Quick Start
Suppose you wanted to monitor the temperature of a bunch of remote gauges so things don't blow up.
A typical setup for this would be to run a monitor Node
and a gauge Node
.
This would look like:
//// Gauges server// var gossip = ; // Nodes are the building block of gossip. You should run one node per process.// They can send and receive messages to / from a cluster of nodes.var node = 'ipc://temp-gauges'; // You can subscribe to messages you are interested in.// Any node can check your temperature by sending you a `check-temp` message. Yay!node; //// Monitor server// var gossip = ; var node = 'ipc://temp-monitor'; // Join the monitor to the gauges. This will allows the node to send messages to any nodes that are known// by the node you are connecting to.node; ;
