webtransport-go is an implementation of the WebTransport protocol, based on [quic-go](https://github.com/quic-go/quic-go). It currently implements [draft-02](https://www.ietf.org/archive/id/draft-ietf-webtrans-http3-02.html) of the specification.
|
|
|
|
## Running a Server
|
|
|
|
```go
|
|
// create a new webtransport.Server, listening on (UDP) port 443
|
|
s := webtransport.Server{
|
|
H3: http3.Server{Addr: ":443"},
|
|
}
|
|
|
|
// Create a new HTTP endpoint /webtransport.
|
|
http.HandleFunc("/webtransport", func(w http.ResponseWriter, r *http.Request) {
|
|
conn, err := s.Upgrade(w, r)
|
|
if err != nil {
|
|
log.Printf("upgrading failed: %s", err)
|
|
w.WriteHeader(500)
|
|
return
|
|
}
|
|
// Handle the connection. Here goes the application logic.
|
|
})
|
|
|
|
s.ListenAndServeTLS(certFile, keyFile)
|
|
```
|
|
|
|
Now that the server is running, Chrome can be used to establish a new WebTransport session as described in [this tutorial](https://web.dev/webtransport/).
|
|
|
|
## Running a Client
|
|
|
|
```go
|
|
var d webtransport.Dialer
|
|
rsp, conn, err := d.Dial(ctx, "https://example.com/webtransport", nil)
|
|
// err is only nil if rsp.StatusCode is a 2xx
|
|
// Handle the connection. Here goes the application logic.
|
|
```
