HTTP/3 and raw QUIC client/server APIs for Node.js

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/http3 It’s a native package around Rust/quiche.

In plain words

This is a native Node.js package providing HTTP/3 and raw QUIC client and server APIs built on Rust's quiche library. Developers can create outbound and accept inbound QUIC connections directly from Node.js code without recompiling Node or using a reverse proxy. It supports raw QUIC streams, datagrams, custom ALPN protocols, and session management, written with a focus on memory safety through Rust.

In the maker’s words, at launch

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/http3 It’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.

    Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
