In order to make a variable "sharable", you would require some server-side component to facilitate it.
Alternatively, consider utilizing PouchDB for this purpose.
Here's an example from the documentation:
var db = new PouchDB('dbname');
db.put({
_id: '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="680c091e0d280f05090104460b0705">[email protected]</a>',
name: 'David',
age: 69
});
db.changes().on('change', function() {
console.log('Ch-Ch-Changes');
});
If both instances are on the same domain, this approach should work effectively.
Utilizing built-in developer tools may not allow you to achieve this, but there is a workaround using Tampermonkey, an extension that enables cross-domain storage and more. By setting up Tampermonkey to create an interface on the window for data manipulation as shown below:
// ==UserScript==
// @name Shared Data
// @include *
// @grant GM_setValue
// @grant GM_getValue
// ==/UserScript==
unsafeWindow.set = (prop, val) => GM_setValue(prop, val);
unsafeWindow.get = (prop) => GM_getValue(prop);
You can then easily set and retrieve values across domains by simply typing in set and get commands into the console:
