react router – Redirection after login

by

Wanted to update this thread because I spent a good amount of time digging around on this. In React Router 2.0.x, replaceState is deprecated in favor of replace. See here for details: https://github.com/ReactTraining/react-router/blob/v2.0.0/upgrade-guides/v2.0.0.md#link-to-onenter-and-isactive-use-location-descriptors

The correct way to do this would be something like this:

function requireAuth(nextState, replace) {
  if (!userExists()) {
    replace({
      pathname: '/signin',
      state: { nextPathname: nextState.location.pathname }
    })
  }
}

export const renderRoutes = () => (
  <Router history={browserHistory}>
      <Route path="protectedRoute" component={Protected} onEnter={requireAuth} />
      <Route path="signin" component={SignIn} />
    </Route>
  </Router>
);

Then, in the SignIn component, you can redirect after a successful sign in like this:

signInFunction({params}, (err, res) => {
  // Now in the sign in callback
  if (err)
    alert("Please try again")
  else {
    const location = this.props.location
    if (location.state && location.state.nextPathname) {
      browserHistory.push(location.state.nextPathname)
    } else {
      browserHistory.push("https://stackoverflow.com/")
    }
  }
})
