How to create an http3 client or server ?

Node.js Version

I'm testing on v26.0.0-pre, https://github.com/nodejs/node/tree/60f19bc0894eb20f9e525c27b561ef322039382a , but any that has quic.

NPM Version

This does not include NPM.

Operating System

I'm testing on ubuntu 24.04, but any.

Subsystem

Other

Description

I found a file called http3.cc, but after building node with --experimental-quic, I can't find documentation for http3. There is no http3 library like there is http2, and the quic documentation doesn't mention http3.

Minimal Reproduction

1. Open the documentation on github.
2. Try to find http3 documentation, but fail.

Output

There's no http3 documentation, even for --experimental-quic"-built" binaries.

@avivkeller thanks, but that's the quic documentation, and it doesn't mention http/3.

[avivkeller]

QUIC is the transport layer protocol used by HTTP/3, so that's the documentation for our support of the layer, IIUC.

yes, I know, the thing is, there's the http3.cc file I was talking about, so there should be an implementation of http/3 in the C++ source, right ? also, there's deps/ngtcp2/nghttp3, so there should be code that I can import to use the nghttp3 implementation instead of manually writing things like header compression in JavaScript (because the C++ logic runs faster than javascript).

It's not complete yet

oh ok, thanks @jasnell , but I also have a few questions. does the current quic implementation use openssl or quictls ? and nice work on quic and http3, to what extent has the implementation been finished ? also, do you currently have a predicted date of finishing it (sorry if that forced you to do extra work) ?
thank you.
