onEnter not called in React-Router

Ok, I'm fed up trying.
The onEnter method doesn't work. Any idea why is that?

// Authentication "before" filter
function requireAuth(nextState, replace){
  console.log("called"); // => Is not triggered at all 
  if (!isLoggedIn()) {
      pathname: '/front'

// Render the app
  <Provider store={store}>
      <Router history={history}>
            <Route path="/front" component={Front} />
            <Route path="/home" component={Home} onEnter={requireAuth} />
            <Route exact path="/" component={Home} onEnter={requireAuth} />
            <Route path="*" component={NoMatch} />


The method is executed when I call onEnter={requireAuth()}, but obviously that is not the purpose, and I also won't get the desired parameters.



onEnter no longer exists on react-router-4. You should use <Route render={ ... } /> to get your desired functionality. I believe Redirect example has your specific scenario. I modified it below to match yours.

<Route exact path="/home" render={() => (
  isLoggedIn() ? (
    <Redirect to="/front"/>
  ) : (
    <Home />

From react-router-v4 onEnter, onUpdate, and onLeave is removed, according the documentation on migrating from v2/v3 to v4:

on* properties
React Router v3 provides onEnter, onUpdate, and onLeave methods. These were essentially recreating React's lifecycle methods.

With v4, you should use the lifecycle methods of the component rendered by a <Route>. Instead of onEnter, you would use componentDidMount or componentWillMount. Where you would use onUpdate, you can use componentDidUpdate or componentWillUpdate (or possibly componentWillReceiveProps). onLeave can be replaced with componentWillUnmount.
