USE CASE

Chat and Collaboration

Build powerful and feature-rich realtime chat and collaboration apps, powered by ﬂexible APIs and a global messaging infrastructure. Cross-device and cross-platform mean they work across web, iOS, Android, and the rest.

pubnub.publish({ channel: 'ChatRoomChannel', message: 'Hello, world!' }, (publishStatus) => {
if (publishStatus.error) {
console.error('Non 200 response', { publishStatus });
return;
}
console.log('I just published my hello!');
});

USE CASE

IoT Device Control

Securely monitor, control, provision and stream data between smart devices, sensor networks, hubs, and more. Trigger device action, monitor meta data, or stream and process incoming and outgoing data. PubNub provides the infrastructure and APIs for communication for any size IoT deployment.

# Handle PNPublishResult and PNStatus
def publish_callback(result, status):
if status.is_error():
# Handle error
return
print "I just received a publish callback!"
pubnub.publish().channel('sensor_channel').message({ temp: 400 }).async(publish_callback)

USE CASE

Realtime Updates

Keep everyone, and every device realtime. From mapping, geotracking and dispatch, to broadcasting alerts and up-to-the-millisecond updates, when something happens in the real world, it's reflected in your app.

pubnub.addListener({
status: function(statusEvent) {
if ((statusEvent.category === 'PNNetworkDownCategory') || (statusEvent.category === 'PNNetworkIssuesCategory')) {
// Handle error
return;
}
},
message: function(message) {
console.log('Realtime update!! ', message);
},
presence: function(presenceEvent) {
// handle presence
}
});
console.log('Subscribing..');
pubnub.subscribe({
channels: ['hello_world']
});
