Install the package

  • If you are using the standard Go modules system, import the SDK packages in your code and go build will automatically download them. The SDK and its dependencies are modules.

  • Alternatively, you can run the following command:
Shell
go get github.com/launchdarkly/go-server-sdk/v7

Initialize the SDK

Go SDK initialization
package main
import (
	"fmt"
	"os"
	"time"
	ld "github.com/launchdarkly/go-server-sdk/v7"
)
func main() {
	// This is your LaunchDarkly SDK key.
	// Never hardcode your SDK key in production.
	ldClient, _ := ld.MakeClient("YOUR_SDK_KEY", 5*time.Second)
	if ldClient.Initialized() {
		fmt.Printf("SDK successfully initialized!")
	} else {
		fmt.Printf("SDK failed to initialize")
		os.Exit(1)
	}
	// For onboarding purposes only we flush events as soon as
	// possible so we quickly detect your connection.
	// You don't have to do this in practice because events are automatically flushed.
	ldClient.Flush()
}

You can find your server-side SDK keys, mobile keys, and client-side ID on the SDK keys page under Settings.
