Hi Ajit,

For now there is now component available which helps to replicate the record page as <apex:detail> provides. But what good and new component is available from winter 17 which help developers to show record details in lightning custom components without writing Apex class.

Lightning Data Service is similar to standard controller we use in VF pages which can access the fields values on page without having apex code written for it. Yo can check the above link:

Lightning Data Service

This the best bet we have for now in lightning world.

 

Thanks
