Debug Console

``` ### **Step 2: Add the Debugging Logic to `app.js`** Next, we need to tell your JavaScript to send messages and errors to this new on-screen console. 1. Open your `scripts/app.js` file. 2. **At the very top of the file**, paste the following code. This function will be our new logger. ```javascript // scripts/app.js // --- On-Screen Debugger --- function logToScreen(message) { const logContainer = document.getElementById('debug-log'); if (logContainer) { // Convert non-string messages to a readable string format if (typeof message !== 'string') { message = JSON.stringify(message, null, 2); } logContainer.innerHTML += `
> ${message}
`; // Auto-scroll to the bottom logContainer.parentElement.scrollTop = logContainer.parentElement.scrollHeight; } } // Redirect all console errors to our on-screen logger window.onerror = function(message, source, lineno, colno, error) { logToScreen(`ERROR: ${message} at ${source.split('/').pop()}:${lineno}`); return true; // Prevents the error from stopping script execution in some browsers }; // --- End On-Screen Debugger --- // --- Module Imports --- import { initUI } from './ui.js'; import { initChat } from './chat.js'; import { initVideo } from './video.js'; // --- Main App Initialization --- document.addEventListener('DOMContentLoaded', () => { logToScreen("DOM fully loaded. Initializing modules..."); // Make the logger globally available so other modules can use it window.logToScreen = logToScreen; try { initUI(); logToScreen("UI module initialized successfully."); initChat(); logToscreen("Chat module initialized successfully."); initVideo(); logToScreen("Video module initialized successfully."); } catch(e) { logToScreen(`A critical error occurred during initialization: ${e.message}`); } logToScreen("Application setup complete."); });
