jquery.cloudkit.js
------------------
An in-browser query-able JSON store for CloudKit.
This jQuery plugin produces in-browser collections of JSON data that map to a
remote CloudKit service. CloudKit is a schema-free auto-versioned RESTful JSON
store with OpenID and OAuth built in.
Using your in-browser database automatically updates the remote store. Querying
is accomplished via JSONQuery. JSONQuery is a superset of JSONPath. See "Usage"
for examples.

Usage
-----
On the server:
1) Mount two RESTful resource collections -- one for "notes" and another for
"things" -- in a file called "config.ru" (a rackup file):
require 'cloudkit'
expose :notes, :things
(This will mount the CloudKit REST API: http://getcloudkit.com/rest-api.html
for "notes" and "things.")
2) Start the server:
rackup config.ru
3) In an HTML file, include the library. (Instructions for building the library
are included below in the "Building" section.):
<script type="text/javascript" src="jquery.cloudkit.min.js"></script>
4) In your JavaScript code:
var store = $.cloudkit;
store.boot({
// booting the store reads the metadata on the server, loads existing data,
// and configures the local store for use
success: function() {
// the local store is now ready
// create a 'thing'
store.collection('things').create({name:"box"}, {
success: function(thing) {
// the 'thing' resource has now been created locally and posted
// to the server
alert(thing.json().name); // this will display "box"
// update the 'thing'
thing.update({name:"book"} {
success: function() {
// the updated 'thing' resource has been mirrored on the server
// and is ready for use again
alert(thing.json().name); // this is now "book"
// delete the 'thing'
thing.destroy({
success: function() {
// the 'thing' has now been deleted
}
}
}
})
}
});
// create a 'note'
store.collection('notes').create({foo:"bar"}, {
success: function(note) {
// do something with the note
}
});
// find all 'note' resources
var notes = store.collection('notes').all();
// get a specific note
var note = store.collection('notes').get(some_random_note.id());
// find all things having a name of 'book'
var matches = store.collection('things').query("?name='book'");
}
});
Building
--------
To build development and minified versions of the plugin:
$ rake dist
The jsmin gem is required for building the minified version. To install:
$ gem install jsmin
Running the Tests
-----------------
The CloudKit gem (0.10.0 or greater) is required for testing. To install:
$ gem install cloudkit
If you are running an older version of CloudKit, you can upgrade like this:
$ gem update cloudkit
To test:
$ rake
Note: You may need to refresh your browser if it launches before rack finishes
starting the test app.
