HI @balmy spoke !!!
One of the uses of server$ can be to create logger.
You have in mind to build a new Logger('write', '/logger/log.txt', new Date(), 'Register log .Component 1 ').
That every time a component is executed, information can be saved in a log.txt file?

Like something of this type, but that can be saved to a .txt file
