How to create glow effect in phaser 3

Looking to achieve glow like phaser 2 Phaser - Examples - Filters - Rainbow Bars
in Phaser 3.

Is there a way to achieve this, please.

I think the Phaser v2 example code you are referring to is using shader code.

I’m not familiar with shaders, but there are some Phaser 3 examples here

Very difficult to achieve the glow around a sprite or image with shaders. You are closer though. Thank you.
