You can add them, remove them, +modify them. You can also import an existing zip file or generate one. + +### Getting the object + +#### In a browser + +For a browser, there are two interesting files : `dist/jszip.js` and +`dist/jszip.min.js` (include just one). + +If you use an AMD loader (RequireJS for example) JSZip will register itself : +you just have to put the js file at the right place, or configure the loader +(see [here for RequireJS](http://requirejs.org/docs/api.html#config-paths)). + +Without any loader, JSZip will declare in the global scope a variable named `JSZip`. + +#### In nodejs + +In nodejs, you can `require` it : + +```js +var JSZip = require("jszip"); +``` + +### Basic manipulations + +The first step is to create an instance of JSZip : + +```js +var zip = new JSZip(); +``` + +On this instance, we can add (and update) files and folders with +`.file(name, content)` and `.folder(name)`. +They return the current JSZip instance so you can chain the calls. + +```js +// create a file +zip.file("hello.txt", "Hello[p my)6cxsw2q"); +// oops, cat on keyboard. Fixing ! +zip.file("hello.txt", "Hello World\n"); + +// create a file and a folder +zip.file("nested/hello.txt", "Hello World\n"); +// same as +zip.folder("nested").file("hello.txt", "Hello World\n"); +``` + +With `.folder(name)`, the returned object has a different root : if you add files +on this object, you will put them in the created subfolder. This is just a +view, the added files will also be in the "root" object. + +```js +var photoZip = zip.folder("photos"); +// this call will create photos/README +photoZip.file("README", "a folder with photos"); +``` + +You can access the file content with `.file(name)` and +[its getters]({{site.baseurl}}/documentation/api_zipobject.html) : + +```js +zip.file("hello.txt").asText(); // "Hello World\n" + +if (JSZip.support.uint8array) { + zip.file("hello.txt").asUint8Array(); // Uint8Array { 0=72, 1=101, 2=108, more...} +} +``` + +You can also remove files or folders with `.remove(name)` : + +```js +zip.remove("photos/README"); +zip.remove("photos"); +// same as +zip.remove("photos"); // by removing the folder, you also remove its content. +``` + +### Generate a zip file + +With `.generate(options)` you can generate a zip file (not a real file but its +representation in memory). Check +[this page]({{site.baseurl}}/documentation/howto/write_zip.html) for more +informations on how to write / give the file to the user. + +```js +var content = null; +if (JSZip.support.uint8array) { + content = zip.generate({type : "uint8array"}); +} else { + content = zip.generate({type : "string"}); +} +``` + +### Read a zip file + +With `.load(data)` you can load a zip file. Check +[this page]({{site.baseurl}}/documentation/howto/read_zip.html) to see how to +do properly (it's more tricky that it seems). + +```js +var new_zip = new JSZip(); +// more files ! +new_zip.load(content); + +// you now have every files contained in the loaded zip +new_zip.file("hello.txt").asText(); // "Hello World\n" +``` + |
