How can I handle errors in Node.js when connecting to a database?

You can use try-catch blocks for synchronous code and handle errors in callbacks or use promises for asynchronous code.

What about using async/await? How does that work?

With async/await, you can wrap your database calls in a try-catch block to catch any errors that occur during the operation.

Can you give me an example of that?

Sure! Here's a simple example:

async function connectToDatabase() {
    try {
        const connection = await db.connect();
        console.log('Connected to database');
    } catch (error) {
        console.error('Database connection error:', error);
    }
}

What should I do if the database is down?

You can implement retry logic or fallback mechanisms to handle such scenarios gracefully.
