How can I handle errors using Winston logging?

How can I handle errors using Winston logging?

You can handle errors in Winston by using the error level for logging. This allows you to capture error messages effectively.

Can you show me a code example of logging an error?

Sure! Here's a simple example:

const winston = require('winston');

const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.File({ filename: 'error.log', level: 'error' }),
  ],
});

try {
  // some code that may throw an error
} catch (error) {
  logger.error('Something went wrong:', error);
}

What are the best practices for error logging?

Best practices include logging meaningful error messages, using different log levels, and ensuring logs are stored securely for analysis.

How can I integrate Winston with Express for error handling?

You can use middleware in Express to catch errors and log them using Winston. Here's a quick example:

app.use((err, req, res, next) => {
  logger.error(err.message);
  res.status(500).send('Something broke!');
});
