How can I implement logging in Next.js API routes?

You can implement logging in Next.js API routes by using middleware or directly in your API route handlers. Would you like an example?

Yes, please provide an example of logging in an API route.

Sure! You can create a middleware function that logs requests. Here's a simple example:

// middleware/logger.js
export function logger(req, res, next) {
  console.log(`${req.method} ${req.url}`);
  next();
}

// pages/api/example.js
import { logger } from '../../middleware/logger';

export default function handler(req, res) {
  logger(req, res, () => {
    res.status(200).json({ message: 'Logged!' });
  });
}

This will log the method and URL of each request.

How can I log errors in my API routes?

You can catch errors in your API routes and log them using a try-catch block. Here's an example:

export default async function handler(req, res) {
  try {
    // Your logic here
  } catch (error) {
    console.error('Error occurred:', error);
    res.status(500).json({ message: 'Internal Server Error' });
  }
}
