How can I get current worker id in loopback?

Question

When I run

NODE_ENV=production slc run 

loopback will automatically start workers for each CPU core.

I want to run some code only once, but every worker runs it. How can I check what worker it is currently running in?

I noticed it is using strong-supervisor behind the scenes to do its magic.

This is how I solved it:

var cluster = require('cluster');

if (cluster.isMaster || (cluster.isWorker && cluster.worker.id == '1'))) {
    //Do stuff
}
