💎 When running an Express server, shutting it down gracefully ensures that ongoing requests complete and resources like database connections are properly cleaned up before the app exits.
💎 A graceful shutdown ensures that ongoing requests finish before the app exits.
Code Example
const express = require("express"); const app = express(); const PORT = 3000; const server = app.listen(PORT, () => { console.log(`Server running on port ${PORT}`); }); const shutdown = () => { console.log("\nShutting down..."); server.close(() => { console.log("Server closed. Cleanup complete."); process.exit(0); }); }; process.on("SIGINT", shutdown); process.on("SIGTERM", shutdown); 🌟 Key Takeaways
✅ Listen for SIGINT/ SIGTERM signal 🚨 to trigger shutdown
✅ Ensures active requests complete 👍 before exiting
✅ Calls server.close() to stop the server and release the port
This ensures a smooth exit without dropping connections abruptly! 🚀✨
