ActiveTask API usage

[wawoimam]

I have seen activeTasks() listed as one of the API methods with cradle on the https://www.npmjs.com/package/cradle#other-api-methods .

I am new to couchDB and cradle and I want to use this method to get the list of active task _active_tasks as a json ducument like i saw on couchDB documentation http://docs.couchdb.org/en/2.0.0/api/server/common.html#api-server-active-tasks

I want someone to please give me an example of how to achieve this.
I want to use it for the client to know the replication status of the database. Thanks.
