Environment variables are also available to the server via the process.env object.
if (Meteor.isServer) {
Meteor.startup(function () {
// detect environment by getting the root url of the application
console.log(JSON.stringify(process.env.ROOT_URL));
// or by getting the port
console.log(JSON.stringify(process.env.PORT));
// alternatively, we can inspect the entire process environment
console.log(JSON.stringify(process.env));
});
}
