load(data [, options])

Description : Read an existing zip and merge the data in the current JSZip object at the current folder level. This technique has some limitations, see here.

Arguments

name	type	description
data	String/ArrayBuffer/Uint8Array/Buffer	the zip file
options	object	the options to load the zip file

Content of options :

name	type	default	description
options.base64	boolean	false	set to `true` if the data is base64 encoded, `false` for binary.
options.checkCRC32	boolean	false	set to `true` if the read data should be checked against its CRC32.
options.optimizedBinaryString	boolean	false	set to true if (and only if) the input is a string and has already been prepared with a 0xFF mask.

You shouldn't update the data given to this method : it is kept as it so any update will impact the stored data.

Zip features supported by this method :

Compression (DEFLATE supported)
zip with data descriptor
ZIP64
UTF8 in file name, UTF8 in file content

Zip features not (yet) supported :

password protected zip
multi-volume zip

Returns : The current JSZip object.

Throws : An exception if the loaded data is not valid zip data or if it uses features (multi volume, password protected, etc).

Example

var zip = new JSZip();
zip.load(zipDataFromXHR);

require("fs").readFile("hello.zip", function (err, data) {
  if (err) throw err;
  var zip = new JSZip();
  zip.load(data);
}

Using sub folders :

var zip = new JSZip();
zip.folder("subfolder").load(data);
// the content of data will be loaded in subfolder/
