Angular 6 LifeCycle hooks / events are not being called.

If lifecycle hooks of your Angular 6 application are not being called then check whether your functions are using arrow function syntax. I have this issue and after some googling i found the solution.

The issue is that I was using the arrow function syntax (=>) like this:

class MyComponent implements OnInit {
    public ngOnInit = () => {
        console.log("ngOnInit");
    }
}

Apparently that does not work in Angular 6. Using non-arrow function syntax fixes the issue:

class MyComponent implements OnInit {
    public ngOnInit() {
        console.log("ngOnInit");
    }
}
