A QUIC implementation in pure Go

Note: this repository is a temporary fork of lucas-clemente/quic-go to experiment with and figure out our needs in terms of mapping an http3 request with the five tuple used by the underlying http3 connection. We described this experiment in the ooni/probe#2220 issue. The general plan here is to understand what we exactly need and then see whether it's possible to upstream the changes.

We started this fork at lucas-clemente/quic-go@v0.27.0. We're not going to publish all the upstream tags for simplicity. When merging from upstream, we'll clarify which tags we're merging.

(You should not depend on this repository! As mentioned, this is an experiment and we may archive this repository anytime soon!)

---

quic-go is an implementation of the QUIC protocol, RFC 9000 protocol in Go. In addition to RFC 9000, it currently implements the IETF QUIC draft-29. Support for draft-29 will eventually be dropped, as it is phased out of the ecosystem.

Guides

We currently support Go 1.16.x, Go 1.17.x, and Go 1.18.x.

Running tests:

go test ./...

QUIC without HTTP/3

Take a look at this echo example.

Usage

As a server

See the example server. Starting a QUIC server is very similar to the standard lib http in go:

http.Handle("/", http.FileServer(http.Dir(wwwDir)))
http3.ListenAndServeQUIC("localhost:4242", "/path/to/cert/chain.pem", "/path/to/privkey.pem", nil)

As a client

See the example client. Use a http3.RoundTripper as a Transport in a http.Client.

http.Client{
  Transport: &http3.RoundTripper{},
}
