You do not need Node.js to build real-time features.
Many developers worry that ColdFusion is losing modern capabilities. This is not true. ColdFusion 2025 did not remove WebSocket support. It only removed Flash and Flex features.
You can build live tools directly in ColdFusion.
What you can build:
- Live chat apps
- Real-time dashboards
- Push notifications
- Live data feeds
How it works:
- The cfwebsocket tag creates a JavaScript object on the client side.
- You define channels in your Application.cfc file.
- You use the WsPublish() function to send messages from the server.
This setup removes the need for a separate Socket.IO server. You do not need to manage a second runtime.
Two things to remember:
- Adobe ColdFusion supports this feature, but Lucee does not.
- You must use WSS for secure connections in production.
- Your load balancer must allow WebSocket traffic.
