bindings/node had no examples/ directory — the README pointed at a test file as its "Example". (bindings/wasm/examples/index.html already exists and is a complete browser demo, so only the Node side was missing.) Add bindings/node/examples/streaming.js: a deterministic synthetic price series fed tick by tick through SMA, EMA, RSI and MACD, printing a status line and flagging overbought/oversold candidates — the same O(1)-per-update streaming model a live bot would use. Verified against the built native module.
@wickra/wickra
Node.js bindings for the Wickra streaming-first technical indicators library.
Install
Once published, install per platform via the precompiled native package:
npm install @wickra/wickra
Build from source
cd bindings/node
npm install
npm run build
npm test
The native module is built via napi-rs. The build script
produces a wickra.<platform>-<arch>.node binary in the package root that
index.js loads at runtime.
Usage
import { SMA, RSI, MACD, version } from '@wickra/wickra';
console.log('wickra', version());
// Batch:
const prices = Array.from({ length: 1000 }, (_, i) => 100 + Math.sin(i * 0.1) * 5);
const rsi = new RSI(14).batch(prices);
// Streaming:
const macd = new MACD(12, 26, 9);
for (const p of livePriceStream) {
const v = macd.update(p);
if (v && v.histogram > 0) console.log('bullish crossover candidate');
}
