You are tasked with developing a logging system for an Express.js application to log every incoming request. How would you implement middleware to log the details of every request made to the application?

  • Create a middleware function that logs request details and use app.use to apply it globally to all routes.
  • Include logging code within each route handler to log request details individually.
  • Use a third-party logging library like Morgan and configure it within your Express.js application.
  • Use JavaScript's built-in console.log within each route to log request details.
To log details of every incoming request in an Express.js application efficiently, you should create a dedicated middleware function that logs request details and use app.use to apply it globally to all routes. This centralizes logging and avoids duplicating code in each route handler. The other options are either less efficient or not recommended for production applications.
