react-transition-group Миграция с версии 1 на 4.3.0 пример

В моем случае было:

import React from 'react';
import { connect } from 'react-redux';
import { CSSTransitionGroup } from 'react-transition-group';
import { allSelector } from '../../actions/notifications';
import Notification from './notification';
import '../../../../css/app.css'

class Notifications extends React.Component {
  render() {
    return (
      <CSSTransitionGroup
        component="div"
        className="notifications"
        transitionName="notification-animation"
        transitionEnterTimeout={150}
        transitionLeaveTimeout={50}>
        {this.props.notifications.map(notification => (
          <Notification
            notification={notification}
            key={notification.id}
            delay={5000}
          />
        ))}
      </CSSTransitionGroup>
    );
  }
}


const mapStateToProps = state => ({
  notifications: allSelector(state)
});

export default connect(mapStateToProps)(Notifications);

стало:

import React from 'react';
import { connect } from 'react-redux';
import { TransitionGroup, CSSTransition } from 'react-transition-group';
import { allSelector } from '../../actions/notifications';
import Notification from './notification';
import '../../../../css/app.css'

class Notifications extends React.Component {
  render() {
    return (
      <div className="notifications">
        <TransitionGroup>
          {this.props.notifications.map(notification => (
            <CSSTransition
              key={notification.id}
              component="div"
              className="notifications"
              classNames="notification-animation"
              timeout={{ enter: 150, exit: 50 }}
            >
              <Notification
                notification={notification}
                delay={5000}
              />
            </CSSTransition>
          ))}
        </TransitionGroup>
      </div>
    );
  }
}

const mapStateToProps = state => ({
  notifications: allSelector(state)
});

export default connect(mapStateToProps)(Notifications);
