What are the best practices for logging in Express.js?

When logging in Express.js, it's important to use a structured logging library like Winston or Morgan. This helps in maintaining logs in a consistent format.

Why should I use a logging library instead of just console.log?

Using a logging library allows for better log management, including log levels, transports, and formats, which console.log lacks.

Can you give me an example of how to set up Winston in my Express app?

Sure! First, install Winston using npm. Then, create a logger instance and use it in your middleware to log requests.

What log levels should I use for different types of messages?

Common log levels include error, warn, info, debug, and silly. Use them to categorize the severity of your logs.
