@vizij/arora-web-wasm

Run a Vizij runtime in the browser as an Arora device.

The wasm module (built from crates/interop/vizij-arora-web) assembles an arora-web BrowserRuntime over the Vizij interop seams — a blackboard store, a rig HAL, and your node graph as the device's behavior. One device, one store, one step loop: the graph reads its input nodes' paths from the store each tick and writes its outputs back, and JS talks to the same store.

Use

import { init, startDevice } from "@vizij/arora-web-wasm";

await init();
const device = await startDevice(graphSpec); // a Vizij graph spec (object or JSON)

// each animation frame (dt in ms, e.g. from requestAnimationFrame timestamps):
device.setValue("sensor/x", { f32: 0.75 });
device.step(dtMs);
const changes = device.drainChanges(); // path -> ValueJSON | null

device.dispose();

Values cross the boundary in the normalized ValueJSON vocabulary from @vizij/value-json; setValue/writeValues accept its ValueInput shorthands.

Build

The pkg/ wasm artifacts are produced by wasm-pack from the repository root:

pnpm run build:wasm:arora-web   # wasm-pack build -> npm/@vizij/arora-web-wasm/pkg
pnpm --filter @vizij/arora-web-wasm run build
