How to retain cookies in node-webkit

Question

I wish to create an application using node-webkit which does the simple job to open a remote web application. The web application has some cookie based authentication. Considering that the user has signed-in successfully, how can the required cookies be retained, so that the next time the application runs, the user will be authenticated?

Answer 1

1. You can get auth cookies using this instructions: https://github.com/nwjs/nw.js/wiki/window#windowcookies

2. Save it with prefered method: https://github.com/nwjs/nw.js/wiki/Save-persistent-data-in-app

3. On next start just check that record exists, and set cookies with method from 1.

Should be something like this:

var gui = require('nw.gui');
var win = gui.Window.get();

function login() {
   var opts = {};
   if(localStorage.auth) {
      opts.cookies: [
           'Auth': localStorage.auth
      ];
   }

    someRequest.get(opts, function(result) {
        if(result)
          localStorage.auth = win.cookies.get('auth');
    });
}

As of 2018, NW.js retains cookies and other persistent browser data by default. These are stored in %LOCALAPPDATA%/name-in-manifest/ in Windows or equivalent depending on OS. Nothing is required from the application itself, you do not have to persist cookie data manually in local storage.
