WASM

The WebAssembly build runs the same Rust core in the browser or any WASM runtime. Construct a TimeMachine, load records, then seek — over command(json) -> json.

npm install wickra-timemachine-wasm

import init, { TimeMachine } from 'wickra-timemachine-wasm'

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

const tm = new TimeMachine('{}')
const records = '{"ts":10,"symbol":"BTC-USDT","feed":{"kind":"market","type":"trade","price":"100","quantity":"1"}}'
tm.command(JSON.stringify({ cmd: 'load', data: records }))
const snapshot = JSON.parse(tm.command(JSON.stringify({ cmd: 'seek', ts: 10 })))
console.log(snapshot)

Seeking to a given timestamp yields a snapshot byte-identical to the native build. See the live demo for the Wickra core running in your browser.
