React Fetch data

Use componentDidMount hook with fetch

class PostsList extends Component {
  constructor(props) {
    super(props);
    this.state = {posts: []};
  }
  componentDidMount() {
    fetch('https://example.com/posts')
      .then(response => response.json())
      .then(data => this.setState({ posts: data.posts }));
      .catch(error => console.log(error));
  }
}

Use Axios library to fetch datas

import axios from 'axios';
componentDidMount() {
  axios.get('/post', {
    params: {ID: 123}
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });
}
