Improving User Engagement: Refactoring the React LikeButton

In the Astro-portfolio project, I recently revisited how we handle user interactions within our components. Specifically, I focused on the LikeButton component, which serves as a primary touchpoint for readers to engage with content.

The Challenge

Previously, the LikeButton interaction felt static. It fulfilled its basic function, but it lacked the fluid responsiveness that modern React users expect. The state transitions were abrupt, and the lack of visual feedback made the interaction feel disconnected from the user's intent.

The Refactor

To improve the experience, I refactored the component to ensure smoother state handling and immediate UI updates. Instead of relying on complex effects, I simplified the logic to manage local state efficiently:

const LikeButton = ({ initialLikes }) => {
  const [likes, setLikes] = useState(initialLikes);
  const [liked, setLiked] = useState(false);

  const handleLike = () => {
    setLiked(!liked);
    setLikes(prev => (liked ? prev - 1 : prev + 1));
  };

  return (
    <button onClick={handleLike} className={liked ? 'active' : ''}>
      {likes} Likes
    </button>
  );
};

This refactoring ensures that the component remains predictable. By separating the visual state (liked) from the numeric state (likes), we eliminate potential race conditions and keep the rendering cycle lean.

The Takeaway

User experience in component-driven development is often found in the small details. When refining interactive elements, prioritize clear state ownership and immediate visual feedback. Next time you work on a UI feature, audit your state logic—if it feels sluggish, start by simplifying your state transitions before adding extra animation libraries.
