How can I implement error handling in my backend application?

Implementing error handling involves using try-catch blocks, logging errors, and returning meaningful responses.

What are some common error types I should handle?

Common error types include validation errors, database errors, and network errors. Each should be handled appropriately.

Can you give me an example of a try-catch block?

Sure! Here's a simple example:

try {
    // code that may throw an error
} catch (error) {
    console.error('Error occurred:', error);
    // handle the error
}

How do I log errors effectively?

Use a logging library like Winston or Bunyan to log errors with timestamps and severity levels for better tracking.
