Runtime logs for Node.js applications

Runtime logs record everything that happens on your application while it's actively running on the server. This is useful when your application was successfully deployed but errors occur only during actual use—for example, when a user visits a page or triggers a specific action. Runtime logs are available for server-side applications such as Next.js, Nuxt, and Express. If you deployed your application before this release, you'll need to redeploy to start seeing logs; a notice will appear in the Runtime Logs view if a redeploy is required. Static sites like Vite won't produce runtime logs since they have no server process running.
