Hey Saransh,

Not really sure if I got you.

But you can do this 

1. On Ready action for the screen add a javascript node with the following JS code:
2. window.addEventListener('resize', function(event) {    $actions.Action1()}, true);
3. build a client action with the logic that you need and replace the action1() by your action name

Hope I could help.

Following Davide's answer, you could use the Resize Observer API, witch has some advantages over the  convencional window.addEventListener.
