By | March 30, 2021

In this blog, we will discuss on how to use Lightning component in Visualforce page. Kindly follow the below steps in order to use Lightning component in Visualforce page.

Create Lightning Component

SampleComponent

  • Firstly, in this lightning component, we are using ‘PassesValueFromVF‘ attribute which is set/pass from Visualforce page. Refer the below code to define component:-
<aura: component>
    <aura: attribute name="PassesValueFromVF" type="string"/>
    <b>Account Name from vf</b> : {!v.PassesValueFromVF}
    <p> 
    <button class="slds-button slds-button_brand" 
    onclick="{! c.showMessage}">Show Message</button>          
    </p>
</aura:component>

SampleComponentController

  • Secondly, we are using this controller to display alert message by clicking on the “Show Message” button which we define in the above component.
({
	showMessage: function(component, event, helper) {
        alert('Message from Lightning Component');
	}
})

Create Lightning Application

SampleApplication

  • Firstly, to display the Lightning component in Visualforce page, we need to create Lightning application.
  • In addition, the Lightning application include <aura: dependency> tag which indicate that it uses custom lightning component. Under the <aura: dependency> tag we need to mention our Lightning component name as shown in below code.
<aura: application extends="ltng:outApp" access="global">
        <aura: dependency resource="c:SampleComponent"/>
</aura: application>

Create Visualforce Page

sampleVF

  • Firstly, we need to add “<apex:includeLightning />” tag  which includes the Lightning component for Visualforce JavaScript library.
  • “$Lightning.use()” method is used to refer Lightning application in which we need to add our Lightning application name.
  • “$Lightning.createComponent” is used to create Lightning component dynamically in which we need to add our Lightning component name.
  • PassesValueFromVF” is a parameter, which is used to pass the value from Visualforce to Lightning component. (refer the below code)
<apex:page>
  <apex:includeLightning />
    <div  id="compContainer" />
  <script>
     $Lightning.use("c:SampleApplication", function() {
         $Lightning.createComponent("c:SampleComponent",
             {PassesValueFromVF:"Micro System"},
             "compContainer",
             function(cmp) {
          console.log("c:VFPageApp loaded successfully in VF page");
             }
         );
     });
  </script>
</apex:page>

Here is the output, where we display account name “Micro System” which we pass from visualforce page. Also, when user click on “Show Message” button an alert message will through from lightning controller method.
