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

lwcIfElseCondition.js [LWC JavaScript File]

  import { api, LightningElement } from 'lwc';

export default class LwcIfElseCondition extends LightningElement {
    @api getShowContainer = false;

    showContainerData(event){
      this.getShowContainer = true;
      window.console.log('getShowContainer # ' + this.getShowContainer);
    }

    hideContainerData(event){
        this.getShowContainer = false;
      }

}

import { api, LightningElement } from 'lwc';

export default class LwcIfElseCondition extends LightningElement {

@api getShowContainer = false;

showContainerData(event){

this.getShowContainer = true;

window.console.log('getShowContainer # ' + this.getShowContainer);

}

hideContainerData(event){

this.getShowContainer = false;

}

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

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

lwcIfElseCondition.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>
        <target>lightning__Tab</target>
      </targets>
</LightningComponentBundle>

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

<target>lightning__AppPage</target>

<target>lightning__RecordPage</target>

<target>lightning__HomePage</target>

<target>lightning__Tab</target>

</targets>

</LightningComponentBundle>

Start Lightning Application

Step 4:- Create Lightning Application : lwcApp.app

From Developer Console >> File >> New >> Lightning Application

lwcApp.app [Component Application File]

  <aura:application extends="force:slds">
  <c:lwcIfElseCondition/>
</aura:application>

<aura:application extends="force:slds">

<c:lwcIfElseCondition/>

</aura:application>
