pixijs-migration-v8

Migrate PixiJS v7 to v8 by following a checklist-driven workflow: adopt async app.init, replace deprecated @pixi/* imports with single-package pixi.js imports, and update constructor options to resolve breaking changes and prevent broken rendering.

PixiJS Graphics shapes break after upgrading to v8 due to required pattern replacements. You must update Graphics shape-then-fill syntax and apply updated constructor and options-object patterns to achieve correct rendering behavior.

Yes, async Application initialization is required in PixiJS v8. You must await the app.init process instead of using synchronous constructors to properly establish the rendering context and avoid runtime startup failures.

Handle eventMode and ticker changes in PixiJS v8 by applying corrected event handling semantics and fixing ticker callback signature changes, including proper delta handling, to resolve runtime issues after the upgrade.

A key limitation when upgrading is that deprecated @pixi/* imports must be replaced with single-package import rules. Additionally, the DisplayObject base class removal requires updating inheritance patterns to avoid critical migration failures.

Update shader uniforms and textures for PixiJS v8 by enforcing typed shader uniform requirements, applying updated filter constructor patterns, and correcting texture lifecycle updates to prevent visual and runtime errors.
