Publish Data

Catalyst Data Streams enables you to publish real-time data to a channel. Any active subscribers connected to that channel will receive the published data instantly through their WebSocket connections.

The datastreams reference used in the code below is the component instance created earlier.

Publish Data to a Channel

You can publish data to a channel by passing the channel ID and the data payload to the publishData() method. You can structure the payload as needed, including fields like type, data, and timestamp. The promise returned here will be resolved to an object confirming the publish operation.

Parameters Used

//Publish data to all subscribers of the channel
const publishRes = await datastreams.publishData(CRICKET_CHANNEL_ID, {
  type: "cricket_score_update",
  data: mockCricketData,
  timestamp: new Date().toISOString()
});
