Echo SCS Session Middleware

All credit must go to alexedwards for his great package scs

Features (As per SCS)

Automatic loading and saving of session data via middleware.
Choice of server-side session stores including PostgreSQL, MySQL, Redis, BadgerDB and BoltDB. Custom session stores are also supported.
Supports multiple sessions per request, 'flash' messages, session token regeneration, idle and absolute session timeouts, and 'remember me' functionality.
Easy to extend and customize. Communicate session tokens to/from clients in HTTP headers or request/response bodies.
Efficient design. Smaller, faster and uses less memory than gorilla/sessions.

package main

import (

	"time"

	"github.com/alexedwards/scs/v2"
	"github.com/labstack/echo/v4"
	"github.com/spazzymoto/echo-scs-session"
)

var sessionManager *scs.SessionManager

func main() {
	// Initialize a new session manager and configure the session lifetime.
	sessionManager = scs.New()
	sessionManager.Lifetime = 24 * time.Hour

	e := echo.New()

	// Use the LoadAndSave() middleware.
	e.Use(session.LoadAndSave(sessionManager))

	e.GET("/put", putHandler)
	e.GET("/get", getHandler)

	e.Logger.Fatal(e.Start(":4000"))
}

func putHandler(c echo.Context) error {
	// Store a new key and value in the session data.
	sessionManager.Put(c.Request().Context(), "message", "Hello from a session!")

	return c.String(http.StatusOK, "")
}

func getHandler(c echo.Context) error {
	// Use the GetString helper to retrieve the string value associated with a
	// key. The zero value is returned if the key does not exist.
	msg := sessionManager.GetString(c.Request().Context(), "message")

	return c.String(http.StatusOK, msg)
