Create a server-side controller in Apex and use the @AuraEnabled annotation to enable access to the controller method.
Only methods that you have explicitly annotated with @AuraEnabled are exposed. Calling server-side actions aren’t counted against your org’s API limits. However, your server-side controller actions are written in Apex, and as such are subject to all the usual Apex limits.

A client-side controller handles events within a component. It’s a JavaScript resource that defines the functions for all of the component’s actions.A client-side controller is a JavaScript object in object-literal notation containing a map of name-value pairs. Each name corresponds to a client-side action. Its value is the function code associated with the action. Client-side controllers are surrounded by parentheses and curly braces. Separate action handlers with commas (as you would with any JavaScript map).
