+title: "How to read a file"
+layout: default
+section: example
+---
+
+This page explains how to read an existing zip file or add a existing file into
+the zip file.
+
+
+### In the browser
+
+#### AJAX request
+
+Getting binary data with an ajax request is hard (mainly because of IE <= 9).
+The easy way is to use [JSZipUtils.getBinaryContent](https://github.com/stuk/jszip-utils).
+With JSZipUtils.getBinaryContent, you can do the following (see the
+documentation for more examples) :
+
+```js
+JSZipUtils.getBinaryContent('path/to/content.zip', function(err, data) {
+  if(err) {
+    throw err; // or handle err
+  }
+
+  var zip = new JSZip(data);
+});
+```
+
+<br>
+
+If you need to adapt an existing solution to what getBinaryContent does, here
+are the details. When doing a XHR request (level 1, without setting the
+`responseType`) the browser will try to interpret the response as a string and
+decode it from its charset. To avoid this on Firefox/Chrome/Opera, you need to
+set mime type : `xhr.overrideMimeType("text/plain; charset=x-user-defined");`.
+On IE <= 9, this is harder. The overrideMimeType trick doesn't work so we need
+to use [vbscript](http://stackoverflow.com/questions/1095102/how-do-i-load-binary-image-data-using-javascript-and-xmlhttprequest)
+and non standard attributes.
+On IE > 9, overrideMimeType doesn't work but xhr2 does.
+
+With [xhr 2](http://caniuse.com/xhr2), you can just set the responseType
+attribute : `xhr.responseType = "arraybuffer";`. With this, the browser will
+return an ArrayBuffer.
+
+#### Local files
+
+If the browser supports the [FileReader API](http://caniuse.com/filereader),
+you can use it to read a zip file. JSZip can read ArrayBuffer, so you can use
+`FileReader.readAsArrayBuffer(Blob)`, see this [example]({{site.baseurl}}/documentation/examples/read-local-file-api.html).
+
+### In nodejs
+
+JSZip can read Buffers so you can do the following :
+
+#### Local file
+
+```js
+"use strict";
+
+var fs = require("fs");
+var JSZip = require("jszip");
+
+// read a zip file
+fs.readFile("test.zip", function(err, data) {
+  if (err) throw err;
+  var zip = new JSZip(data);
+});
+
+// read a file and add it to a zip
+fs.readFile("picture.png", function(err, data) {
+  if (err) throw err;
+  var zip = new JSZip();
+  zip.file("picture.png", data);
+});
+```
+
+#### Remote file
+
+There are a lot of nodejs libraries doing http requests, from the built-in
+[http](http://nodejs.org/docs/latest/api/http.html) to the
+[npm packages](https://www.npmjs.org/browse/keyword/http). Here are two
+examples, one with the default http API, the other with
+[request](https://github.com/mikeal/request) (but you're free to use your
+favorite library !). If possible, download the file as a Buffer (you will get
+better performances). If it's not possible, you can fallback to a binary string
+(the option is likely to be `encoding : "binary"`).
+
+##### With http :
+
+```js
+"use strict";
+
+var http = require("http");
+var url = require("url");
+var JSZip = require("jszip");
+
+var req = http.get(url.parse("http://localhost/.../file.zip"), function (res) {
+  if (res.statusCode !== 200) {
+    console.log(res.statusCode);
+    // handle error
+    return;
+  }
+  var data = [], dataLen = 0;
+
+  // don't set the encoding, it will break everything !
+  // or, if you must, set it to null. In that case the chunk will be a string.
+
+  res.on("data", function (chunk) {
+    data.push(chunk);
+    dataLen += chunk.length;
+  });
+
+  res.on("end", function () {
+    var buf = new Buffer(dataLen);
+    for (var i=0,len=data.length,pos=0; i<len; i++) {
+      data[i].copy(buf, pos);
+      pos += data[i].length;
+    }
+
+    // here we go !
