Create native Intel Mac app for Lovable.dev with enhanced UI and CI/CD

[Copilot]

Built an Electron-based macOS desktop application that wraps lovable.dev with enhanced visual design, native platform integration, and automated CI/CD pipelines.

Implementation

Core Application

• Electron main process with webview integration for lovable.dev
• Context isolation and CSP for security (sandbox disabled for webview requirement)
• Hidden inset title bar with draggable navigation region for native macOS feel

Enhanced UI Components

• Animated loading screen with gradient logo, pulse effects, and staggered dot spinner
• Navigation bar with back/forward/refresh/home controls and glassmorphism backdrop
• Status bar with animated connection indicator
• Purple-to-pink gradient theme (#8B5CF6 → #EC4899) on dark navy background

Build Configuration

• Electron Builder targeting Intel x64 architecture
• App bundle and DMG installer build scripts
• Icon assets and proper macOS categorization

CI/CD Workflows

• Build and Release workflow: Automatically builds the app on every push and creates GitHub releases when version tags are pushed
• CI workflow: Validates code quality, JavaScript syntax, package.json format, and project structure on all pushes and pull requests
• Workflows run on macOS latest with Node.js 20
• Build artifacts (.app, .dmg, .zip) available for download with 7-day retention

Key Technical Decisions

Webview over BrowserView: Enables full navigation control and simpler state management
Inline scripts: Required for webview event handlers; CSP relaxed for local content only
Backdrop filter with fallbacks: Enhanced glassmorphism for macOS with solid color fallback

// Navigation integration with webview
webview.addEventListener('did-navigate', () => {
  backBtn.disabled = !webview.canGoBack();
  forwardBtn.disabled = !webview.canGoForward();
});

Note

Adds a native Electron macOS app that wraps https://lovable.dev/, plus packaging and automation.

• Core app: main.js, index.html, styles.css, preload.js with webview navigation (back/forward/refresh/home), loading screen, status bar, CSP, and context isolation (sandbox off for webviewTag)
• Packaging: package.json with electron-builder config (Mac x64), build scripts (build, build-dmg), and assets (assets/icon.svg)
• CI/CD: GitHub Actions workflows build.yml (build artifacts, tag-based releases) and ci.yml (syntax/structure/style checks); docs at .github/workflows/README.md
• Repo updates: README.md, QUICK_START.md, UI_DESIGN.md, VISUAL_PREVIEW.md, and .gitignore for Node/Electron/build outputs

Created GitHub Actions workflows in commit 8441c95:

Build and Release (.github/workflows/build.yml)

• Builds the app on pushes to main/copilot branches
• Creates GitHub releases when version tags are pushed
• Uploads artifacts (.app, .dmg, .zip files)
• Runs on macOS latest with Node.js 20

CI (.github/workflows/ci.yml)

• Validates JavaScript syntax (main.js, preload.js)
• Checks package.json format
• Verifies project structure and required files
• Validates HTML/CSS features
• Runs on every push and pull request

To create a release:

git tag v1.0.0
git push origin v1.0.0

See .github/workflows/README.md for full documentation.

Build references missing icon.png file

The electron-builder configuration specifies "icon": "assets/icon.png" but only assets/icon.svg exists in the repository. This mismatch will cause the macOS build to fail or produce an application bundle without the intended custom icon. The CI/CD workflow that runs npm run build and npm run build-dmg will be affected.

 

[cursor]

External link handler doesn't apply to webview content

The setWindowOpenHandler is set on mainWindow.webContents, but the lovable.dev content is loaded inside a <webview> tag which has its own separate webContents. Links with target="_blank" or window.open() calls from within the webview will not trigger this handler. The webview needs its own new-window event listener in index.html to properly open external links in the default browser.

The example badge URLs contain 'sumitduster-iMac' which appears to be a personal machine identifier. These should be updated to reflect the actual repository owner's GitHub username or organization name for the badges to work correctly.

