var fs = require("fs");
var JSZip = require("jszip");

// read a zip file
fs.readFile("test.zip", function(err, data) {
    if (err) throw err;
    JSZip.loadAsync(data).then(function (zip) {
        // ...

// or
new JSZip.external.Promise(function (resolve, reject) {

        } else {
            resolve(data);
        }
    });
}).then(function (data) {
    return JSZip.loadAsync(data);

.then(...)


// 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);
});
// or
var contentPromise = new JSZip.external.Promise(function (resolve, reject) {
    fs.readFile("picture.png", function(err, data) {

            reject(e);
        } else {
            resolve(data);
        }
    });
});
zip.file("picture.png", contentPromise);


// read a file as a stream and add it to a zip
var stream = fs.createReadStream("picture.png");
zip.file("picture.png", stream);
