Example 1: how to make react router Link active

const Router = () => (
  <BrowserRouter>
    <div>
      <Nav>
        <NavLink exact={true} activeClassName='is-active' to='/'>Home</NavLink>
        <NavLink activeClassName='is-active' to='/about'>About</NavLink>
      </Nav>

      <Match pattern='/' exactly component={Home} />
      <Match pattern='/about' exactly component={About} />
      <Miss component={NoMatch} />
    </div>
  </BrowserRouter>
)

<NavLink to="/about">About</NavLink>

Example 3: navlink react

<NavLink
  to="/events/123"
  isActive={(match, location) => {
    if (!match) {

    }

    // only consider an event active if its event id is an odd number
    const eventID = parseInt(match.params.eventID);
    return !isNaN(eventID) && eventID % 2 === 1;
  }}
>
