Show Lightning component on public website without authentication

I have posted few articles on Lightning OutIn this post, we will see how Lightning components can be displayed on public website. To access these Lightning components, users don’t need to login to Salesforce.

For this post, I will consider Text slider component created in this post. Using this same method, I have displayed Live demo of Lightning component on wordpress blog.

What do you need :

Option 1 [Used in this blog post] :

  • Public Site or Public Community Page
  • Visualforce wrapping Lightning App marked as Lightning out
  • This website – added in Salesforce CORS setting, so that Salesforce can be added as iframe in this website
  • Embed public site as iframe

Option 2 :

  • Follow this documentation
  • Import Lightning Out Javascript Library in your website using Community URL
  • Use JavaScript SDK to create Lightning application dynamically

Live Demo using Public Site and Visualforce :

<aura:application access="Global" extends="ltng:outApp" implements="ltng:allowGuestAccess">
 <aura:dependency resource="c:SliderDemo"/>
 <aura:dependency resource="c:AnimatedSlider"/>
 <aura:dependency resource="c:Slide"/>

See how we used ltng:allowGuestAccess in above Lightning application. It indicates that component can be used without authentication.

Below Visualforce page is used to surface Lightning component on public sites

<apex:page showHeader="false" standardStylesheets="false">
 <apex:stylesheet value="{!URLFOR($Resource.SLDS2_3_1, 'assets/styles/salesforce-lightning-design-system.min.css')}" />
 <apex:includeLightning />
 <div style="width:100%;height:100px;" id="lexContainer">
 <div style="height:6rem;" id="sliderDemo">
 <div role="status" class="slds-spinner slds-spinner_medium" >
 <span class="slds-assistive-text">Loading</span>
 <div class="slds-spinner__dot-a"></div>
 <div class="slds-spinner__dot-b"></div>

 $Lightning.use("c:SliderDemoApp", function() {
 function(cmp) {
 document.getElementById("sliderDemo").style.display = 'none';

Note : At time of writing this blog post, apex:slds tag does not work properly if images are used.

    Can we use the same public page to take user inputs as well?
