#59886 Por ejemplo no me gusta tener como dices application struct con fuciones de router,servicio o db:
```go
type Application struct { // size=184 (0xb8)
logger *slog.Logger
DBmodel models.DBModelInterface
SystemKeys models.SystemKeys
Stripe StripeService
ServiceUrl string
CloudProject string
}
```
```go
func (app *Application) CheckoutSession(w http.ResponseWriter, r *http.Request)
func (app *Application) CookieAuth(next http.Handler) http.Handler
func (app *Application) EventListener(w http.ResponseWriter, r *http.Request)
func (app *Application) askDB(w http.ResponseWriter, r *http.Request)
func (app *Application) cancelSubcriptions(w http.ResponseWriter, r *http.Request)
func (app *Application) clientError(w http.ResponseWriter, status int)
func (app *Application) confirmaCancel(w http.ResponseWriter, c *models.ConfirmaSmsParams) (val string, err error)
func (app *Application) confirmaSend(w http.ResponseWriter, c *models.ConfirmaSmsParams) (s string, err error)
func (app *Application) deleteSession(w http.ResponseWriter, r *http.Request)
func (app *Application) getCustomer(w http.ResponseWriter, r *http.Request)
func (app *Application) getUserByStripeCustomerID(stripeCustomerID string) (*User, error)
func (app *Application) healthCheck(w http.ResponseWriter, r *http.Request)
func (app *Application) isValidAPIKey(key string) bool
func (app *Application) logRequest(next http.Handler) http.Handler
func (app *Application) notifySubscriptionCanceled(subData stripe.Subscription) error
func (app *Application) recoverPanic(next http.Handler) http.Handler
func (app *Application) redirectHandler(w http.ResponseWriter, r *http.Request)
func (app *Application) routes() http.Handler
func (app *Application) serverError(w http.ResponseWriter, r *http.Request, err error)
func (app *Application) trulyDeleteSession(s string) error
func (app *Application) validateOrigin(next http.Handler) http.Handler```
Y sobre el state es porque paso urls, o variables dentro de Application a otras partes como a StripeApp atraves de Application:
type StripeService struct { // size=80 (0x50)
logger *slog.Logger
ServiceUrl string
TempClients *sync.Map
SessionManager
SubscriptionManager
CustomerManager
}
```
```go
func (app *StripeService) CancelOpenSessions(customerId string) error
func (app *StripeService) CancelSubscription(sub models.SubscriptionParams) (string, error)
func (app *StripeService) CheckActiveSubscription(customerId string, priceId string) (bool, error)
func (app *StripeService) CheckExistingCustomer(user models.SessionParams) (string, error)
func (app *StripeService) CheckoutSessionExpired(s stripe.CheckoutSession, e stripe.Event)
func (app *StripeService) CompletedCheckoutSession(session stripe.CheckoutSession, event stripe.Event)
func (app *StripeService) CreateCheckoutSession(sessionParams models.SessionParams) (*stripe.CheckoutSession, error)
func (app *StripeService) FindOrCreateCustomer(user models.SessionParams) (string, error)
func (app *StripeService) GetCustomer(email string, selectraId string) ([]models.CustomerSubscriptionInfo, error)
func (app *StripeService) GetProductName(subscription *stripe.Subscription) string
func (app *StripeService) createCustomer(user models.SessionParams) (*stripe.Customer, error)
Y no me gusta tener todo asi, nose bien como ordenarlo todo.
SessionManager, SubscriptionManager y CustomerManager, son interfaces... esta es una forma lógica de estructurar codigo?
Dentro de stripe.go tambien llamo a app como StripeService:
func (app *StripeService) CheckActiveSubscription(customerId, priceId string) (bool, error) {
params := &stripe.SubscriptionListParams{
Customer: stripe.String(customerId),
Status: stripe.String("active"),
}
...
Con esto me refiero a que tengo poca referencia de como hacer bien o mal las cosas, simplemente las hago pero tengo poca idea de cleancode y como hacer codigo legible y entendible por otros...
Y sobre testing, como testeas un servicio externo y apis externas?? Si tu func espera la busqueda de un cliente, como testeas eso??
