lwcFetchContactRecord [Lightning Web Component HTML]

   <template>
    <lightning-card>
        <h3 slot="title">
            <lightning-icon icon-name="standard:contact" size="small"></lightning-icon> Fetching contact record from apex method without @wire        
        </h3> 
     
        <lightning-datatable data={contactData} columns={contactTable} key-field="Id"></lightning-datatable>

    </lightning-card>
</template>

<lightning-card>

<lightning-icon icon-name="standard:contact" size="small"></lightning-icon> Fetching contact record from apex method without @wire

</h3>

<lightning-datatable data={contactData} columns={contactTable} key-field="Id"></lightning-datatable>

</lightning-card>

</template>

Step 2:- Create Lightning Web Component : lwcFetchContactRecord.js

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

lwcFetchContactRecord.js [LWC JavaScript File]

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

import getContactList from '@salesforce/apex/lwcAppExampleApex.getContactList';
import {NavigationMixin} from 'lightning/navigation';

export default class lwcFetchContactRecord extends NavigationMixin (LightningElement) {
  @api title;
  @api greetings;

   @track contactData;
   @track conError;
   
   @track contactTable = [
     {label:'First Name', fieldName:'FirstName', type:'text'},
     {label:'Last Name', fieldName:'LastName', type:'text'},
     {label:'Phone', fieldName:'Phone', type:'text'},
     {label:'Email', fieldName:'Email', type:'email'},
   ];

   connectedCallback(){
      getContactList()
      .then(result =>{
          this.contactData = result;
      })
      .catch(error =>{
          this.conError=error;
      });
    }
     

}

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

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

import {NavigationMixin} from 'lightning/navigation';

export default class lwcFetchContactRecord extends NavigationMixin (LightningElement) {

@api title;

@api greetings;

@track contactData;

@track conError;

@track contactTable = [

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

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

{label:'Phone', fieldName:'Phone', type:'text'},

{label:'Email', fieldName:'Email', type:'email'},

];

connectedCallback(){

getContactList()

.then(result =>{

this.contactData = result;

})

.catch(error =>{

this.conError=error;

});

}

Step 3:- Create Lightning Web Component : lwcFetchContactRecord.js-meta.xml

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

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

  <?xml version="1.0" encoding="UTF-8"?>
<LightningComponentBundle xmlns="http://soap.sforce.com/2006/04/metadata">
    <apiVersion>45.0</apiVersion>
    <isExposed>true</isExposed>
    <targets>
        <target>lightning__AppPage</target>
        <target>lightning__RecordPage</target>
        <target>lightning__HomePage</target>
      </targets>
      <targetConfigs>
         <targetConfig targets="lightning__AppPage">
           <property name="title" type="string"/>
           <property name="greetings" type="string"/>
         </targetConfig>
      </targetConfigs>
</LightningComponentBundle>

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

<target>lightning__AppPage</target>

<target>lightning__RecordPage</target>

<target>lightning__HomePage</target>

</targets>

</targetConfig>

</targetConfigs>

</LightningComponentBundle>

Step 4:- Create Apex Controller : lwcAppExampleApex.cls

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

lwcAppExampleApex.cls [Apex Class]

   public with sharing class lwcAppExampleApex {

    @AuraEnabled
    public static List<Contact> getContactList(){
        List<Contact> conList = [Select Id, FirstName, LastName, Email, Phone From Contact Where Email !=null ];
        return conList;
    }   

}

public with sharing class lwcAppExampleApex {

@AuraEnabled

public static List<Contact> getContactList(){

List<Contact> conList = [Select Id, FirstName, LastName, Email, Phone From Contact Where Email !=null ];

return conList;

}
