# A QUIC implementation in pure Go [![Godoc Reference](https://img.shields.io/badge/godoc-reference-blue.svg?style=flat-square)](https://godoc.org/github.com/lucas-clemente/quic-go) [![Linux Build Status](https://img.shields.io/travis/lucas-clemente/quic-go/master.svg?style=flat-square&label=linux+build)](https://travis-ci.org/lucas-clemente/quic-go) [![Windows Build Status](https://img.shields.io/appveyor/ci/lucas-clemente/quic-go/master.svg?style=flat-square&label=windows+build)](https://ci.appveyor.com/project/lucas-clemente/quic-go/branch/master) [![Code Coverage](https://img.shields.io/codecov/c/github/lucas-clemente/quic-go/master.svg?style=flat-square)](https://codecov.io/gh/lucas-clemente/quic-go/) quic-go is an implementation of the [QUIC](https://en.wikipedia.org/wiki/QUIC) protocol in Go. ## Roadmap quic-go is compatible with the current version(s) of Google Chrome and QUIC as deployed on Google's servers. We're actively tracking the development of the Chrome code to ensure compatibility as the protocol evolves. In that process, we're dropping support for old QUIC versions. As Google's QUIC versions are expected to converge towards the [IETF QUIC draft](https://github.com/quicwg/base-drafts), quic-go will eventually implement that draft. ## Guides We currently support Go 1.7+. Installing deps: go get -t Running tests: go test ./... ### Running the example server go run example/main.go -www /var/www/ Using the `quic_client` from chromium: quic_client --host=127.0.0.1 --port=6121 --v=1 https://quic.clemente.io Using Chrome: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --user-data-dir=/tmp/chrome --no-proxy-server --enable-quic --origin-to-force-quic-on=quic.clemente.io:443 --host-resolver-rules='MAP quic.clemente.io:443 127.0.0.1:6121' https://quic.clemente.io ### Using the example client go run example/client/main.go https://clemente.io ## Usage ### As a server See the [example server](example/main.go) or try out [Caddy](https://github.com/mholt/caddy) (from version 0.9, [instructions here](https://github.com/mholt/caddy/wiki/QUIC)). Starting a QUIC server is very similar to the standard lib http in go: ```go http.Handle("/", http.FileServer(http.Dir(wwwDir))) h2quic.ListenAndServeQUIC("localhost:4242", "/path/to/cert/chain.pem", "/path/to/privkey.pem", nil) ``` ### As a client See the [example client](example/client/main.go). Use a `QuicRoundTripper` as a `Transport` in a `http.Client`. ```go http.Client{ Transport: &h2quic.QuicRoundTripper{}, } ``` ## Contributing We are always happy to welcome new contributors!
