TypeScript Installation

The TypeScript SDK runs in three environments from the same package:

Browsers — uses native WebTransport
Node 20+ — uses a WebTransport polyfill
Bun — native (Bun ships WebTransport)

All three environments load the same Emscripten WASM build of the C++ core for serialization and audio framing.

Install

npm install @clutchcall/sdk

pnpm add @clutchcall/sdk

bun add @clutchcall/sdk

Subpath imports

Each of the five modalities is its own subpath import:

import { Voice }      from "@clutchcall/sdk/voice";
import { Streams }    from "@clutchcall/sdk/streams";
import { Robotics }   from "@clutchcall/sdk/robotics";
import { Games }      from "@clutchcall/sdk/games";
import { Data }       from "@clutchcall/sdk/data";
import { MoqtClient } from "@clutchcall/sdk/moqt";

The root import (import … from "@clutchcall/sdk") is the legacy ClutchCallClient voice-RPC surface. It stays available for backwards compatibility.

Verify

import { MoqtClient } from "@clutchcall/sdk/moqt";

const moqt = await MoqtClient.connect("https://relay.clutchcall.dev/moq");
console.log("connected, rtt:", moqt.connectionRttUs(), "µs");
moqt.close();
