where Router.events should be used in angular

Question

I want to know the current route of the application, when i checked i got solution where router.events.subscribe is used. But i saw conflicting solution like, some were coding in constructor and some were coding in ngOninit. Where exactly the code router.events.subscribe has to be placed.

Answer 1

I think the best way is to use ngOnInit()

see this question

Mostly we use ngOnInit for all the initialization/declaration and avoid stuff to work in the constructor. The constructor should only be used to initialize class members but shouldn't do actual "work".

So you should use constructor() to setup Dependency Injection and not much else. ngOnInit() is better place to "start" - it's where/when components' bindings are resolved.
