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	SIMD kernels, Float32 fusion, and data structures	Published
@mizchi/jsimd-shared	SharedArrayBuffer and Web Worker primitives	Compatibility facade
@mizchi/jsimd-moonbit-interop	MoonBit JS-backend view adapters	Compatibility facade
@mizchi/jsimd-validator	Wasm SIMD validation for typed numeric arrays	Release candidate
@mizchi/jsimd-validator-compiler	Schema-specialized Wasm SIMD AOT compiler	Release candidate
@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-moonbit-interop
       │
       └──────── @mizchi/jsimd-columnar

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

@mizchi/jsimd-validator (dependency-free)
@mizchi/jsimd-validator-compiler (build-time only)

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

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

Validator package release operations are documented in docs/validator-release.md. Wasm AOT benchmark and supported-schema details live with the validator compiler.