+    var zip = new JSZip(buf);
+    console.log(zip.file("content.txt").asText());
+  });
+});
+
+req.on("error", function(err){
+  // handle error
+});
+```
+
+##### With request :
+
+```js
+"use strict";
+
+var request = require('request');
+var JSZip = require("jszip");
+
+request({
+  method : "GET",
+  url : "http://localhost/.../file.zip",
+  encoding: null // <- this one is important !
+}, function (error, response, body) {
+  if(error ||  response.statusCode !== 200) {
+    // handle error
+    return;
+  }
+  var zip = new JSZip(body);
+  console.log(zip.file("content.txt").asText());
+});
+```

+title: "How to write a file / give it to the user"
+layout: default
+section: example
+---
+
+### In the browser
+
+With only javascript, this part won't work in old browsers, including IE < 10.
+For those browsers, you can use a flash polyfill, see below.
+
+You can also see this
+[example]({{site.baseurl}}/documentation/examples/download-zip-file.html).
+
+#### Blob URL / FileSaver
+
+With recent browsers, the easiest way is to use `saveAs` or a polyfill, see
+[FileSaver.js](https://github.com/eligrey/FileSaver.js) :
+
+```js
+var blob = zip.generate({type:"blob"});
+saveAs(blob, "hello.zip");
+```
+
+Under the hood, the polyfill uses the native `saveAs` from the
+[FileSaver](http://www.w3.org/TR/file-writer-api/#the-filesaver-interface) API
+(on Chrome and IE10+) or use a [Blob URL](http://updates.html5rocks.com/2011/08/Downloading-resources-in-HTML5-a-download)
+(on Firefox).
+
+
+#### Data URI
+
+For older browsers that support [data URI](http://caniuse.com/datauri), you can also
+do the following :
+
+```js
+location.href="data:application/zip;base64," + zip.generate({type:"base64"});
+```
+
+The biggest issue here is that the filenames are very awkward, Firefox
+generates filenames such as `a5sZQRsx.zip.part` (see bugs
+[367231](https://bugzilla.mozilla.org/show_bug.cgi?id=367231) and
+[532230](https://bugzilla.mozilla.org/show_bug.cgi?id=532230), and Safari
+isn't much better with just `Unknown`.
+
+Browser support and resulting filename :
+
+Opera  | Firefox | Safari | Chrome | Internet Explorer
+-------|---------|--------|--------|------------------
+"default.zip" | random alphanumeric with ".part" extension | "Unknown" (no extension) | "download.zip" on OSX and Linux, just "download" on Windows | No
+
+#### Downloadify
+
+[Downloadify](https://github.com/dcneiner/downloadify) uses a small Flash SWF
+to download files to a user's computer with a filename that you can choose.
+Doug Neiner has added the `dataType` option to allow you to pass a zip for
+downloading. Follow the [Downloadify demo](http://pixelgraphics.us/downloadify/test.html)
+with the following changes:
+
+```js
+zip = new JSZip();
+zip.file("Hello.", "hello.txt");
+Downloadify.create('downloadify',{
+...
+  data: function(){
+    return zip.generate({type:"base64"});
+  },
+...
+  dataType: 'base64'
+});
+```
+
+<!--
+TODO : send data as GET / POST ?
+-->
+
+#### Deprecated google gears
+
+[Franz Buchinger](http://www.picurl.org/blog/author/franz/) has written a
+brilliant tutorial on [using JSZip with Google Gears](http://www.picurl.org/blog/2009/11/22/creating-zip-archives-with-gears)
+([part 2](http://www.picurl.org/blog/2009/11/29/gearszipper-part2-adding-support-for-real-files-and-canvas-elements/)).
+If you want to let your Gears users download several files at once I really
+recommend having a look at some of his [examples](http://picurl.org/gears/zipper/).
+
+
+
+### In nodejs
+
+JSZip can generate Buffers so you can do the following :
+
+```js
+var fs = require("fs");
+var JSZip = require("jszip");
+
+var zip = new JSZip();
+// zip.file("file", content);
+// ... and other manipulations
+
+var buffer = zip.generate({type:"nodebuffer"});
+
+fs.writeFile("test.zip", buffer, function(err) {
+  if (err) throw err;
+});
+```
