Publishing only parts of data

To make our front page future-ready, we will need to limit the amount of posts shown on it, as we will probably have a lot of posts added with time.

For this, we will create a new publication called limited-posts, where we can pass a limit option to the posts' find() function and add it to our publications.js file, as follows:

Meteor.publish('limited-posts', function () {
  return Posts.find({}, {
    limit: 2,
