When i launch mrt, i have the following error :

Here is the code snippet in Accounts.js

Meteor.publish("userStatus", function() {
  return Meteor.users.find({
    "status.online": true
  });
});
....
UserStatus.on("sessionLogin", function(advice) {
  winston.log('info', 'User login', { metadata : JSON.stringify(advice)});
  return ;
});

Was working fine until i add the roles package ...
mrt test-packages user-status works fine - all green.

Check history: UserStatus is now UserStatus.events, and sessionLogin is now connectionLogin. Sorry for the hassle.

I would also recommend just putting advice directly in metadata rather than stringifying it. Why not just leave it as nested JSON?

i can see that the package i have is 0.2.0 when i run mrt :

user-status
    tag: https://github.com/mizzao/meteor-user-status.git#v0.2.0

this is confirmed by packages/user-status/smart.json

{
  "name": "user-status",
  "description": "User connection and status tracking for meteor",
  "homepage": "https://github.com/mizzao/meteor-user-status",
  "author": "Andrew Mao  (http://www.andrewmao.net)",
  "version": "0.2.0",
  "git": "https://github.com/mizzao/meteor-user-status.git",
  "packages": {}
}

i did mrt remove user-status then
mrt add user-status
Now everything is OK back to 0.3.4 ;)

maybe atmosphere was out of sync when i did mrt add ?

Copy/paste from console.log for JSON.stringify(advice) -> thanks for the review !

[mizzao]

I don't understand your last comment - do you still have a problem or is it fixed?

I suggest you update to newer versions if possible; we are taking advantage of improved connection handling in newer versions of Meteor. See meteor/meteor#1769.

[lc3t35]

it's fixed but i don't know why i was in 0.2.0 !

[lc3t35]

user-status
tag: https://github.com/mizzao/meteor-user-status.git#v0.3.4

Looking for an example in the tests, i've tryed this

UserStatus.events.on("connectionLogin", function(advice) {
  console.log(">>> user login");
});

But there is still TypeError: Cannot call method 'on' of undefined ???

if i look in the console, UserStatus has only the server side functions (defined in monitor.coffee) not the one of status.coffee : events and connections.

[mizzao]

You can't use UserStatus.events in the client. That is a server side event emitter. monitor.coffee is client code.

[lc3t35]

Ok moved to server side , works fine -> Why in package.js : api.export('UserStatus'); // on both then ?

[mizzao]

UserStatus has different exports on the server and client, but the object is available on both.

[lc3t35]

Thank you, perhaps clarify the documentation on what is available on client and server side for the same UserStatus.

[mizzao]

Yes, good idea. I will certainly do that.
