Momento Client Library for Go

Momento Cache is a fast, simple, pay-as-you-go caching solution without any of the operational overhead required by traditional caching solutions. This repo contains the source code for the Momento client library for Go.

To get started with Momento you will need a Momento Auth Token. You can get one from the Momento Console.

Usage

Checkout our examples directory for complete examples of how to use the SDK.

Here is a quickstart you can use in your own project:

package main

import (
	"context"
	"log"
	"time"

	"github.com/google/uuid"
	"github.com/momentohq/client-sdk-go/auth"
	"github.com/momentohq/client-sdk-go/config"
	"github.com/momentohq/client-sdk-go/config/logger"
	"github.com/momentohq/client-sdk-go/momento"
	"github.com/momentohq/client-sdk-go/responses"
)

func main() {
	context := context.Background()
	configuration := config.LaptopLatestWithLogger(logger.NewNoopMomentoLoggerFactory()).WithClientTimeout(15 * time.Second)
	credentialProvider, err := auth.NewEnvMomentoTokenProvider("MOMENTO_API_KEY")
	if err != nil {
		panic(err)
	}
	defaultTtl := time.Duration(9999)

	client, err := momento.NewCacheClient(configuration, credentialProvider, defaultTtl)
	if err != nil {
		panic(err)
	}

	key := uuid.NewString()
	value := uuid.NewString()
	log.Printf("Setting key: %s, value: %s\n", key, value)
	_, _ = client.Set(context, &momento.SetRequest{
		CacheName: "cache-name",
		Key:       momento.String(key),
		Value:     momento.String(value),
		Ttl:       time.Duration(9999),
	})

	if err != nil {
		panic(err)
	}

	resp, err := client.Get(context, &momento.GetRequest{
		CacheName: "cache-name",
		Key:       momento.String(key),
	})
	if err != nil {
		panic(err)
	}

	switch r := resp.(type) {
	case *responses.GetHit:
		log.Printf("Lookup resulted in cache HIT. value=%s\n", r.ValueString())
	case *responses.GetMiss:
		log.Printf("Look up did not find a value key=%s", key)
	}
}
