How to set Bootstrap navbar “active” class in Angular 2?

Question

How can I set Bootstrap navbar \"active\" class in Angular 2? I only found Angular 1 way.

When I go to About page, add class=\"active\"

Answer 1

In "@angular/router": "^3.3.1", the difference in the previous version is the bracket in the routerLinkActive

[routerLinkActive]="['active']"

In final release, ng2 will complain so just remove the bracket

routerLinkActive="active"
