Design of Flask Application to Fetch and Display Top 20 News Articles for a Given Date

HTML Files:

1. index.html: This HTML file serves as the homepage of the application. It presents a user-friendly interface that consists of:

   • A title or header introducing the purpose of the application.
   • A date picker input field for the user to select a date for fetching the news articles.
   • A submit button that triggers the Flask application to fetch and display the news articles for the selected date.

2. news.html: This HTML file is responsible for displaying the fetched news articles. It includes:

   • A heading or title indicating the date for which the news articles are being displayed.
   • A list of the top 20 news articles for the specified date, with each article including a title, a short description, and a link to the full article on the original news website.

Routes:

1. Home Route (/): This route handles the display of the homepage (index.html). When a user accesses the application's root URL (i.e., http://localhost:5000/), this route is triggered, and the index.html file is rendered.

2. Fetch News Route (/fetch_news): This route is responsible for fetching the top 20 news articles for a given date. It accepts a date as a parameter and performs the following tasks:

   • Calls a suitable news API or web scraping tool to fetch the news articles for the specified date.
   • Stores the fetched news articles in a temporary data structure or database (not part of the Flask design).
   • Redirects the user to the news.html file, passing the fetched news articles as a variable.

3. Display News Route (/news): This route handles the rendering of the news.html file. It receives the fetched news articles from the Fetch News route and displays them in a user-friendly format, as described in the news.html section.

Additional Notes:

• The application should incorporate error handling for scenarios such as invalid date inputs or API/web scraping failures.
• The design assumes a basic understanding of HTML and Jinja2 templating for the HTML files.
• The specific implementation details, including the API/web scraping tool selection and data storage mechanism, are left to the developer's discretion.
