creating, reading and editing .zip files with JavaScript, with a
lovely and simple API.

See https://stuk.github.io/jszip for all the documentation.

```javascript
const zip = new JSZip();

zip.file("Hello.txt", "Hello World\n");

const img = zip.folder("images");
img.file("smile.gif", imgData, {base64: true});

zip.generateAsync({type:"blob"}).then(function(content) {
    // see FileSaver.js
    saveAs(content, "example.zip");
});

/*
Results in a zip containing
Hello.txt
images/
    smile.gif
*/
```
