GPUix Solid: Solid 2 Bindings for Native GPU Interfaces

GPUix Solid is an independently implemented Solid 2 renderer built against GPUIX’s public native mutation contract. It connects Solid’s compiler and runtime to GPUI, the GPU-accelerated UI framework used by Zed. The native bridge stays in @gpuix/native, so the project does not fork the Rust layer.

Renderer architecture

Solid updates affected host properties and children. The renderer records those changes in a small JavaScript shadow tree, then batches mutations into GPUIX’s retained native tree:

Solid signal → universal renderer → JS shadow tree
                         → batched N-API mutations → Rust retained tree → GPUI

The shadow tree answers Solid’s synchronous parent, firstChild, and nextSibling queries. Native rendering stays retained and batched.

Current milestone

Milestones M0 through M5 are complete. They cover renderer integration, root-scoped ownership, event and ref handling, hot remounts, native element parity, focus and selection, native animations, and Solid-native Tooltip, Select, and Combobox components. The repository also includes a GPU-backed test renderer, screenshot parity coverage, and a Playwright-like native automation API with live stdio transport.

M6 covers release hardening, cross-platform CI, compatibility documentation, versioning, npm provenance, and beta publication. The project is independent of GPUIX, Zed, and SolidJS. It tests Solid’s programming model against native GPU interfaces.
