Step 1:- Create Apex Controller : lwcAppExampleApex.cls

SFDX:Create Apex Class >> New >> lwcAppExampleApex.cls

lwcAppExampleApex.cls [Apex Class]

 public with sharing class lwcAppExampleApex {   
    

   //delete multiple contact record in LWC
    @AuraEnabled(cacheable=true)
    public static List<Contact> fetchContactRecord(){
        List<Contact> conList = [Select Id, FirstName, LastName, Email, Phone From Contact Order By createdDate desc Limit 10 ];
        return conList;
    }

    @AuraEnabled
    public static List<Contact> deleteMultipleContactRecord(List<String> conObj){
        List<Contact> conObjItem = new   List<Contact>();
      List<Contact> conObjList = [Select Id, Name  From Contact Where Id IN:conObj];
      for(Contact con:conObjList){
        conObjItem.add(con);
      }
      if(conObjItem.size()>0){
          try{
            delete conObjItem;           
          }
          catch (Exception exp) {
            throw new AuraHandledException(exp.getMessage());
        }
      }
      return fetchContactRecord();
    }

}

public with sharing class lwcAppExampleApex {

//delete multiple contact record in LWC

@AuraEnabled(cacheable=true)

public static List<Contact> fetchContactRecord(){

List<Contact> conList = [Select Id, FirstName, LastName, Email, Phone From Contact Order By createdDate desc Limit 10 ];

return conList;

}

@AuraEnabled

public static List<Contact> deleteMultipleContactRecord(List<String> conObj){

List<Contact> conObjItem = new List<Contact>();

List<Contact> conObjList = [Select Id, Name From Contact Where Id IN:conObj];

for(Contact con:conObjList){

conObjItem.add(con);

}

if(conObjItem.size()>0){

try{

delete conObjItem;

}

catch (Exception exp) {

throw new AuraHandledException(exp.getMessage());

}

return fetchContactRecord();

}

})

.catch(error =>{

this.errorMsg =error;

Step 4:- Create Lightning Web Component : lwdDeleteMultipleRecord.js-meta.xml

SFDX:Lightning Web Component >> New >> lwdDeleteMultipleRecord.js-meta.xml

lwdDeleteMultipleRecord.js-meta.xml [LWC Meta Data XML]

  <?xml version="1.0" encoding="UTF-8"?>

FAQ (Frequently Asked Questions)

How do I delete records in LWC?

To delete records in LWC, we first need to import fetchOpportunities method from Apex Controller using @salesforce/apex/ module in JS Controller. Then, include deleteRecord method from lightning/uiRecordApi module.

How many records can be deleted at once using the mass delete tool?

You can delete up to 250 items at one time. When you delete a record, any associated records that display on that record's related lists are also deleted.

How do you refresh apex in LWC?

To refresh stale Apex data, invoke the Apex method and then call getRecordNotifyChange(recordIds) to update the Lightning Data Service (LDS) cache. Lightning Data Service doesn't manage data provisioned by imperative Apex calls.
