Caching collections in backbone.js?

Question

What would be the best way to ensure that my collection stays cached and thereby only gets fetched once?

Should I implement some sort of cache layer? Should I share the

Answer 1

A simple solution would be to make a global variable for your collection so that all your javascript code will use the same variable.

Just fetch the collection when the page loads

$(function() {
  myCollection = theCollection();
  myCollection.fetch();
});

Since var is not used to declared myCollection, then it becomes a global variable.

Of course this is a simple implementation. There are more robust implementations, but depending on your needs, they might be overkill.
