Subscribes to CouchDB's change feed and emits the JSON objects.
Usage
database: 'recipes' query: since: 50 heartbeat: 10000 filter: 'app/blueberries' vegetarian: true ;
All parameters except for database
are optional. All unrecognized query parameters are passed along so that CouchDB filter functions can use them.
You can also supply a filter as a plain JavaScript function. CouchStream will create a filter design document on the server and use that filter to retrieve the changes. Make sure that you don't reference any variables outside that function; they won't be available on the CouchDB server.
database: 'recipes' query: since: 50 { return doctype == 'recipe' && docingredients >= 0; } ;
