Can we call multiple Apex classes from a Single Salesforce Lightning Component?

Hi Anurag,

Yes and No , no way so far for multiple apex controllers link to one aura component. but component allows include child components or inherited from super component. Each component has one controller.

using inheritance

<!-- BaseComponent -->
<aura:component extensible="true" controller="BaseComponentController">
</aura:component>

<!-- child component -->
<aura:component extends="BaseComponent"
controller="childComponentController">
</aura:component>
Invoke Base component helper method from child component, then invoke BaseComponentController methods.

Thanks.
