A QUIC implementation in pure Go

quic-go is an implementation of the QUIC protocol in Go. It implements the IETF QUIC draft-29 and draft-32.

Version compatibility

Since quic-go is under active development, there's no guarantee that two builds of different commits are interoperable. The QUIC version used in the master branch is just a placeholder, and should not be considered stable.

If you want to use quic-go as a library in other projects, please consider using a tagged release. These releases expose experimental QUIC versions, which are guaranteed to be stable.

Guides

We currently support Go 1.14+, with Go modules support enabled.

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{},
}
