moq-js (video-dev)

2026-05-29: No new activity May 28-29. PR #72 itzmanish refactor still OPEN no new commits or reviews since May 26 12:49 UTC. Day +3 of the OPEN window with no engagement from englishm/Cloudflare maintainers. The 155-day stewardship lag pattern (PR #121 in cloudflare/moq-rs) is the structural risk worth tracking: if PR #72 follows the same pattern, it will not merge before London (now 11 days away).

2026-05-28: PR #72 OPEN since May 26 12:49 UTC by itzmanish (Manish) “Refactor project structure and APIs” (+11205/−22195 across draft-16 baseline) — massive code reorganization. Same external contributor whose PR #121 in cloudflare/moq-rs took 155 days to merge (Dec 18 2025 → May 20 2026) and whose PR #131 (draft-16 implementation) is still open in cloudflare/moq-rs. Manish is now a structural cross-impl contributor across both Cloudflare-stewarded MoQ TypeScript/Rust stacks. Carry-forward: net delta -10990 LOC (deletions far exceed additions) suggests Manish is consolidating moq-js around a simpler core API surface; whether englishm/Cloudflare merges before London is the open question — the prior 155-day stewardship lag pattern is a structural risk.

Overview

IETF-aligned JavaScript/browser implementation of MoQ Transport, enabling browser-based publishing and subscribing via WebTransport. Client-side only — requires a MoQ relay such as moq-rs for operation.

History

Created 2024-10-15, the same day as moq-rs (cloudflare/moq-rs). Both were born out of the period when luke-curley was not going to support the IETF WG specs in his original kixelated/moq-js. The video-dev version started from Luke’s codebase but diverged to follow the IETF MoQ working group specifications. Luke’s original kixelated/moq-js was archived in June 2025 and its functionality was absorbed into moq-dev as the Hang player (a total rewrite).

Much of the post-fork development came from the Montevideo Tech Summer Camp 2025 “MoQ Player Implementation” project, with Mike English as technical sponsor and contributors from the Qualabs community. The repo was moved from englishm/moq-js to video-dev/moq-js to reflect its status as a community project. The 2026 Summer Camp continued MoQ work with both Mike English and Luke Curley as co-technical sponsors, this time focused on moq-dev/moq.

The two JS projects are now separate implementations — video-dev/moq-js follows IETF WG specs, while moq-dev/moq’s JS packages implement Luke’s moq-lite/Hang protocol.

Recent Activity (April 2026)

• PR #70 (Apr 20, Manish / @itzmanish): “fix: moq-js player lifecycle and browser audio playback” — +9542/−6440. Reworks lib/playback/worker/audio.ts for browser audio handling, extends <video-moq> lifecycle, and updates the subscriber transport plumbing. The volume comes mostly from deleting the legacy web/ blog site and bundling a fresh demo/lib/publish.iife.js. First substantive moq-js PR since mid-April.
