You can extend your Express.js server by writing custom middleware functions. These functions intercept every request and allow you to add custom functionality or filters. You can also pass the request to other middleware functions.
You can use Chrome's DevTools to debug Node.js applications. To do this, you need to set your Node.js app as a remote target using the `--inspect` flag when starting the `node` process. Once your app is registered, you can open the DevTools for Node in Google Chrome.
