Badger 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 badger implementation:

go get


Import the storage package.

import ""

You can use the following possibilities to create a storage:

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

// Initialize custom config
store := badger.New(badger.Config{
Database: "./fiber.badger",
Reset: false,
GCInterval: 10 * time.Second,


type Config struct {
// Database name
// Optional. Default is "./fiber.badger"
Database string

// Reset clears any existing keys in existing Table
// Optional. Default is false
Reset bool

// Time before deleting expired keys
// Optional. Default is 10 * time.Second
GCInterval time.Duration

// BadgerOptions is a way to set options in badger
// Optional. Default is badger.DefaultOptions("./fiber.badger")
BadgerOptions badger.Options

// Logger is the default logger used by badger
// Optional. Default is nil
Logger badger.Logger

// UseLogger define if any logger will be used
// Optional. Default is false
UseLogger bool

Default Config

var ConfigDefault = Config{
Database: "./fiber.badger",
Reset: false,
GCInterval: 10 * time.Second,
BadgerOptions: badger.DefaultOptions("./fiber.badger").WithLogger(nil),
Logger: nil,
UseLogger: false,
