Download the SDK from the following sources or use CommandBox:
box install cfcouchbase to install the SDK- Bleeding Edge + More: http://integration.stg.ortussolutions.com/artifacts/ortussolutions/cfcouchbase/
The CFCouchase SDK is contained in a single folder. The easiest way to install it is to copy
cfcouchbase in the web root. For a more secure installation, place it outside the web root and create a mapping called cfcouchbase.this.mappings[ '/cfcouchbase' ] = 'C:\path\to\cfcouchbase';
Now that the code is in place, all you need to do is create an instance of
cfcouchbase.CouchbaseClient for each bucket you want to connect to. The CouchbaseClient class is thread safe and you only need one instance per bucket for your entire application. It is recommended that you store the instantiated client in a persistent scope such as application when your app starts up so you can access it easily.public boolean function onApplicationStart(){
application.couchbase = new cfcouchbase.CouchbaseClient();
return true;
}
However, we would recommend you use a dependency injection framework like WireBox to create and manage your Couchbase Client:
// Map our Couchbase Client via WireBox Binder
map( "CouchbaseClient" )
.to( "cfcouchbase.CouchbaseClient" )
.initArg( name="config", value={} )
.asSingleton();
When you are finished with the client, you need to call its
shutdown() method to close open connections to the Couchbase server. The following code sample will wait up to 10 seconds for connections to be closed.public boolean function onApplicationEnd(){
application.couchbase.shutdown( 10 );
return true;
}
Danger: Each Couchbase bucket operates independently and uses its own authentication mechanisms. You need an instance ofCouchbaseClientfor each bucket you want to interact with. It is also extremely important that you shutdown the clients whenever your application goes down in order to gracefully shutdown connections, else your server might degrade.
