If you’re adding navlinks with react router because you want to set the active class you might find that it doesn’t work. These are the steps I had to take to make this work.
// set the exact property on the route
<Route path={"/"} exact={true} component={SharingLinks} />
// but you also need to add exact={true} to your NavLink from react-router!
<NavLink
to={"/"}
exact={true}
activeClassName="active-menu-item"
>
Sharing Link
</NavLink>
