rift-wasm

WebAssembly bindings for browser clients of the riftd P2P protocol.

Part of the riftd project — serverless P2P voice + text chat over UDP.

What's in this crate?

rift-wasm brings rift to the browser:

• WasmClient — Browser-compatible rift client
• E2EE — Encrypt/decrypt messages in the browser
• Voice Encoding — Encode/decode voice frames
• Audio Utilities — Level detection, gain, mixing
• PCM Conversion — Float32 ↔ PCM16 for Web Audio API

Usage

import init, { WasmClient, AudioConfig } from 'rift-wasm';

await init();

const client = new WasmClient();

// Encrypt a message
const encrypted = client.encrypt(plaintext);

// Encode voice for transmission
const encoded = client.encode_voice_pcm(pcmSamples);

// Audio utilities
const level = audio_level(samples);
const isActive = is_voice_active(samples);
