Installation

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 github.com/<user>/<repo>

And then install the badger implementation:

go get github.com/gofiber/storage/badger/v2

Examples

Import the storage package.

import "github.com/gofiber/storage/badger/v2"

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,
})

Config

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,
}
