Wickra Genome — WASM

Part of the Wickra ecosystem: — for WASM. npm install wickra-genome-wasm — pure WebAssembly, runs anywhere a modern JS engine does.

WebAssembly bindings for the Wickra Genome vector engine, compiled from Rust with wasm-bindgen. A Genome is built from a spec JSON and driven by command JSONs over a JSON boundary, so a browser front-end runs against the exact same core as every other Wickra Genome binding.

Install

npm install wickra-genome-wasm

Building from this repository (contributors)

wasm-pack build --target web      # for a browser bundler
wasm-pack build --target nodejs   # for node:test / Node.js

The output lands in pkg/.

Quick start

import init, { Genome } from "wickra-genome-wasm";

await init();

const spec = JSON.stringify({
  features: [{ kind: "price", field: "close" }],
  symbols: ["AAA", "BBB", "CCC"],
  normalize: "z_score",
  metric: "euclid",
  seed: 24333,
});
const g = new Genome(spec);

const data = {
  AAA: [{ time: 0, open: 1, high: 1, low: 1, close: 1, volume: 0 }],
  BBB: [{ time: 0, open: 2, high: 2, low: 2, close: 2, volume: 0 }],
  CCC: [{ time: 0, open: 100, high: 100, low: 100, close: 100, volume: 0 }],
};
g.command(JSON.stringify({ cmd: "build", data }));

console.log(g.command(JSON.stringify({ cmd: "similar", symbol: "AAA", k: 2 })));

The engine runs single-threaded in the browser, and because every cross-section reduction runs serially in key order, the result is byte-identical to the native parallel run — the exact cross-language golden check.

Benchmark

Every binding forwards to the same data-driven Rust core, so what this one adds is the call overhead of wasm-bindgen, not a different result. The core's throughput is measured by the repository's benchmark suite and the nightly bench.yml run; the numbers, the machine and how to reproduce them are in the repository BENCHMARKS.md.

Documentation

The full guide, the spec reference and the API documentation live in the main repository and the documentation site:

• Repository: https://github.com/wickra-lib/wickra-genome
• Docs (guides, spec reference, cookbook): https://genome.wickra.org
• Runnable example: examples/wasm/

Wickra Genome ships native bindings for Python, Node.js, WASM and Rust, plus a C ABI hub that any C-capable language (C, C++, C#, Go, Java, R) links against — all forwarding to the same data-driven, unsafe-forbidden Rust core.
