jsimd workspace

This repository is a monorepo for small WebAssembly SIMD data structures and the higher-level libraries built from them.

Package	Responsibility	Status
@mizchi/jsimd	Tree-shakeable SIMD kernels and data structures	Published
@mizchi/jsimd-shared	SharedArrayBuffer and Web Worker primitives	Compatibility facade
@mizchi/jsimd-columnar	Typed schema and page storage engine	Experimental
@mizchi/jsimd-olap	Parallel analytical execution over typed columns	Experimental
@mizchi/jsimd-bench	Reproducible Node and browser benchmark records	Internal

Higher-level vector-search and WebGPU work remains under experiments until its public API and dispatch policy are stable. Runnable integrations remain under examples.

Development

Node.js 24.5 or newer, Deno 2.6 or newer, pnpm, just, wasm-tools, and Vite 8 are required.

pnpm install
just check

The current compatibility dependency direction is intentionally one-way:

@mizchi/jsimd ── @mizchi/jsimd-shared
       │
       └──────── @mizchi/jsimd-columnar

@mizchi/jsimd-shared + @mizchi/jsimd-columnar
       └──────── @mizchi/jsimd-olap

packages
       └──────── parallel experiments

Experiments may depend on any package. Published packages must not depend on experiments.
