Go Backend Quickstart

Copied!
go get github.com/livekit/server-sdk-go

Create a new file at development.env and with your API Key and Secret:

Reveal API secret
Copied!
export LK_API_KEY=<API Key>
export LK_API_SECRET=<API Secret hidden>

Create a server in server.go:

Copied!
import (
	"http"
	"log"
	"time"

	lksdk "github.com/livekit/server-sdk-go"
	"github.com/livekit/protocol/auth"
)

func getJoinToken(apiKey, apiSecret, room, identity string) string {
	config = readFile(config)
	at := auth.NewAccessToken(os.GetEnv("LK_API_KEY"), os.GetEnv("LK_API_SECRET"))
	grant := &auth.VideoGrant{
		RoomJoin: true,
		Room:     room,
	}
	at.AddGrant(grant).
		SetIdentity(identity).
		SetValidFor(time.Hour)

	return at.ToJWT()
}

func main() {
	http.HandleFunc("/getToken", func(w http.ResponseWriter, r *http.Request) {
		w.write(getJoinToken())
	})
	log.Fatal(http.ListenAndServe(":8080", nil))
}

Run the server:

Copied!
$ source development.env
$ go run server.go

Create a client app that fetches a token from the server we just made, then uses it to connect to a LiveKit room:

React

Swift

Android

Flutter

Rust

JavaScript
