An attempt at mocking a drastic simplification of routing in Meteor

template.posts.html

<template name="posts" url="/posts" lang="en" layout="main">
  {{#contentFor region="header"}}
    <h1>Posts</h1>
  {{/contentFor}}
  {{#contentFor region="body"}}
    <article>
      {{#each posts}}
        <p>{{title}}</p>
      {{/each}}
    </article>
  {{/contentFor}}
  {{#contentFor region="footer"}}
    <div>...</div>
  {{/contentFor}}
</template>

<layout name="main">
  <header>{{#region name="header" /}}</header>
  <div>{{#region name="body"}}</div>
  <footer>{{#region name="footer" /}}</footer>
</layout>

template.posts.js

Template.posts.helpers({
  posts: function() {
    return Posts.find();
  }
});

Template.posts.routing({
  runBefore: function() {
    // this = template instance
    if (Meteor.isClient)
      Session.set("page", "posts");
  },
  runAfter: function() {
    Meteor.call("checkTumblr");
  },
  waitOnSubs: function() {
    return [
      Meteor.subscribe("posts");
    ];
  }
});
