Navigating to the same component with different params + Angular 9

I share example how navigate the same component but with different params.

TS

1. On your constructor, 'type' is name of params on url, and setupComponent is a method.

2. Method setupComponent.

That it is, when you change the params on url, te value on setupComponent changes.
