Fix critical issues: missing blog image and misleading code examples.

The blog post references a missing image file at line 7 (./images/post-image.png). This file does not exist in the post directory, which will result in a broken image when rendered. Add the image file to content/blog-post-2026-06-22/images/post-image.png or update the frontmatter with the correct path.

Additionally, the code examples contradict the post title and promise. Lines 24-34 and 53-71 contain no actual React hooks usage (no useState, useEffect, useCallback, useMemo, etc.), yet the title claims "A Practical Guide" to React hooks. The first example is a plain function named like a custom hook but with no React API calls; the second is a basic component with zero hooks. Rewrite the examples to demonstrate practical React hooks patterns or revise the title to match the content.

Minor grammar fixes needed:

  • Line 12: "React hooks continues" → "React hooks continue" (plural verb)
  • Line 14: "Why React hooks Matters" → "Why React Hooks Matter" (parallel structure)

around lines 1 - 8, This blog post has three critical issues to fix. First, add
the missing image file to content/blog-post-2026-06-22/images/post-image.png or
update the frontmatter image path to reference an existing file. Second, the
code examples in lines 24-34 and 53-71 do not demonstrate any actual React hooks
usage (no useState, useEffect, useCallback, useMemo, etc.) despite the post
title promising "A Practical Guide" to React hooks, so rewrite these examples to
show practical React hooks patterns with proper hook implementations. Third, fix
two grammar issues: change "React hooks continues" to "React hooks continue" on
line 12 and "Why React hooks Matters" to "Why React Hooks Matter" on line 14 to
use correct plural verb agreement and parallel structure.

Suggestion: This post is added under content/blog-post-2026-06-22/, but the content collection is configured to load only content/blog/**/*.mdx (velite.config.ts), so this new article will never be indexed, listed, or routable in the blog. Move the file under content/blog/ (or expand the collection pattern) so the post is actually published. [incomplete implementation]

Severity Level: Critical 🚨 
- ❌ New React hooks article never appears in blog index.
- ❌ Article route not generated; direct URL returns 404.
- ⚠️ Sitemap and tag pages omit this post entirely.
- ⚠️ Homepage latest posts section never shows this article.
Steps of Reproduction ✅ 
1. Open `velite.config.ts` at `/workspace/frontend-junction/velite.config.ts` and observe
the `posts` collection definition at lines 11–13: `pattern: 'blog/**/*.mdx'` with `root:
'content'` at line 31, meaning only files under `content/blog/...` are collected into
`posts`.

2. Note the new article file location from this PR:
`content/blog-post-2026-06-22/react-hooks-in-2026-a-practical-guide.mdx` (shown in the
diff), which is a sibling of `content/blog` (confirmed by `content/` listing) and
therefore does not match the `blog/**/*.mdx` pattern.

3. Start the app (`npm run dev`) and visit `http://localhost:3000/blog`, which is served
by `app/blog/page.tsx`; this page imports `posts` from `#site/content` at line 1 and
builds the index from `sortPosts(posts.filter((post) => post.published))` at lines 29–30,
but because the new MDX file is outside `content/blog`, it is never included in `posts`
and thus does not appear in the blog list.

4. Attempt to access a detail route under `/blog/...` (served by
`app/blog/[...slug]/page.tsx`, which maps static params from `posts` at lines 71–73 and
finds posts by `slugAsParams` at lines 18–21); since the new file never becomes a `Post`
in `posts`, no static path is generated and `getPostFromParams` returns `undefined`,
causing `notFound()` at line 79 and making the article unroutable.

# React hooks in 2026: A Practical Guide

React hooks continues to evolve in 2026, and staying current with the latest patterns and best practices is essential for building modern, performant web applications. In this guide, we'll explore practical techniques you can implement today.

## Why React hooks Matters

Understanding react hooks is crucial for frontend developers who want to build responsive, accessible, and maintainable applications. Whether you're working on a small project or a large-scale enterprise application, these concepts apply.

## Key Concepts

### 1. Foundation Principles

The core principles behind react hooks remain consistent, but implementation details have evolved. Here's what you need to know:

```typescript
// Example of modern react hooks pattern
function useModernPattern() {
// Implementation example
return {
apply: () => {
console.log("Applying modern react hooks pattern");
}
};
}
```

⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Code examples do not demonstrate React hooks despite the guide's title and purpose.

The blog post is titled "React hooks in 2026: A Practical Guide," but neither code example actually uses React hooks. The first example (lines 24-34) defines useModernPattern() with a hook-like name but contains no React hook logic. The second example (lines 53-71) is a standard React component without any hook usage (no useState, useEffect, useCallback, useMemo, custom hooks, etc.). This creates a misleading expectation for readers seeking practical hook patterns.

To align with the title and provide genuine value, replace these examples with actual React hooks implementations—such as useState for state management, useEffect for side effects, or custom hooks for reusable logic patterns.

💡 Example: Replace with an actual React hooks example

The first example could demonstrate a custom hook:

// Real custom hook example
function useCounter(initialValue = 0) {
  const [count, setCount] = useState(initialValue);
  const increment = useCallback(() => setCount(c => c + 1), []);
  const decrement = useCallback(() => setCount(c => c - 1), []);
  return { count, increment, decrement };
}

// Usage in a component
function CounterComponent() {
  const { count, increment, decrement } = useCounter(0);
  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={increment}>+</button>
      <button onClick={decrement}>-</button>
    </div>
  );
}

The second example could demonstrate useEffect and useState together:

// Real example with hooks
interface UserData {
  name: string;
  id: number;
}

function UserProfile({ userId }: { userId: number }) {
  const [user, setUser] = useState<UserData | null>(null);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    fetchUser(userId).then(data => {
      setUser(data);
      setLoading(false);
    });
  }, [userId]);

  if (loading) return <div>Loading...</div>;
  return <div>{user?.name}</div>;
}

In `@content/blog-post-2026-06-22/react-hooks-in-2026-a-practical-guide.mdx`
around lines 24 - 34, The `useModernPattern()` function on lines 24-34 and the
second code example on lines 53-71 do not contain actual React hooks despite the
blog post title "React hooks in 2026: A Practical Guide." Replace the
`useModernPattern()` implementation with a genuine custom hook that uses React
hooks like `useState` and `useCallback` to demonstrate real hook patterns.
Similarly, update the second example to demonstrate actual hook usage such as
`useState` for state management and `useEffect` for side effects instead of just
showing a standard component without any hook logic.


### 2. Common Pitfalls to Avoid

- **Ignoring performance**: Always measure before optimizing
- **Over-engineering**: Start simple, add complexity when needed
- **Not following conventions**: Stick to established patterns in your codebase

### 3. Best Practices

1. Start with the basics before moving to advanced patterns
2. Test your implementations thoroughly
3. Document your code for future reference
4. Keep performance in mind throughout development

## Real-World Example

Here's a practical example you can adapt for your projects:

```typescript
// Real-world application example
interface Props {
data: string[];
onUpdate: (value: string) => void;
}

function Component({ data, onUpdate }: Props) {
return (
<div>
{data.map(item => (
<button key={item} onClick={() => onUpdate(item)}>
{item}
</button>
))}
</div>
);
}
```

## Conclusion

React hooks is an essential skill for modern frontend developers. By understanding these patterns and implementing them in your projects, you'll build better applications that are more maintainable and performant.

Start with the basics, practice regularly, and gradually incorporate more advanced techniques into your workflow. The key is consistency and continuous learning.
