# Session lifetime timeout and csrf token mismatch

In app/Exceptions/Handler.php replace this:

public function render($request, Exception $e)
{
    if ($e instanceof \Illuminate\Session\TokenMismatchException) {
        return redirect()->back()->withInput()->with('token', csrf_token());
    }

    return parent::render($request, $e);
}

<div>
    <script>
        document.addEventListener('livewire:load', () => {
            setInterval(function(){ window.livewire.emit('alive'); }, 1800000);
        });
    </script>
</div>
