Shipping shaders on a typical web team is still a bottleneck. WebGPU gives you raw hardware access but forces you to manage adapters, bind group layouts, pipeline descriptors, and a tangle of state before you see a single pixel. Teams end up writing boilerplate that drifts out of sync, debugging opaque errors, and struggling to test rendering in CI or headless environments.
vgpu solves these pain points by treating .wgsl files as first‑class TypeScript modules. You import a shader just like any other code, and the library resolves the module graph, reflects bindings, strips unused declarations, and emits an optimized shader at build time. No more manual binding layouts that fall out of date.
The API is deliberately simple: a single init() call returns a Gpu context. From there you create a surface for a canvas, load an effect with gpu.effect(shader, uniforms), and drive the render loop with explicit frame calls—passes, clears, and draws are all ordinary functions, not hidden scene‑graph state. The same context works in the browser, in a Dawn‑powered Node.js process for offscreen rendering, and in a deterministic mock adapter for pure‑unit tests.
Because the library includes pixelmatch and pngjs as dependencies, CI pipelines can compile a shader, render a headless frame, and compare the output to a snapshot with virtually no setup. The MIT‑licensed package is available on npm; a single pnpm add vgpu gets you the core library, a CLI (npx vgpu docs, npx vgpu examples, npx vgpu check), llms.txt, and a hosted read‑only MCP endpoint. The bundled binary lets you run documentation or checks without a global install.
Teams now get a lightweight, 25 KB gzipped fullscreen effect, a shader‑first workflow, and reliable testing across browsers, Node, and CI—all with one clear API and no hidden costs.
