🎙️ I've been on the PodRocket podcast by @logrocket.bsky.social recently, talking some more about useCallback, useMemo, "the latest ref pattern" and the React Compiler:

This is probably one of my best articles that isn’t about React Query. I just re-read it and love everything about it. I probably peaked at that time. Give it a read:

Component Composition is great btw

Component composition is one of the best parts of React, and I think we should take more time to break our components into manageable parts before littering one component with conditional renderings.

Great read:

Search Params Are State — Treat Them That Way Search params have been historically treated like second-class state. They're global, serializable, and shareable — but in most apps, they’re still hacked...

Which one do you like better? I think it’s not even close. The version with early returns gets clear branching, type-narrowing (TS knows that posts are defined after we check for isPending and isError), and evolves a lot better (can easily add branches) than the version with conditional rendering.

const Layout = ({ category, children }) => (
<div className="p-4">
<h2 className="text-xl font-bold mb-4">{category.charAt(0).toUpperCase() + category.slice(1)} Posts</h2>
{children}
</div>
);

export const Posts = ({ category }) => {
const { isPending, isError, data: posts } = usePosts(category);

if (isPending) {
return (
<Layout category={category}>
<div className="mb-4 text-blue-500">Loading posts...</div>
</Layout>
);
}

if (isError) {
return (
<Layout category={category}>
<div className="mb-4 text-red-500">{error.message}</div>
</Layout>
);
}

if (posts.length === 0) {
return (
<Layout category={category}>
<div className="mb-4">No posts found for this category</div>
</Layout>
);
}

return (
<ul className="space-y-4">
{posts.map((post) => (
<li key={post.id} className="border p-3 rounded">
<h3 className="font-semibold">{post.title}</h3>
<p>{post.body}</p>
</li>
))}
</ul>
);
};
