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();

}

Step 2:- Create Lightning Web Component : lwdDeleteMultipleRecord.html

SFDX:Lightning Web Component >> New >> lwdDeleteMultipleRecord.html

lwdDeleteMultipleRecord.html [Lightning Web Component HTML]

  <template>

Step 3:- Create Lightning Web Component : lwdDeleteMultipleRecord.js

SFDX:Lightning Web Component >> New >> lwdDeleteMultipleRecord.js

lwdDeleteMultipleRecord.js [LWC JavaScript File]

  import { LightningElement, wire,api, track } from 'lwc';

    getSelectedIdAction(event){
        const selectedContactRows = event.detail.selectedRows;
        window.console.log('selectedContactRows# ' + JSON.stringify(selectedContactRows));
        this.selectedContactRows=[];
        
        for (let i = 0; i<selectedContactRows.length; i++){
            this.selectedContactIdList.push(selectedContactRows[i].Id);

    }
  
   
    deleteContactRowAction(){
        deleteMultipleContactRecord({conObj:this.selectedContactIdList})
        .then(()=>{
            this.template.querySelector('lightning-datatable').selectedContactRows=[];

            const toastEvent = new ShowToastEvent({
                title:'Success!',
                message:'Record deleted successfully',
                variant:'success'
              });
              this.dispatchEvent(toastEvent);

            return refreshApex(this.wireContact);

            window.console.log('unable to delete the record due to ' + JSON.stringify(this.errorMsg));

import { LightningElement, wire,api, track } from 'lwc';

import fetchContactRecord from '@salesforce/apex/lwcAppExampleApex.fetchContactRecord';

import deleteMultipleContactRecord from '@salesforce/apex/lwcAppExampleApex.deleteMultipleContactRecord';

import { refreshApex } from '@salesforce/apex';

import {ShowToastEvent} from 'lightning/platformShowToastEvent';

export default class LwdDeleteMultipleRecord extends LightningElement {

@api columns =[

{ label: 'First Name', fieldName: 'FirstName', type:'text'},

{ label: 'Last Name', fieldName: 'LastName',type:'text' },

@wire (fetchContactRecord) wireContact;

@api selectedContactIdList=[];

getSelectedIdAction(event){

return refreshApex(this.wireContact);

})

.catch(error =>{

this.errorMsg =error;

window.console.log('unable to delete the record due to ' + JSON.stringify(this.errorMsg));

});

}

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"?>
