Step 3: Add the FeelbackPulse component to the layout page

Now you are ready to add the Like button to your blog post page. Let’s suppose you want to add a Heart button near your blog post title.

For this guide, we will create a new component named BlogPostTitle which will display the title and the like button.


import FeelbackPulse from "astro-feelback/components/FeelbackPulse.astro";
import "astro-feelback/styles/feelback.css";

// here you will copy the content-set id from the panel
const CONTENT_SET_LIKES = "your-content-set-id-from-panel";

interface Props {
    date: Date
    title: string

<div class="title-header">
    <span class="post-date">{}</span>

    <FeelbackPulse contentSetId={CONTENT_SET_LIKES}
        preset="heart" // <-- shows the Heart icon
        showCount // <-- shows the likes count

You can use the BlogPostTitle component inside your BlogPost layout page. The result should be something like this:

Additional documentation with all properties and customization you can use are available inside the dedicated Astro integration guide.

Step 4: (Optional) Customize the component style

You can override the predefined style with additional CSS.

For example, you can add some selector to change the button icons size and set some custom value.

import "astro-feelback/styles/feelback.css";
<style is:global>
   .feelback-icon svg {
     width: 24px;
     height: 24px;

Full documentation with advanced customization is available inside the Astro integration guide.
