ruvector-graph-transformer-wasm

Crates.io License: MIT

WebAssembly bindings for RuVector Graph Transformer — proof-gated graph attention, verified training, and 8 specialized graph layers running client-side in the browser.

Run the full graph transformer in any browser tab — no server, no API calls, no data leaving the device. Every graph mutation is formally verified client-side, so your users get the same mathematical safety guarantees as the Rust version. The WASM binary is size-optimized and loads in milliseconds.

Install

# With wasm-pack (recommended)
wasm-pack build crates/ruvector-graph-transformer-wasm --target web

# Or from npm (when published)
npm install ruvector-graph-transformer-wasm

Quick Start

import init, { JsGraphTransformer } from "ruvector-graph-transformer-wasm";

await init();
const gt = new JsGraphTransformer();
console.log(gt.version()); // "2.0.4"

// Proof-gated mutation
const gate = gt.create_proof_gate(128);
const proof = gt.prove_dimension(128, 128);
console.log(proof.verified); // true

// 82-byte attestation for RVF witness chains
const attestation = gt.create_attestation(proof.proof_id);
console.log(attestation.length); // 82

// Sublinear attention — O(n log n)
const result = gt.sublinear_attention(
  new Float32Array([0.1, 0.2, 0.3, 0.4]),
  [{ src: 0, tgt: 1 }, { src: 0, tgt: 2 }],
  4, 2
);

// Verified training step with certificate
const step = gt.verified_training_step(
  [1.0, 2.0], [0.1, 0.2], 0.01
);
console.log(step.weights, step.certificate);

// Physics: symplectic integration
const state = gt.hamiltonian_step([1.0, 0.0], [0.0, 1.0], 0.01);
console.log(state.energy);

// Biological: spiking attention
const spikes = gt.spiking_attention(
  [0.5, 1.5, 0.3], [[1], [0, 2], [1]], 1.0
);

// Manifold: mixed-curvature distance
const d = gt.product_manifold_distance(
  [1, 0, 0, 1], [0, 1, 1, 0], [0.0, -1.0]
);

// Temporal: causal masking
const scores = gt.causal_attention(
  [1.0, 0.0],
  [[1.0, 0.0], [0.0, 1.0]],
  [1.0, 2.0]
);

// Economic: Nash equilibrium
const nash = gt.game_theoretic_attention(
  [1.0, 0.5, 0.8],
  [{ src: 0, tgt: 1 }, { src: 1, tgt: 2 }]
);
console.log(nash.converged);

// Stats
console.log(gt.stats());
