Navigate relative with Angular 2 Router (Version 3)

Question

How to navigate relative from /questions/123/step1 to /questions/123/step2 within a component using Router without string concatenation and specifying /questions/123/?

I've added an own answer below. Please feel free to suggest a better answer. ;-) I guess there are better approaches.

Answer 1

After doing some more research I came across with

this.router.createUrlTree(['../step2'], {relativeTo: this.activatedRoute});

and

this.router.navigate(['../step2'], {relativeTo: this.activatedRoute});

First approach (Router.createUrlTree API) did not work for me, i.e. nothing happened. Second approach (Router.navigate API) works.

It seems that there were changes in Angular 7.1. There is an answer in another post how to solve it with Angular 7.1. Please refer to https://stackoverflow.com/a/38634440/42659.

Answer 2

First, inject router & ActivatedRoute on constructor

constructor(private route:ActivatedRoute,private router:Router) { }

then use to Click Event:

onEditClick(){
        this.router.navigate(['edit'],{relativeTo:this.route});

You navigate to the expected page.In my scenario, I wanted to go recipe /1 to edit the recipe. http://localhost:4200/recipes/1/edit

Answer 3

Note: the routes are case sensitive so make sure you match the casing across

This worked for me for Angular 8:
From the parent component / page, to navigate to the sub page using typescript:

this.router.navigate(['subPage'], { relativeTo: this.route });

My router in the parent's module looks like this:

const routes: Routes = [
  {
    path: '',
    component: MyPage,
    children: [
      { path: 'subPage', component: subPageComponent}
    ]
  }
];

And on the parent's html page use the following to navigate using a link:

<a [routerLink]="'subPage'">Sub Page Link</a>
<router-outlet></router-outlet>
