A QUIC implementation in pure Go
quic-go is an implementation of the QUIC protocol (RFC 9000, RFC 9001, RFC 9002) in Go, including the Unreliable Datagram Extension (RFC 9221) and Datagram Packetization Layer Path MTU Discovery (DPLPMTUD, RFC 8899). It has support for HTTP/3 (RFC 9114), including QPACK (RFC 9204).
In addition to the RFCs listed above, 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 1.18.x and Go 1.19.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{},
