Change screen size on browser resized?

[gaelbeltran]

I'm using this method to make the game fit the screen on the create() method:

game.stage.ScaleMode = Phaser.StageScaleMode.EXACT_FIT;

game.stage.scale.setExactFit();

game.stage.scale.refresh();

 

But how can I make the screen resize when the browser resizes? 

 

I can make it work by putting this code on the update() method but is there a more efficient way to do this than making that code fire every frame?
