How do I handle errors in MongoDB with Node.js?

You can handle errors in MongoDB with Node.js by using try-catch blocks or by handling promise rejections. Would you like an example?

Yes, please provide an example using async/await.

Sure! Here's a simple example:

async function connectToDatabase() {
    try {
        await mongoose.connect('mongodb://localhost:27017/mydatabase');
        console.log('Database connected successfully!');
    } catch (error) {
        console.error('Database connection error:', error);
    }
}

This will catch any connection errors and log them.

What about handling errors during data operations?

For data operations, you can also use try-catch. For example:

async function createUser(userData) {
    try {
        const user = await User.create(userData);
        console.log('User created:', user);
    } catch (error) {
        console.error('Error creating user:', error);
    }
}
