Media over QUIC (MoQ) is a live (media) delivery protocol utilizing QUIC. It utilizes new browser technologies such as [WebTransport](https://developer.mozilla.org/en-US/docs/Web/API/WebTransport_API) and [WebCodecs](https://developer.mozilla.org/en-US/docs/Web/API/WebCodecs_API) to provide WebRTC-like functionality. Despite the focus on media, the transport is generic and designed to scale to enormous viewership via clustered relay servers (aka a CDN). See [quic.video](https://quic.video) for more information. **Note:** this project is a [fork](https://quic.video/blog/transfork) of the [IETF specification](https://datatracker.ietf.org/group/moq/documents/). The principles are the same but the implementation is exponentially simpler given a narrower focus (and no politics). # Usage This library contains just the generic transport. More documentation will be available later, until then refer to the code. ```ts import * as Moq from "@kixelated/moq"; const conn = await Moq.Connection.connect(new URL("http://localhost:4443/")); // Optional: Discover broadcasts matching a prefix. const announced = conn.announced("demo/"); for (;;) { const announce = await announced.next(); if (!announce) break; console.log("discovered broadcast:", announce.path); // NOTE: This code is untested and the API is subject to change. const broadcast = conn.consume(`demo/${announce.path}`); const track = broadcast.subscribe("catalog.json"); // A track can have multiple groups (unordered+unreliable). const group = await track.nextGroup(); // A group can have multiple frames (ordered+reliable). const frame = await group.nextFrame(); // This is a Uint8Array; but the contents are actually JSON. console.log("received frame:", frame); // Don't forget to close to release resources. frame.close(); group.close(); track.close(); broadcast.close(); } ``` # License Licensed under either: - Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) - MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT)
