Connect Redux to the Messages App --help

Tell us what’s happening:

I keep getting this error

The Presentational component should receive messages from the Redux store as a prop.

The Presentational component should receive the submitMessage action creator as a prop.


// Redux:
const ADD = 'ADD';

const addMessage = (message) => {
  return {
    type: ADD,
    message: message
  }
};

const messageReducer = (state = [], action) => {
  switch (action.type) {
    case ADD:
      return [
        ...state,
        action.message
      ];
    default:
      return state;
  }
};

const store = Redux.createStore(messageReducer);

// React:
class Presentational extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      input: '',
      messages: []
    }
    this.handleChange = this.handleChange.bind(this);
    this.submitMessage = this.submitMessage.bind(this);
  }
  handleChange(event) {
    this.setState({
      input: event.target.value
    });
  }
  submitMessage() {
    const currentMessage = this.state.input;
    this.setState({
      input: '',
      messages: this.state.messages.concat(currentMessage)
    });
  }
  render() {
    return (
      <div>
        <h2>Type in a new Message:</h2>
        <input
          value={this.state.input}
          onChange={this.handleChange}/><br/>
        <button onClick={this.submitMessage}>Submit</button>
        <ul>
          {this.state.messages.map( (message, idx) => {
              return (
                 <li key={idx}>{message}</li>
              )
            })
          }
        </ul>
      </div>
    );
  }
};

// React-Redux:
const mapStateToProps = (state) => {
  return { messages: state }
};

const mapDispatchToProps = (dispatch) => {
  return {
    submitNewMessage: (newMessage) => {
       dispatch(addMessage(newMessage))
    }
  }
};

const Provider = ReactRedux.Provider;
const connect = ReactRedux.connect;

// define the Container component here:
const Container = connect(mapStateToProps, mapDispatchToProps)(Presentational)

class AppWrapper extends React.Component {
  constructor(props) {
    super(props);
  }
  render() {
    // complete the return statement:
    return (
      <Presentational store={store}> 
        {Container}
      </Presentational>
    );
  }
};

Link to the challenge:

This block of code is giving you an error.

      <Presentational store={store}> 
        {Container}
      </Presentational>

Make sure you are wrapping around Container component with <Provider> and not <Presentational />

Also the correct way to wrap a component is not with curly brackets but regular brackets.

<Container />
