Backbone Capped Collections

Capped Collections for BackboneJS

Getting Started

Install the module with: npm install backbone-cappedcollection

Client-side

<script type="text/javascript" src="underscore.js"></script>
<script type="text/javascript" src="backbone.js"></script>
<script type="text/javascript" src="lib/index.js"></script>
<script type="text/javascript">
var myColl = new Backbone.CappedCollection([
  {name: "Twitter", url: "http://twitter.com/FGRibreau"}, // Will be removed
  {name: "Bringr",  url: "http://brin.gr"},
  {name: "Redsmin", url: "http://redsmin.com"},
], {
  // {optional} Capped Collection size (default. 5)
  cap:2,
  // {optional} From where should it start to remove elements, "first" or "last" (default. first)
  capRemove:'first'
});

myColl.length; // == 2

myColl.add({name: "Github", url: "http://github.com"});
myColl.add({name: "NodeJS", url: "http://nodejs.org/"});

myColl.length; // == 2

myColl.toJSON(); // [{"name":"Github","url":"http://github.com"},{"name":"NodeJS","url":"http://nodejs.org/"}]

// Other Backbone methods (.add, .reset, ...) should work as expected as well.
</script>

Server-side (NodeJS)

var Backbone = require('backbone');
// Wrap it
Backbone = require('backbone-cappedcollection')(Backbone);

// [... same as the client-side code above ...]
