The Unlaunch Go SDK provides a Go API to access Unlaunch feature flags and other features. Using the SDK, you can easily build Java applications that can evaluate feature flags, dynamic configurations, and more.
- To create feature flags to use with Java SDK, login to your Unlaunch Console at https://app.unlaunch.io
- Official Guide
- Documentation
- Example Project
Here is a simple example.
Run go get github.com/unlaunch/go-sdk add it to your go.mod file.
package main
import (
"fmt"
"time"
"github.com/unlaunch/go-sdk/unlaunchio/client"
)
func main() {
config := client.DefaultConfig()
factory, err := client.NewUnlaunchClientFactory("YOUR_SERVER_KEY", config)
if err != nil {
fmt.Printf("Error initializing Unlaunch client %s\n", err)
return
}
unlaunchClient := factory.Client()
if err = unlaunchClient.AwaitUntilReady(3 * time.Second); err != nil {
fmt.Printf("Unlaunch Client wasn't ready %s\n", err)
}
variation := unlaunchClient.Variation("FLAG_KEY", "USER_ID_123", nil)
if variation == "on" {
// show feature
} else {
// don't show feature
}
}You can start the SDK in offline mode for testing purposes. In offline mode, flags aren't downloaded from the server and no data is sent. All calls to Variation or its variants will return control. Read more in the official guide.
To set offline mode :
config := client.DefaultConfig()
config.OfflineMode = true
To run all tests
go test ./...Create a new tag on GitHub in the following format vx.y.z e.g. v0.0.1
