Realtime Data with WebSockets
Learn where Node.js WebSocket features fit in Wappler and how realtime flows differ from request-response APIs.
Introduction
Section titled “Introduction”Realtime Data with WebSockets is a Node.js-specific runtime feature in Wappler. Use it when the server should push updates to connected clients without waiting for page reloads, form submits, or polling.
It complements the normal route and API flow rather than replacing it: pages and APIs still handle the shared app structure, while sockets add live server-to-client updates.
Connected clients
Multiple listeners Shared realtime state
Complements APIs
Use with routes and normal data flows
Use WebSockets when clients should receive updates as events happen.
Keep request/response APIs for normal data loading, forms, and routing work.
Think of sockets as the live channel added on top of the shared Wappler app model.
