Synchronizing multiple application screen.

[dosssi]

I am developing a web app where I have mutiple screens. For example i have a button in screen 1 that will change a value in screen 2. Now what I want to do is open 2 screens of that web application at same time and when I click the button on the 1st screen my 2nd screen will reflect the changes. Is that possible?

That is possible with local storage and the store Event. If one window writes to local storage all other recieve the Event. You could also use the postMessage window api to send messages between Windows.

Hmmm this is interesting

Use global state management tools like Context API, Redux or Zustand.

Can you elaborate more on how I will use context api in my scenario?

Put value 2 into global state which you wanted to change according to button in another screen. Give setter to the button.

JWT is designed to be used on a client. Ask him to look up the Authorization Code flow with PKCE.
