Logging Extension Improvements

Suggestion

• should include a global logger for use outside of the application so that we can make sure to catch and log exceptions for problems with the application boot-up. console.log won't cut it here as logs still need to be json structured and sent to an external logging service.

• Http Access Logs should be json structured rather than putting the log in string format.

Use Cases

I'm deploying my application to Google App Engine and structure logs for both normal logs as well as error logs is an absolute must to correctly parse any problems.

Examples

Logging should be tightly integrated with the application. A global logger should be setup and passed into the application as part of the application initialisation (I suggest simply choosing winston by convention). The global logger can then be accessed by the migration scripts, and can also be used inside the main function for circumstances where the application doesn't boot.

The HTTP Access Logger should be a middleware that takes a callback with some for such as:

LogCallbackFn(logger: WinstonLogger, req: Request, res: Response)

This way the logger call can be customised.

Acceptance criteria

TBD - will be filled by the team.

Inizia individuando il percorso di inizializzazione dell’applicazione, gli script di migrazione, la funzione main e il middleware di logging degli accessi HTTP. Chiarisci con il team i criteri di accettazione mancanti, quindi definisci il completamento in modo che sia disponibile un logger strutturato globale durante l’avvio e le migrazioni, oltre a log di accesso HTTP JSON personalizzabili adatti ai servizi esterni.
