Connect to Aiven for Valkey™ with Go

Establish a connection to the Aiven for Valkey™ service using Go. This example demonstrates how to connect to Aiven for Valkey from Go using the go-valkey/valkey library, designed to interact with the Valkey protocol.

Variables​

Replace placeholders in the code sample with values from your service overview page:

VariableDescription
SERVICE_URIURI for the Aiven for Valkey service connection

Prerequisites​

Install the valkey-go library using the following command:

go get github.com/valkey-io/valkey-go

Set up and run​

  1. Create a file named main.go and insert the code below, substituting the placeholder with your Aiven for Valkey URI:

    package main

    import (
    	"context"
    	"fmt"

    	"github.com/valkey-io/valkey-go"
    )

    var ctx = context.Background()

    func main() {
    	valkeyURI := "SERVICE_URI"

    	opts, err = valkey.ParseURL(valkeyURI)
    	if err != nil {
    		return panic(err)
    	}

    	client, err := valkey.NewClient(opts)
    	if err != nil {
    		panic(err)
    	}
    	defer client.Close()

    	err = client.Do(ctx, client.B().Set().Key("key").Value("hello world").Nx().Build()).Error()
    	if err != nil {
    		panic(err)
    	}

    	value, err := client.Do(ctx, client.B().Get().Key("key").Build()).ToString()
    	if err != nil {
    		panic(err)
    	}
    	fmt.Println("The value of key is:", value)
    }

    This code creates a key named key with the value hello world without an expiration. It then retrieves this key from the Valkey service and outputs its value.

  2. Run the script using the following command:

    go run main.go

    A successful connection displays:

    The value of key is: hello world
