  }

Logging HTTP Requests

Log details of HTTP requests for better monitoring.

  const express = require('express');
  const logger = require('magic-logger');
  const app = express();

  app.use(logger.logHttpRequest);

  const express = require('express');
  const logger = require('magic-logger');
  const app = express();

  logger.setFormat('[{level}] {timestamp} - {message}');
  logger.addTransport(new ConsoleTransport());

  app.use(logger.logHttpRequest);

  app.get('/', (req, res) => {
    logger.info('Home route accessed');
    res.send('Welcome to the Home Page');
  });

  app.post('/submit', (req, res) => {
    logger.info('Data submitted');
    res.send('Data received');
  });

  app.use((err, req, res, next) => {
    logger.error('An error occurred: ' + err.message);
    res.status(500).send('Server Error');
  });

  app.listen(3000, () => {
    logger.info('Server running on port 3000');
  });
