import React, { Component } from 'react';

class ListComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      loading: true,
      data: []
    };
  }

  componentDidMount() {
    fetch('https://api.example.com/list')
      .then(response => response.json())
      .then(data => {
        this.setState({
          loading: false,
          data: data
        });
      })
      .catch(error => {
        console.error('Error:', error);
      });
  }

  render() {
    const { loading, data } = this.state;

    if (loading) {
      return <div>Loading...</div>;
    }

    return (
      <ul>
        {data.map(item => (
          <li key={item.id}>{item.name}</li>
        ))}
      </ul>
    );
  }
}

export default ListComponent;
