Meteor Instance ID

core
1

hi,

I needed to integrate a parameter in my meteor application that allows me to clean up certain caching systems inside my application every time the meteor instance is restarted.
(my case study here: https://github.com/Keplerjs/Kepler/issues/74)

already there is a global variable in meteor that is generated uniquely for each instance?

Or should I generate a random variable in Meteor.startup ???

many tnks,
Stefano

I think that’s the way to go. Obviously, if you use multiple server instances in an application, there will be an ID for each.

This package was designed specifically for that purpose… https://atmospherejs.com/socialize/server-presence

ServerPresence.serverId()

Of course you can, and yes the package was designed as a way to run server specific cleanup tasks when a server goes down.

If you are doing cleanup, and don’t need the serverId for some other reason. There is the ServerPresence.onCleanup method to register a callback to run when your app exits.
