Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Example: Interactive Visualforce Page without Replay

The interactive Visualforce example shows you how to implement Streaming API from a Visualforce page. The sample uses the Dojo library and CometD to subscribe to PushTopic events.

On the Visualforce page, you enter the name of the PushTopic channel you want to subscribe to and click Subscribe to receive notifications on the page. Click Unsubscribe to unsubscribe from the channel and stop receiving notifications.

This sample doesn’t use the replay extension and can’t receive past events.
