WASM

The WebAssembly build runs the same Rust core in the browser or any WASM runtime. Construct a Darwin from a JSON spec and drive it with command(json) -> json.

bash

npm install wickra-darwin-wasm

javascript

import init, { Darwin } from 'wickra-darwin-wasm'

await init() // fetches and instantiates the .wasm module

const spec = JSON.stringify({
  seed: 1, population: 8, generations: 3,
  mutation_rate: 0.2, crossover_rate: 0.6, fitness: 'sharpe',
  search_space: { indicators: [{ name: 'rsi', param_ranges: [{ min: 2, max: 30, step: 1 }] }], rules: 'single_threshold', max_conditions: 1 },
  elitism: 1, top: 5,
})

const darwin = new Darwin(spec)
const data = { BTCUSDT: [{ time: 1700000000, open: 100, high: 101, low: 99, close: 100.5, volume: 10 }] }
const report = JSON.parse(darwin.command(JSON.stringify({ cmd: 'evolve', data })))
console.log(report.best[0].fitness)

The same seed yields a report byte-identical to the native build. See the live demo for the Wickra core running in your browser.
