Thankfully, Pixi.js offers a comparable component known as NineSlicePlane, which resembles Unity’s sliced sprites in function. Although there are few resources and examples available for NineSlicePlane, this article aims to delve deeper into its behavior and outline how it aligns with my expectations.

TL;DR: The code used in this article is available on CodePen.
