Chapter 6. Keeping States with Sessions

We already used Meteor's session object when we implemented our lazy load technique in an earlier chapter. In this chapter, we want to take a deeper look at it and learn how it can be used to create template-specific reactive functions.

In this chapter, we will cover the following topics:

• What sessions are
• How hot code pushes affect sessions
• Rerunning template helpers using sessions
• Rerunning functions
• Creating template-specific reactive functions

  Note

  If you've jumped right into the chapter and want to follow the examples, download the previous chapter's code examples from either the book's web page at https://www.packtpub.com/books/content/support/17713 or from the GitHub repository at https://github.com/frozeman/book-building-single-page-web-apps-with-meteor/tree/chapter5.

  These code examples will also contain all the style files, so we don't have to worry about adding CSS code along the way.
