Keep React Components Small

In React projects, complexity usually doesn’t arrive all at once. A small component gets a couple of conditionals, then data fetching, then a growing form state. After a while, the file ends up carrying the screen, the business rule, and the side effects all together.

Separate UI from Logic

If a component is both preparing data and drawing UI, it has two responsibilities. Splitting the data part into a hook and the UI into smaller components is usually enough.

function PostsPage() {
  const { posts, loading } = usePosts();

  if (loading) return <LoadingState />;
  return <PostList posts={posts} />;
}

Naming Defines Boundaries

Names like PostList, PostCard, PostMeta already communicate how much work a component should do. A good name is a good boundary.

Conclusion

Small components matter not just for reuse, but for making the code easier to think about. Readable UI code is the quiet foundation of good product development.
