Session middleware for Fiber.

:::note This middleware uses our Storage package to support various databases through a single interface. The default configuration for this middleware saves data to memory, see the examples below for other databases. :::

Signatures

func New(config ...Config) *Store
func (s *Store) RegisterType(i interface{})
func (s *Store) Get(c *fiber.Ctx) (*Session, error)
func (s *Store) Reset() error

func (s *Session) Get(key string) interface{}
func (s *Session) Set(key string, val interface{})
func (s *Session) Delete(key string)
func (s *Session) Destroy() error
func (s *Session) Regenerate() error
func (s *Session) Save() error
func (s *Session) Fresh() bool
func (s *Session) ID() string
func (s *Session) Keys() []string

:::caution Storing interface{} values are limited to built-ins Go types. :::

Examples

Import the middleware package that is part of the Fiber web framework

import (
  "github.com/gofiber/fiber/v2"
  "github.com/gofiber/fiber/v2/middleware/session"
)

Then create a Fiber app with app := fiber.New().

Default Configuration

// This stores all of your app's sessions
// Default middleware config
store := session.New()

// This panic will be caught by the middleware
app.Get("/", func(c *fiber.Ctx) error {
    // Get session from storage
    sess, err := store.Get(c)
    if err != nil {
        panic(err)
    }

    // Get value
    name := sess.Get("name")

    // Set key/value
    sess.Set("name", "john")

    // Get all Keys
    keys := sess.Keys()

    // Delete key
    sess.Delete("name")

    // Destroy session
    if err := sess.Destroy(); err != nil {
        panic(err)
    }

    // Save session
    if err := sess.Save(); err != nil {
		panic(err)
	}

	return c.SendString(fmt.Sprintf("Welcome %v", name))
})

Custom Storage/Database

You can use any storage from our storage package.

storage := sqlite3.New() // From github.com/gofiber/storage/sqlite3
store := session.New(session.Config{
	Storage: storage,
})

To use the store, see the above example.

Config

// Config defines the config for middleware.
type Config struct {
	// Allowed session duration
	// Optional. Default value 24 * time.Hour
	Expiration time.Duration

	// Storage interface to store the session data
	// Optional. Default value memory.New()
	Storage fiber.Storage

	// Name of the session cookie. This cookie will store session key.
	// Optional. Default value "session_id".
	CookieName string

	// Domain of the cookie.
	// Optional. Default value "".
	CookieDomain string

	// Path of the cookie.
	// Optional. Default value "".
	CookiePath string

	// Indicates if cookie is secure.
	// Optional. Default value false.
	CookieSecure bool

	// Indicates if cookie is HTTP only.
	// Optional. Default value false.
	CookieHTTPOnly bool

	// Sets the cookie SameSite attribute.
	// Optional. Default value "Lax".
	CookieSameSite string

	// KeyGenerator generates the session key.
	// Optional. Default value utils.UUID
	KeyGenerator func() string
}

Default Config

var ConfigDefault = Config{
	Expiration:   24 * time.Hour,
	CookieName:   "session_id",
	KeyGenerator: utils.UUID,
}
