In that blog we simply queried Accounts and displayed on lightning component.    The Salesforce Lightning component framework uses a stateful client and stateless server architecture. So we need to take a slightly different approach to do pagination than traditional VF. In order to maintain the value of offset. This is how we are doing. In Server Side Controller: We have a wrapper class AccountWrapper which wraps Accounts need to be displayed in accList, hasNext, hasPrev and offset. Server side action returns instance of AccountWrapper. In Client Side Controller : We have 4 action functions       1)  doinit  : This action function invokes on page load.
