How to invoke an LWC Component function from Aura Component

By | February 16, 2022

In this post, we will learn how to Invoke an LWC Component function from Aura Component when an event occurs in Aura.

If we want to Invoke LWC function, we need to follow the steps mentioned below:

  • LWC component function should be declared as public starting using @api decorator.
  • We can invoke the LWC component through the Aura component using aura:id.

The code below is an example where we have a lightning button, ‘Call LWC Function,’ which invokes the LWC component function and displays text as ‘ LWC Function Invoked through Aura Component. ‘

The below code is for the LWC Component which will display text when Invoked by the Aura Component.


   <div class="slds-box">  
      <div if:true={DisplayText}>{textValue}</div> 


import { LightningElement, track, api } from 'lwc';  
 export default class lWCComponent extends LightningElement
  DisplayText = false;
  textValue='LWC Function Invoked through Aura Component'  
  @api LWCFunction()
    this.DisplayText = true; 

The following code is the Aura Component to call the above LWC component on a button click.


<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,force:lightningQuickAction" access="global" >  
  <div class="slds-box">
     <lightning:button variant="brand" label="Call LWC Function" onclick="{! c.handleClick }" />  
   <c:lWCComponent2 aura:id="lWCComponent2"></c:lWCComponent2>  


  handleClick : function(component, event, helper) 
      component.find('lWCComponent2').LWCFunction ();
