@moq/qmux

A WebTransport polyfill for browsers, using WebSockets as the underlying transport with QMux (draft-ietf-quic-qmux-00) framing.

QMux brings QUIC's multiplexed streams and flow control to reliable, ordered byte-stream transports like WebSockets. This allows WebTransport applications to seamlessly fall back when QUIC/UDP is blocked by network middleboxes.

Install

npm install @moq/qmux

Usage

Use as a drop-in WebTransport replacement:

import Session from "@moq/qmux"

const transport = new Session("https://example.com/endpoint")
await transport.ready

const stream = await transport.createBidirectionalStream()

Polyfill

Install as a global WebTransport polyfill:

import { install } from "@moq/qmux"

// Only installs if native WebTransport is unavailable
install()

// Now use the standard WebTransport API
const transport = new WebTransport("https://example.com/endpoint")
