is it possible to reach a variable / function from another page ?

[BilalKhatib]

I have 2 pages : Page1.html and Page2.html

Page1.html has a declared variable and function in it

username : 'admin',

welcomeUser() {
     console.log('Welcome Back  ' + this.username)
},

i need to access those function and variable in my Page2.html createApp
Any help ?

I use this in page1:

 window.localStorage.setItem(key, value);

in page2:

let state = window.localStorage.getItem(key)

I'll assume your app is multi pages, another approach might be using query string,

in page1,

const url = new URL("page2");
url.searchParams.set("username", 'admin'); 
location.href = url.href   

then you retrieve the 'username' in page2 before createApp

if you want the passing of variables like SPA, then the regular Vue is a better option
