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"
)

After you initiate your Fiber app, you can use the following possibilities:

// Default middleware config
store := session.New()

// This panic will be catch 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")

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

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

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

	return fmt.Fprintf(ctx, "Welcome %v", name)
})
