How do you handle database errors in Node.js?

• Use try/catch blocks with async/await to catch exceptions.
• Handle errors in callbacks or promise .catch() when using promise-based APIs.
• Log errors for debugging.
• Return meaningful error messages to the client without exposing sensitive info.

Example:

try {

const user = await User.findById(id);
if (!user) throw new Error('User not found');

} catch (error) {

console.error(error);

res.status(500).send('Something went wrong');

}