Suggested change

	Add these to your README.md:

The navigation buttons lack proper accessibility attributes. Consider adding aria-label attributes to provide better descriptions for screen readers, since the buttons only contain SVG icons without visible text labels. For example, aria-label="Navigate back" would be more descriptive than just title="Go back".

[Copilot]

The workflow uses 'npm ci' which requires a package-lock.json file, but package-lock.json is listed in .gitignore. This will cause the release workflow to fail. Either remove package-lock.json from .gitignore and commit it to the repository, or change 'npm ci' to 'npm install' in the workflow files.

[Copilot]

The user-select: none property is applied to the entire body, making all text in the application non-selectable. This creates a poor user experience, as users cannot select and copy text from the lovable.dev website content loaded in the webview. Consider removing this property or applying it more selectively only to UI chrome elements like the navigation bar.

Suggested change

	-webkit-user-select: none;
	user-select: none;

[Copilot]

The Content Security Policy (CSP) allows 'unsafe-inline' for scripts, which undermines the security benefits of CSP. While the comment mentions this is for inline scripts in a local Electron app, the inline scripts in this file (lines 102-154) could be moved to a separate JavaScript file and loaded via script src. This would allow removing 'unsafe-inline' from script-src and improve security posture.

[Copilot]

The workflow uses 'npm ci' which requires a package-lock.json file, but package-lock.json is listed in .gitignore. This will cause the build workflow to fail when trying to install dependencies. Either remove package-lock.json from .gitignore and commit it to the repository, or change 'npm ci' to 'npm install' in the workflow files.

[Copilot]

The loading screen timeout is hardcoded to 2000ms (2 seconds), but this doesn't account for whether the webview has actually finished loading lovable.dev. If the network is slow or the site takes longer to load, users will see a black screen after the loading screen disappears. Consider listening to the webview's 'did-finish-load' or 'dom-ready' event instead to ensure the content is loaded before hiding the loading screen.

Suggested change

	// Show loading screen initially
	setTimeout(() => {
	loadingScreen.classList.add('fade-out');
	setTimeout(() => {
	loadingScreen.style.display = 'none';
	}, 500);
	}, 2000);
	// Wait for webview to be ready
	webview.addEventListener('dom-ready', () => {
	console.log('Lovable webview loaded');
	// Helper to hide the loading screen once the webview is ready
	let loadingScreenHidden = false;
	function hideLoadingScreen() {
	if (loadingScreenHidden) return;
	loadingScreenHidden = true;
	loadingScreen.classList.add('fade-out');
	setTimeout(() => {
	loadingScreen.style.display = 'none';
	}, 500);
	}
	// Wait for webview to be ready before hiding the loading screen
	webview.addEventListener('dom-ready', () => {
	console.log('Lovable webview loaded');
	hideLoadingScreen();

The Electron version specified is ^28.0.0, which allows any version from 28.0.0 up to but not including 29.0.0. While this is common practice, Electron major versions can introduce breaking changes. For a desktop application that needs stability, consider using a more restrictive version constraint (e.g., ~28.0.0 for patch updates only, or pinning to a specific version) to avoid unexpected breaking changes from minor version updates.

Suggested change

	"electron": "^28.0.0",
	"electron": "~28.0.0",

[Copilot]

The console.log statement outputs a message when the webview loads, but there's no user-facing feedback or error handling if the webview fails to load. Consider adding error event listeners (e.g., 'did-fail-load') to handle and display connection errors to users, rather than just logging to the console.

Suggested change

	// Handle webview load failures with user-facing feedback
	webview.addEventListener('did-fail-load', (event) => {
	console.error('Lovable webview failed to load:', {
	errorCode: event.errorCode,
	errorDescription: event.errorDescription,
	validatedURL: event.validatedURL
	});
	alert('Unable to load Lovable. Please check your internet connection and try again.');
	});
