NATS Key/Value Store driver is tested on the 2 last Go versions with support for modules. So make sure to initialize one first if you didn't do that yet:

go mod init<user>/<repo>

And then install the nats implementation:

go get


Import the storage package.

import ""

You can use the following possibilities to create a storage:

// Initialize default config
store := nats.New()

// Initialize custom config
store := nats.New(Config{
URLs: "nats://",
NatsOptions: []nats.Option{
// Enable TLS by specifying RootCAs
KeyValueConfig: jetstream.KeyValueConfig{
Bucket: "test",
Storage: jetstream.MemoryStorage,


type Config struct {
// Nats URLs, default "nats://". Can be comma separated list for multiple servers
URLs string
// Nats connection options. See nats_test.go for an example of how to use this.
NatsOptions []nats.Option
// Nats connection name
ClientName string
// Nats context
Context context.Context
// Nats key value config
KeyValueConfig jetstream.KeyValueConfig
// Logger. Using Fiber AllLogger interface for adapting the various log libraries.
Logger log.AllLogger
// Use the Logger for nats events, default: false
Verbose bool
// Wait for connection to be established, default: 100ms
WaitForConnection time.Duration

Default Config

var ConfigDefault = Config{
URLs: nats.DefaultURL,
Context: context.Background(),
ClientName: "fiber_storage",
KeyValueConfig: jetstream.KeyValueConfig{
Bucket: "fiber_storage",
WaitForConnection: 100 * time.Millisecond,
