I have a UserComponent and I want it to display a user based on a userId
querystring param like this: localhost:3000/users?userId=1
Otherwise, if the url does not have a userId qs param I simply want to
display all users: localhost:3000/users
In my code below the first part of the code is still getting run even
though there is no qs param:
ngOnInit(): void {
// subscribe to router event
this.subscription = this.activatedRoute.queryParams.subscribe(
(param: any) => {
let userId = param['userId'];
//console.log(userId);
this.getUser(userId);
});
this.getUsers();
}
The first part of the code ends up calling the rest svc for getUser with an
undefined userId: http://localhost:4000/users/undefined
How do I need to restructure this code in order to accomodate this scenario?
