How to create menu in Node.JS

From the times of my Borland C programming where we had a fixed-width terminal that never changed size I had come up with the following code in Node.JS to now make it dynamically adjustable. The following code is just a skeleton and may be adjusted to your needs.

const readline = require('readline');

const rl = readline.createInterface({
	input: process.stdin,
	output: process.stdout,
});

function displayMenu() {
	console.clear();

	// Get console dimensions
	const terminalWidth = process.stdout.columns; // Total width in characters
	const terminalHeight = process.stdout.rows; // Total height in characters

	// Calculate center position for menu text horizontally and vertically
	const horizontalCenterOffset = (terminalWidth - 25) / 2; // Adjust '25' if your menu length changes
	const verticalCenterOffset = (terminalHeight - 7) / 2; // Adjust '4' to account for the number of lines used by the menu

	// Clear the console and print a centered title
	console.log("\n".repeat(verticalCenterOffset)); // Move cursor down vertically
	console.log(" ".repeat(horizontalCenterOffset) + "Select an option:".padEnd(terminalWidth));
	console.log(" ".repeat(horizontalCenterOffset) + "1. Option 1");
	console.log(" ".repeat(horizontalCenterOffset) + "2. Option 2");
	console.log(" ".repeat(horizontalCenterOffset) + "3. Exit");

	console.log();
	rl.question(" ".repeat(horizontalCenterOffset) + "Enter your choice: ", (answer) => {
		switch (parseInt(answer)) {
			case 1:
				console.clear();
				console.log("You chose option 1!");
				break;
			case 2:
				console.clear();
				console.log("You chose option 2!");
				break;
			case 3:
				console.clear();
				console.log("Exiting...");
				rl.close();
				process.exit(0);
				break;
			default:
				console.log("Invalid choice. Please enter a number between 1 and 3.");
		}

		// Wait for ENTER before redrawing the menu
		rl.question('\nPress ENTER to continue...\n', () => {
			main(); // Call main() again after ENTER
		});
	});
}

function main() {
	displayMenu(); // Initially display the menu
}

main(); // Start the main function
