How can I add a progress bar to show the download status in the YouTube Video Downloader template?

To add a progress bar, you can use JavaScript to update the UI based on the download progress. Here's a basic example of how you might implement this:

``javascript // Add this to home.js function updateProgressBar(progress) { const progressBar = document.getElementById('download-progress'); progressBar.style.width =${progress}%; progressBar.textContent =${progress}%`; }

// In your download function fetch('/download', { method: 'POST', body: JSON.stringify({ url: videoUrl }) }) .then(response => { const reader = response.body.getReader(); const contentLength = +response.headers.get('Content-Length'); let receivedLength = 0;

   return new ReadableStream({
     start(controller) {
       function push() {
         reader.read().then(({ done, value }) => {
           if (done) {
             controller.close();
             return;
           }
           receivedLength += value.length;
           const progress = Math.round((receivedLength / contentLength) * 100);
           updateProgressBar(progress);
           controller.enqueue(value);
           push();
         });
       }
       push();
     }
   });
 })
 .then(stream => new Response(stream))
 .then(response => response.blob())
 .then(blob => {
   // Handle the completed download
 });

```

This code assumes you've added a progress bar element to your HTML with the id 'download-progress'.

How can I implement video format selection in the YouTube Video Downloader template?

To implement video format selection, you'll need to modify both the frontend and backend of the YouTube Video Downloader template. Here's a basic example:

In the HTML (home.html): html <select id="format-select"> <option value="mp4">MP4</option> <option value="webm">WebM</option> <option value="audio">Audio Only (MP3)</option> </select>

In the JavaScript (home.js): ```javascript const formatSelect = document.getElementById('format-select');

function downloadVideo() { const videoUrl = document.getElementById('video-url').value; const format = formatSelect.value;

 fetch('/download', {
   method: 'POST',
   headers: { 'Content-Type': 'application/json' },
   body: JSON.stringify({ url: videoUrl, format: format })
 })
 .then(response => response.blob())
 .then(blob => {
   // Handle the download
 });

} ```

In the Python backend (routes.py): ```python from flask import request, send_file import yt_dlp

@app.route("/download", methods=['POST']) def download_video(): data = request.json url = data['url'] format = data['format']

   ydl_opts = {
       'format': 'bestaudio/best' if format == 'audio' else f'best[ext={format}]',
       'postprocessors': [{
           'key': 'FFmpegExtractAudio',
           'preferredcodec': 'mp3',
           'preferredquality': '192',
       }] if format == 'audio' else [],
   }

   with yt_dlp.YoutubeDL(ydl_opts) as ydl:
       info = ydl.extract_info(url, download=False)
       filename = ydl.prepare_filename(info)
       ydl.download([url])

   return send_file(filename, as_attachment=True)

```

This implementation allows users to select their preferred format before downloading, enhancing the functionality of the YouTube Video Downloader template.
