I built this because I wanted to make outbound and accept inbound HTTP/3 and raw QUIC connections from ordinary Node.js code, without building Node from source or putting everything behind a reverse proxy.Repo: https://github.com/currentspace/http3 npm: https://www.npmjs.com/package/@currentspace/http3It’s a native package around Rust/quiche. It supports both client and server APIs, I'm using it in a couple of projects: creating raw QUIC streams, datagrams, custom ALPN, session behavior, and HTTP/3 client work from Node.I've tried to be very safe in the native code, written in rust, with proofs around the parts I was most concerned about getting wrong. I have it hosting a couple of sites as HTTP3 endpoints and found it working well.

Could you build this?
Partial Wrapping an established C/C++ QUIC library like nghttp3/ngtcp2 as a Node.js native addon is achievable, but handling memory management, non-blocking asynchronous event loops, and QUIC stream lifecycles requires specialized native systems knowledge.
What it would actually take: The architecture relies on Node-API (N-API) binding a battle-tested C library (such as ngtcp2/nghttp3 or Cloudflare's Quiche) to Node's libuv event loop. The challenging elements are zero-copy buffer transfers between JavaScript and native memory, handling UDP socket polling without blocking, and managing connection state machines across threads.
