Send data through routing paths in Angular

Question

Is there anyway to send data as parameter with router.navigate? I mean, something like this example, as you can see the route has a data parameter, but doing this it's not working:

this.router.navigate(["heroes"], {some-data: "othrData"})

because some-data is not a valid parameter. How can I do that? I don't want to send the parameter with queryParams.

Answer 1

There is a lot of confusion on this topic because there are so many different ways to do it.

Here are the appropriate types used in the following screen shots:

private route: ActivatedRoute
private router: Router

1) Required Routing Parameters:

2) Route Optional Parameters:

3) Route Query Parameters:

4) You can use a service to pass data from one component to another without using route parameters at all.
