How to display all stories from the Hacker News API on my React app when loading the website?

I've made a copy of the Hacker News Search but I can't display all stories from the API when I get on my website. No stories appear at all. I have to type something on the searchbar to display them all.

I've fetched the data with axios, I console.log the collection and it appears that the data has been successfully fetched because I can see the collection on my console.

The github repo : https://github.com/vnsteven/hacker-news-react

The website : https://vnsteven.github.io/hacker-news-react/

The beginning of my App.js file (src/containers/App.js):

import React, { Component } from 'react';

import Navbar from '../components/Navbar/Navbar';
import Footer from '../components/Footer/Footer';
import Items from '../components/Items/Items';
import './App.css';
import axios from './axios-hn.js';

class App extends Component {
  state = {
    list: [],
    initialList: [],
    favoriteList: [],
    count: 0,
    favoriteCount: 0
  };

  async componentDidMount() {
    try {
      const fetchingData = await axios.get('topstories.json');
      const itemIds = await fetchingData.data;
      const list = [];
      itemIds.forEach((id) => {
        axios.get(`item/${id}.json`).then((res) =>
          list.push({
            id: res.data.id,
            title: res.data.title,
            score: res.data.score,
            url: res.data.url,
            author: res.data.by
          })
        );
      });
      this.setState({ initialList: list });
    } catch (err) {
      console.error(err);
    }
  }

Here is an example of how you can use the "HackerNews API":

First, the TopStories endpoint returns a list of post ids. You then need to resolve each id into its own post. To simplify that, you can take advantage of the Promise.all API. This method resolves when all the promises provided in an input array, resolve themselves.

I am also using "React Hooks" to handle state changes. Take a look at how to handle state using useState and useEffect hooks.

Anyways, here is the code example:
