Stream Controller Overview
When enabled via the PubNub Admin Console, the Stream Controller feature provides PubNub developers the ability to efficiently subscribe to multiple channels via Channel Multiplexing (MXing) and Channel Groups.
Publish and Subscribe Overview
PubNub utilizes a Publish/Subscribe model for real-time data streaming and device signaling which lets you establish and maintain persistent socket connections to any device and push data to global audiences in less than ¼ of a second.
How do you manage lifecycle?
It is users responsibility to prepare client's configuration instance and pass it during PubNub client instantiation. As long as there is a reference to the client instance it will be alive. The initialized client doesn't perform any activities until activated by user commands.
Here Now
DESCRIPTION
You can obtain information about the current state of a channel including a list of unique user-ids currently subscribed to the channel and the total occupancy count of the channel by calling the hereNow() function in your application.
Publish
DESCRIPTION
The publish() function is used to send a message to all subscribers of a channel. To publish a message you must first specify a valid publishKey at initialization. A successfully published message is replicated across the PubNub Real-Time Network and sent simultaneously to all subscribed clients on a channel.
