Node.js

A native napi-rs addon: the same Rust core, no subprocess and no serialization beyond the command envelope itself.

npm install wickra-benchmark

const fs = require("node:fs");
const { Benchmark, version } = require("wickra-benchmark");

const theCase = JSON.parse(fs.readFileSync("cases/sma-crossover-01.json", "utf8"));
const data = [/* the dataset's candles */];

const bench = new Benchmark();
const result = JSON.parse(
  bench.command(JSON.stringify({ cmd: "run_case", case: theCase, data })),
);
console.log(version(), result.passed, result.hash_match);

The command surface

Every binding exposes the same four commands and returns the core's canonical JSON string verbatim. That is what makes byte equality the cross-language check.

cmd	Payload	Response
run_case	{case, data}	a CaseResult — passed, hash_match, hash, recomputed
run_suite	{suite, datasets}	a SuiteReport — the results sorted by id, plus the tally
list_cases	{suite}	{"ids": [...]}, sorted
version	—	{"version": ..., "engine_version": ...}

A domain error — a malformed case, an unknown command — comes back in-band as {"ok":false,"error":...} rather than as an exception.

One committed example of every envelope lives in golden/commands/, with the exact response each must produce beside it in golden/expected/.
