Features

Splash page with modal that toggles between a login and signup form

Modal UI component renders either the login or signup form container components

const Modal = ({ modal, closeModal }) => {
  if (!modal) {
    return null;
  }

  let component = null;
  switch (modal) {
    case "login":
      component = <LoginForm id="form" />;
      break;
    case "signup":
      component = <SignupForm id="form" />;
      break;
  }
  return (
    <div className="modal-background" onClick={closeModal}>
      <div className="modal-child" onClick={e => e.stopPropagation()}>
        {component}
      </div>
    </div>
  );
};

Login/signup form container component provides session form component with correct form type, actions, and a button to switch to other form type as props

const mapStateToProps = ({ session, entities: { users }, errors }) => ({
  currentUser: users[session.id],
  formType: "login",
  errors: errors.session,
});

const mapDispatchToProps = (dispatch, ownProps) => ({
  processForm: (user) => dispatch(login(user)),
  demoLogin: () =>
    dispatch(login({ email: "demo@demo.demo", password: "demopassword" })).then(
      () => {
        setTimeout(() => {
          alert("Your demo user session has expired. Please log in again.");
          dispatch(logout());
        }, 600000);
      }
    ),
  closeModal: () => dispatch(closeModal()),
  // Button to change modal to other form type
  otherForm: (
    <button
      className="other-form"
      onClick={() => dispatch(openModal("signup"))}
    >
      Sign Up
    </button>
  ),
  clearErrors: () => dispatch(clearSessionErrors()),
});

Book Reviews

• Logged in users can rate books by selecting a certain number of stars

• A processing animation is shows when reviews are submitted, and then the new review appears at the top of the list

// Book reviews component - called when "Post Review" clicked
handleSubmit(e) {
  e.preventDefault();
  let { loading, ...review } = this.state;
  review.rating = parseInt(review.rating);

  // Show loading animations
  this.setState({
    loading: true
  });
  
  // AJAX POST request
  this.props.submitReview(review).then(
    () => {
      // Refetch book reviews after new review added
      this.props.fetchBook(this.props.bookId).then(
        () => {
          // Reset component state
          this.setState({
            review_text: "",
            rating: undefined,
            book_id: this.props.book.id,
            user_id: this.props.user_id,
            loading: false // Remove loading animation
          });
       });
    },
    err => {
      this.setState({
        loading: false
      });
    }
  );
}
