Wickra X-Ray — WASM

▶ Live demo: all 514 indicators over real Binance market data, computed live in your browser — live.wickra.org · zero backend, powered by wickra-wasm.

A free explorer that shows, historically, what only Wickra computes — for WASM. npm install wickra-xray-wasm — pure WebAssembly, runs anywhere a modern JS engine does.

WASM bindings for the wickra-xray data-driven core, compiled to WebAssembly with wasm-bindgen. Build an Xray from a spec JSON, drive it with command JSON, read back render frames — the same protocol as every other binding, running in the browser. This is the binding the reference web/ front-end renders.

The core is built with --no-default-features, so the panels build sequentially (no rayon thread pool in the browser sandbox) and byte-identical to the native parallel build.

Install

npm install wickra-xray-wasm

Building from this repository (contributors)

wasm-pack build --target web

This emits pkg/ with the .wasm module and JS glue.

Quick start

import init, { Xray, version } from "wickra-xray-wasm";

await init();

const spec = JSON.stringify({
  dataset_ref: "mini", symbol: "AAA",
  panels: [{ kind: "footprint", price_bin: 1.0, bucket_ms: 60000 }],
});

const xray = new Xray(spec);
xray.command(JSON.stringify({ cmd: "load", dataset: {
  trades: [{ ts: 1000, price: 100.4, qty: 2.0, side: "buy" }],
}}));
const frame = JSON.parse(xray.command(JSON.stringify({ cmd: "frame" })));

console.log(frame.symbol, frame.cursor_ts);
console.log(version());

API

| Member | Description | |--------|-------------| | new Xray(specJson) | Build an xray from a spec JSON (throws on an invalid spec). | | xray.command(cmdJson) | Apply a command JSON, return the response JSON. | | xray.version() / version() | The library version. |

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-xray
• Docs (guides, spec reference, cookbook): https://xray.wickra.org
• Runnable example: examples/wasm/

Wickra X-Ray 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.
