Meteor.js Leader board example and some initial thoughts

leaderboard.js

// Set up a collection to contain player information. On the server,
// it is backed by a MongoDB collection named "players."

Players = new Meteor.Collection("players");

if (Meteor.is_client) {
  Template.leaderboard.players = function () {
    return Players.find({}, {sort: {score: -1, name: 1}});
  };

  Template.leaderboard.selected_name = function () {
    var player = Players.findOne(Session.get("selected_player"));
    return player && player.name;
  };

  Template.player.selected = function () {
    return Session.equals("selected_player", this._id) ? "selected" : '';
  };

  Template.leaderboard.events = {
    'click input.inc': function () {
      Players.update(Session.get("selected_player"), {$inc: {score: 5}});
    }
  };

  Template.player.events = {
    'click': function () {
      Session.set("selected_player", this._id);
    }
  };
}

// On server startup, create some players if the database is empty.
if (Meteor.is_server) {
  Meteor.startup(function () {
    if (Players.find().count() === 0) {
      var names = ["Ada Lovelace",
                   "Grace Hopper",
                   "Marie Curie",
                   "Carl Friedrich Gauss",
                   "Nikola Tesla",
                   "Claude Shannon"];
      for (var i = 0; i < names.length; i++)
        Players.insert({name: names[i], score: Math.floor(Math.random()*10)*5});
    }
  });
}

@rpflorence They haven't secured the mongodb store yet. 0.3.x Give it some time. The base looks really good, however.

meteor apps are insecure by default during production. now you can type $"meteor remove insecure" prior to deployment to remove this rapid application development feature.
