Hi Anil,

I have gone through your question. You can use the HTML iframe tag to show your attachments in pdf format.
  
<body>    
    <div class="slds">
        <iframe style="border: 1px solid" src="{!v.attachmentUrl}" type="application/pdf"/>
    </div>
</body>

Your attachments will be returned in blob format. So you need to convert them to pdf using getContentAsPDF() method.
Please check the link below for detailed information -

Hi Ajay,

Thank you for the update.

I have followed the above code. pfd is directly showing when component loads. My requirement is i need show the link when user clicks on link pdf should open to download.

Component:

<aura:component controller="CustomAttachmentViewerController"  >
    <aura:attribute name="attachmentUrl" type="String"/>
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
    
    <body>    
        <div class="slds">
            <iframe style="border: 1px solid" src="{!v.attachmentUrl}" type="application/pdf"/>
        </div>
    </body>
    
</aura:component>

JS Controller:

({
    doInit : function(component, event, helper) {
        
        var action = component.get("c.fetchContentDocument");
          
        action.setCallback(this, function(a) {
        
         console.log('Attachment data is:' + JSON.stringify(a.getReturnValue()));
         component.set("v.attachmentUrl", a.getReturnValue());
        
         
        });
        
        $A.enqueueAction(action);   
        
    }
})


Apex class:

public class CustomAttachmentViewerController {
    
         @AuraEnabled 
    public static string fetchContentDocument(){
        string attachmentId;
        string attachmentUrl;
        list<Account> acc=  [select id,(SELECT Id, Name FROM Attachments), name from Account where id = '0012v00002JTAwm'];
        attachmentId= acc[0].Attachments[0].id;
        attachmentUrl = URL.getSalesforceBaseUrl().toExternalForm() + '/servlet/servlet.FileDownload?file=' + attachmentId;
         system.debug('attachmentUrl'+attachmentUrl);
        return attachmentUrl;
    }

}

Thanks,
Anil Kumar
