959: TypeScript on the GPU with TypeGPU creator Iwo Plaza

25 minutes Posted Dec 1, 2025 at 12:00 pm.

Welcome to Syntax!

What is TypeGPU? High-level overview and why it exists

WebGPU vs WebGL – the new era of GPU access on the web

Why shader languages are hard + making them accessible

Iwo’s background in C++, OpenGL, and discovering JS

Sharing graphics work on the web vs native platforms

WebGPU frustrations that inspired TypeGPU

Making GPU–CPU data exchange easier with Zod-like schemas

Writing shaders in JavaScript + the unified type system

How the “use_gpu” directive works under the hood

Building a compiler that turns TypeScript into shader code

Type inference, primitives, structs, and TypeScript magic

Leveraging existing tooling via Unplugin + bundler integration

How TypeGPU extracts ASTs and generates TinyEST metadata

Runtime shader generation vs build-time macros

How the AST is traversed + maintaining transparency in output

Example projects like Jelly Shader and community reception

Does TypeGPU replace 3JS? How it fits the existing ecosystem

Low-level control vs high-level abstractions

Upcoming Three.js integration – plugging TypeGPU into materials compute shaders

Making GPU development more approachable

Docs, examples, and the philosophy behind TypeGPU documentation

Building features by building examples first

Using examples as a test suite + how docs shape API design

Docs as a forcing function for intuitive APIs

GPU for AI – browser inference and future abstractions

How AI examples inform new libraries (noise, inference, etc.)

Keeping the core package small and flexible

Building “TypeGPU AI”-style extensions without bloating the core

The cost of AI examples and building everything from scratch

Standard library design and future of the ecosystem

Closing thoughts from Iwo – OSS, GPU renaissance, and encouragement

Scott and CJ sit down live at JSNation NYC with Iwo Plaza, creator of TypeGPU, to dig into how WebGPU is unlocking a new wave of graphics and compute power on the web. They chat about shader authoring in TypeScript, the future of GPU-powered AI in the browser, and what it takes to build a killer developer-friendly graphics library.
