const downloadBtn = document.getElementById('downloadBtn');
const recordedVideo = document.getElementById('recordedVideo');
const status = document.getElementById('status');

// Function to display notifications
function showNotification(title, message) {
 chrome.runtime.sendMessage({
   type: 'show_notification',
   title: title,
   message: message,
   iconUrl: 'icons/icon48.png'
 });
}

// Listen for messages from background script
chrome.runtime.onMessage.addListener((request, sender, sendResponse) => {
 if (request.action === 'start-recording') {
   if (!mediaRecorder || mediaRecorder.state === 'inactive') {
     startRecording();
   } else {
     showNotification('Already Recording', 'A recording is already in progress.');
   }
 } else if (request.action === 'stop-recording') {
   if (mediaRecorder && mediaRecorder.state === 'recording') {
     stopRecording();
   } else {
     showNotification('Not Recording', 'There is no active recording to stop.');
   }
 }
});

// Function to start recording
async function startRecording() {
 try {
   // Request screen capture
   const stream = await navigator.mediaDevices.getDisplayMedia({
     video: {
       mediaSource: 'screen',
       cursor: 'always'
     },
     audio: false // Set to true if audio is required and supported
   });

   // Initialize MediaRecorder
   mediaRecorder = new MediaRecorder(stream, {
     mimeType: 'video/webm; codecs=vp9'
   });

   // Event handler for data availability
   mediaRecorder.ondataavailable = (event) => {
     if (event.data.size > 0) {
       recordedChunks.push(event.data);
     }
   };

   // Event handler for stopping the recording
   mediaRecorder.onstop = () => {
     const blob = new Blob(recordedChunks, { type: 'video/webm' });
     recordedChunks = [];
     const url = URL.createObjectURL(blob);
     recordedVideo.src = url;
     recordedVideo.style.display = 'block';
     downloadBtn.href = url;
     downloadBtn.download = `recording_${new Date().toISOString()}.webm`;
     downloadBtn.disabled = false;
     status.textContent = 'Recording Stopped. You can download the video below.';
     showNotification('Recording Stopped', 'Your screen recording has been saved.');

     // Stop all tracks to release resources
     stream.getTracks().forEach(track => track.stop());
   };

   // Start recording
   mediaRecorder.start();
   console.log('Recording started');
   status.textContent = 'Recording...';
   showNotification('Recording Started', 'Your screen recording has begun.');

   // Update UI
   startBtn.disabled = true;
   stopBtn.disabled = false;
   downloadBtn.disabled = true;
   recordedVideo.style.display = 'none';
   recordedVideo.src = '';

   // Listen for the user stopping the screen sharing
   stream.getVideoTracks()[0].addEventListener('ended', () => {
     if (mediaRecorder.state !== 'inactive') {
       mediaRecorder.stop();
     }
   });
 } catch (err) {
   console.error('Error starting screen capture:', err);
   alert('Could not start screen capture. Please ensure you have granted permissions.');
 }
}

// Function to stop recording
function stopRecording() {
 if (mediaRecorder && mediaRecorder.state === 'recording') {
   mediaRecorder.stop();
   console.log('Recording stopped');
   status.textContent = 'Stopping recording...';

   // Update UI
   startBtn.disabled = false;
   stopBtn.disabled = true;
 }
}

// Handle Start Button Click
startBtn.addEventListener('click', () => {
 if (!mediaRecorder || mediaRecorder.state === 'inactive') {
   startRecording();
 } else {
   showNotification('Already Recording', 'A recording is already in progress.');
 }
});

// Handle Stop Button Click
stopBtn.addEventListener('click', () => {
 stopRecording();
});

// Handle Download Button Click (Optional: Could be redundant as download is handled via href)
downloadBtn.addEventListener('click', () => {
 // The download is handled by setting the href and download attributes
});
```

## Security and Privacy Considerations

When developing and using screen recording extensions, it's essential to prioritize user privacy and security:

- **Inform Users Clearly:**
 - **Transparency:** Clearly state what the extension does and the permissions it requires.
 - **Consent:** Ensure users understand and consent to the data being captured.

- **Handle Data Securely:**
 - **Local Storage:** Store recorded data locally and avoid transmitting it over the internet without explicit user consent.
 - **Data Protection:** Implement measures to protect recorded data from unauthorized access.

- **Respect User Privacy:**
 - **Selective Recording:** Allow users to choose specific screens, windows, or tabs to record, preventing unintended capture of sensitive information.
 - **No Background Recording:** Ensure that the extension does not record in the background without user initiation.

- **Minimize Permissions:**
 - **Least Privilege:** Request only the necessary permissions required for the extension's functionality to enhance user trust.

- **Regular Updates:**
 - **Security Patches:** Keep the extension updated to address any security vulnerabilities promptly.
 - **User Notifications:** Inform users about updates, especially those related to security or privacy enhancements.
