What is Pool Connection ?

---

Connection pooling is a mechanism used in applications to manage connections to data sources like databases. It stores ready-to-use connections, enabling the application to quickly acquire and release connections to the data source.

• pool
  conn_idle : 10 (maximum number of connections in the idle connection pool)
  conn_max : 10 (maximum number of open connections to the database)
  conn_lifetime : 60 (maximum time in minutes for reusing a connection)

JSON WEB TOKEN

• create JSON WEB TOKEN:

auth.NewJWTImpl(signatureKey, dayExpiration).GenerateToken(map[string]interface{})

• validate JSON WEB TOKEN:

auth.NewJWTImpl(signatureKey, dayExpiration).ValidateToken(JWToken)

• parse JSON WEB Token

auth.NewJWTImpl(signatureKey, dayExpiratio).ParseToken(JWToken)

example:

	// create jwt
	dayExpired := 7 // one week
	dataStoreToToken := map[string]interface{}{
		"user":         "John Doe",
		"authenticate": true,
	}
	jwToken, err := NewJWTImpl("superSecret", dayExpired).GenerateToken(dataStoreToToken)
	if err != nil {
		panic(err)
	}
	fmt.Println(jwToken)

	// validate jwt
	valid, _ := NewJWTImpl("superSecret", dayExpired).ValidateToken(jwToken)
	if !valid {
		fmt.Println("token not valid")
	}
	fmt.Println("token valid")

	// parse jwt
	planData, _ := NewJWTImpl("superSecret", dayExpired).ParseToken(jwToken)
	fmt.Println(planData)

Caching

• set key and value cache

	simpleCache := simplecache.NewSimpleCache(simplecache.SimpleCache{
		ExpiredAt: 10, // How long will the data remain stored in the cache before being deleted
		PurgeTime: 30, // How long will the data remain stored in the cache before it is deleted
	})

	cache := simpleCache.Open()
	simpleCache.Set("hello", "world")

• get the value

  value := simpleCache.Get("hello")
  fmt.Println(vaue)

• delete key and value

	simpleCache.Delete("hello")
