id: bbolt title: Bbolt

A Bbolt storage driver using etcd-io/bbolt. Bolt is a pure Go key/value store inspired by Howard Chu's LMDB project. The goal of the project is to provide a simple, fast, and reliable database for projects that don't require a full database server such as Postgres or MySQL.

Installation

Bbolt 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 s3 implementation:

go get github.com/gofiber/storage/bbolt

Examples

Import the storage package.

import "github.com/gofiber/storage/bbolt"

You can use the following possibilities to create a storage:

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

// Initialize custom config
store := bbolt.New(bbolt.Config{
	Database: "my_database.db",
	Bucket:   "my-bucket",
	Reset:    false,
})

Config

// Config defines the config for storage.
type Config struct {
	// Database path
	//
	// Optional. Default is "fiber.db"
	Database string

	// Bbolt bucket name
	//
	// Optional. Default is "fiber_storage"
	Bucket string

	// Timeout is the amount of time to wait to obtain a file lock.
	// Only available on Darwin and Linux.
	//
	// Optional. Default is 60 * time.Second.
	Timeout time.Duration

	// Open database in read-only mode.
	//
	// Optional. Default is false
	ReadOnly bool

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

Default Config

// ConfigDefault is the default config
var ConfigDefault = Config{
	Database: "fiber.db",
	Bucket:   "fiber_storage",
	Timeout:  60 * time.Second,
	ReadOnly: false,
	Reset:    false,
}
