angular - Execute base component before using route component for auth -

i have small sample application loads various components based on routes in angular 2 (using typescript).

what i'd try next way auth checking before the actual component belongs route called.

i example create sort of base class , let of component classes extend that. have make sure of components call constructor of base class.

but perhaps there more "angular 2" way achieve same goal?

i haven't found info on matter yet. there way trigger, let's authcomponent class before other component loaded?

check @canactivate annotation:

you can prevent component getting instantiated , reroute them login.
