Meteor\'s accounts-facebook package was very easy to set up. To input the Facebook app ID and secret token, I loaded my meteor web app in a browser, and clicked on
accounts-facebook
How about this:
Accounts.loginServiceConfiguration.insert({ service: "facebook", appId: "1292962797", secret: "75a730b58f5691de5522789070c319bc" });
