React asynchronous hooks are a powerful tool for managing asynchronous code in a React application. They provide a convenient and organized way to handle different states of an asynchronous function and ensure that the component only updates when necessary. In this blog post, we will take a look at some examples of using asynchronous hooks in a React application.

One of the most commonly used asynchronous hooks is the "useEffect" hook. This hook allows a component to perform side effects after a render, such as fetching data from an API. In the following example, we use the "useEffect" hook to fetch a list of users from an API and update the component's state with the response data.

```js
import { useState, useEffect } from 'react';

function Users() {
  const [users, setUsers] = useState([]);
  
  useEffect(() => {
    async function fetchUsers() {
      const response = await fetch('/api/users');
      const data = await response.json();
      setUsers(data);
    }
    fetchUsers();
  }, []);
  
  return (
    <ul>
      {users.map(user => (
        <li key={user.id}>{user.name}</li>
      ))}
    </ul>
  );
}
```
In this example, the "useEffect" hook is called with an asynchronous function that fetches the list of users from the API. The hook is called with an empty array as the second argument, which means that it will only be called on the initial render of the component. This ensures that the component will only fetch the data once, and will not re-fetch the data on subsequent renders.

Another useful asynchronous hook is the "useAsync" hook. This hook takes in an asynchronous function and returns an object with information about the function's status (pending, error, or success) and any returned data. In the following example, we use the "useAsync" hook to handle a button that sends an email when clicked.

```js
import { useAsync } from 'react-async';

function EmailButton() {
  const sendEmail = async () => {
    // Send email code goes here
  };
  const { isPending, error, run } = useAsync({
    promiseFn: sendEmail
  });
  
  if (isPending) return <p>Sending email...</p>;
  if (error) return <p>Error: {error.message}</p>;
  
  return (
    <button onClick={run}>Send Email</button>
  );
}
```
In this example, the "useAsync" hook is called with the "sendEmail" function as the "promiseFn" argument. This hook returns an object with information about the function's status and any returned data. The component then uses this information to render the appropriate content, such as displaying a loading message while the email is being sent, or an error message if there was a problem sending the email.

As you can see, React asynchronous hooks provide a convenient and organized way to manage asynchronous code in a React application. They make it easy to handle different states of an asynchronous function and ensure that the component only updates when necessary. If you are working with asynchronous code in your React application, I highly recommend using asynchronous hooks to make your code cleaner and more maintainable.

We use [MDX](https://mdxjs.com) for content editing. MDX lets you write content in Markdown and seamlessly embed interactive components.

The `@reflexjs/mdx` package ships with a library of components such as image galleries, video embed, callouts and much more.

## Typography

Riche que puisque protéger arbre rayon ami. Parce Que bureau mort couleur pourquoi. Conscience santé début devoir sien grâce désert peu.

# Heading One

Occur hour especially concern business. Piece movie indeed so wait week. Under stop trade personal. [Unde harum natus](https://reflexjs.org) nisi est. Quibusdam explicabo quibusdam vel. Mollitia nostrum laborum fuga facere minus quod.

## Heading Two

Inspired by [stale-while-revalidate](https://tools.ietf.org/html/rfc5861), background regeneration ensures traffic is served uninterruptedly, always from static storage, and the newly built page is pushed only after _it's done generating_.

Choix effacer parvenir _grave entretenir_. Peau soir attendre fortune long. Champ double falloir prévenir froid.

### Heading Three

## Lists

Unlike traditional SSR, Incremental Static Regeneration ensures you retain the benefits of static:

### Unordered List

- No spikes in latency. Pages are served consistently fast.
- Pages never go offline. If the background page re-generation fails, the old page remains unaltered.
- Low database and backend load. Pages are re-computed at most once concurrently.

Both incremental features (adding pages and lazily updating them), as well as preview mode, are now stable and already fully supported by both next start and the Vercel edge platform out of the box.

### Ordered List

1. No spikes in latency. Pages are served consistently fast.
2. Pages never go offline. If the background page re-generation fails, the old page remains unaltered.
3. Low database and backend load. Pages are re-computed at most once concurrently.

### Nested List

1. No spikes in latency. Pages are served consistently fast.

   - Debra Oliver
   - Gabriel Cortes Blazquez

2. Low database and backend load. Pages are re-computed at most once concurrently.

   - Inga Weiß-Förster
   - Ruben Camacho Expósito

3. Pages never go offline.

## Code

Smart has support for code blocks with syntax highlighting, file names, line numbers and line highlighting.

### Inline Code

For inline code blocks, wrap your code in backticks: \`const name = "reflexjs"\`. This will be rendered as follows: `const name = "reflexjs"`.

### Code blocks

For code blocks that allows multiple lines, syntax highlighting, line numbers and line highlighting, use triple backticks for code fencing: ` ``` `.

````
```jsx
export function Footer({ copyright, ...props }: FooterProps) {
  return (
    <section {...props}>
      <p variant="text.sm" textAlign="center" my="0">
        {copyright}
      </p>
    </section>
  )
}
```
````

```jsx
/** @jsx jsx */
import { jsx } from "reflexjs"

export function Footer({ copyright, ...props }: FooterProps) {
  return (
    <section {...props}>
      <p variant="text.sm" textAlign="center" my="0">
        {copyright}
      </p>
    </section>
  )
}
```

### Line Numbers

Use `showLineNumbers` to add line numbers.

````
```js showLineNumbers
export async function getStaticProps() {
  return {
    props: await getDataFromCMS(),
    // we will attempt to re-generate the page:
    // - when a request comes in
    // - at most once every second
    revalidate: 1,
  }
}
```
````

```js showLineNumbers
export async function getStaticProps() {
  return {
    props: await getDataFromCMS(),
    // we will attempt to re-generate the page:
    // - when a request comes in
    // - at most once every second
    revalidate: 1,
  }
}
```

### Title

Use `title=` to add a title to the code block. This is useful for displaying relevant file name or path.

````
```js title=path/to/next.config.js
module.exports = {
  basePath: "/docs",
}
```
````

```js title=path/to/next.config.js
module.exports = {
  basePath: "/docs",
}
```

### Line Highlighting

Use `// highlight-start` and `// highlight-end` to highlight multiple lines. For single line highlighting use `// highlight-line`.

````
```tsx title=pages/[...slug].tsx showLineNumbers=true
export async function getStaticProps() {
  // highlight-start
  // Fetch all MDX posts.
  const posts = await getAllMdxNodes("post")
  // highlight-end

  return {
    props: {
      posts,
    },
    revalidate: 1, //highlight-line
  }
}
```
````

```tsx title=pages/[...slug].tsx showLineNumbers=true
export async function getStaticProps() {
  // highlight-start
  // Fetch all MDX posts.
  const posts = await getAllMdxNodes("post")
  // highlight-end

  return {
    props: {
      posts,
    },
    revalidate: 1, // highlight-line
  }
}
```

### Diff

You can also show diff using the `+` for line additions and `-` for deletions.

````
```diff
+ this line was added
- this line was deleted
```
````

```diff
+ this line was added
- this line was deleted
```

## Images

To add images to your content, place them in the `public/images` directory and then use them in Markdown:

```md
![Alt text](/images/placeholder.jpg)
```

![Alt text](/images/placeholder.jpg)

### With Caption

If you need to add a caption to your images, use the following code:

```html
<figure>
  <img src="/images/placeholder.jpg" alt="Alt text" />
  <figcaption>Caption for the image</figcaption>
</figure>
```

<figure>
  <img src="/images/placeholder.jpg" alt="Alt text" />
  <figcaption>Caption for the image</figcaption>
</figure>
