Disable Lightning Button After Click

In below example I’m creating Lead records from a Lightning Component. On Save button I’ve implemented the logic to hide the button after click.

Apex Controller:

public class SampleAuraController {
    
    @AuraEnabled
    Public static void createLead(Lead objLead){
        try{
            //Insert Lead Record
            insert objLead; 
        }catch(Exception e){
            //get exception message
            throw new AuraHandledException(e.getMessage());
        }
        finally {
        }
    } 
}

Lightning Component:

<!--Sample.cmp--> 
<aura:component controller="SampleAuraController" implements="flexipage:availableForAllPageTypes,force:appHostable">
    
    <!--Declare Attributes-->
    <aura:attribute name="isSpinner" type="boolean" default="false"/>
    <aura:attribute name="objLead" type="Lead" default="{'sobjectType':'Lead', 
                                                        'FirstName': '',
                                                        'LastName': '',
                                                        'Email': '', 
                                                        'Company': ''}"/>
    
    <!--Declare Handlers-->
    <aura:handler event="aura:waiting" action="{!c.handleShowSpinner}"/>
    <aura:handler event="aura:doneWaiting" action="{!c.handleHideSpinner}"/>
    
    <!--Component Start--> 
    <div class="slds-m-around--xx-large">
        <div class="container-fluid">
            <div class="form-group">
                <lightning:input name="fname" type="text" maxlength="50" required="true" label="First Name" value="{!v.objLead.FirstName}" />
            </div>
            <div class="form-group">
                <lightning:input name="lname" type="text" maxlength="50" required="true" label="Last Name" value="{!v.objLead.LastName}" />
            </div>
            <div class="form-group">
                <lightning:input name="emailId" type="email" maxlength="100" required="true" label="Email" value="{!v.objLead.Email}" />
            </div>
            <div class="form-group">
                <lightning:input name="company" type="text" maxlength="50" required="true" label="Company" value="{!v.objLead.Company}" />
            </div>
        </div>
        <br/>
        <lightning:button variant="brand" disabled="{!v.isSpinner}" label="{!v.isSpinner == true ? 'Saving...' : 'Save'}" onclick="{!c.handleLeadSave}" />             
    </div>
    <!--Component End-->
</aura:component>

Lightning JS Controller:

({
    //Handle Lead Save
    handleLeadSave : function(component, event, helper) {
        var objLead = component.get("v.objLead");
        var action = component.get("c.createLead");
        action.setParams({
            objLead : objLead
        });
        action.setCallback(this,function(a){
            var state = a.getState();
            if(state === "SUCCESS"){
                alert('Record is Created Successfully');
            } else if(state === "ERROR"){
                var errors = action.getError();
                if (errors) {
                    if (errors[0] && errors[0].message) {
                        alert(errors[0].message);
                    }
                }
            }else if (status === "INCOMPLETE") {
                alert('No response from server or client is offline.');
            }
        });       
        $A.enqueueAction(action);
    },
    
    //Call by aura:waiting event  
    handleShowSpinner: function(component, event, helper) {
        component.set("v.isSpinner", true); 
    },
    
    //Call by aura:doneWaiting event 
    handleHideSpinner : function(component,event,helper){
        component.set("v.isSpinner", false);
    }
})

Output:
