ChangelogSingleItem Component

The ChangelogSingleItem component is a React component designed to display detailed information about a single changelog entry. It's built for use in Next.js applications and supports MDX content rendering.

Importing the Component

To use the ChangelogSingleItem component in your Next.js application, import it as follows:

import ChangelogSingleItem from '@/components/ChangelogSingleItem';

Basic Usage

Here's a basic example of how to use the ChangelogSingleItem component:

import { Changelog } from 'contentlayer/generated';

const changelogData: Changelog = {
  // ... changelog data
};

<ChangelogSingleItem data={changelogData} />;

Props

The ChangelogSingleItem component accepts the following prop:

Prop	Type	Description
data	Changelog	An object containing the changelog entry data

The Changelog type is expected to have the following properties:

• version: The version number of the changelog entry
• title: The title of the changelog entry
• date: The date of the changelog entry
• description: A brief description of the changelog entry
• body: An object containing the MDX content of the changelog entry

Functionality

The ChangelogSingleItem component provides the following functionality:

1. Displays detailed information about a single changelog entry, including title, version, date, and description.
2. Renders MDX content for the changelog entry body.
3. Provides a link to view all changelogs.

UI Components

The component uses several UI components:

• Card, CardContent, CardDescription, CardHeader, CardTitle: For structuring the changelog entry layout
• Badge: For displaying the version number
• CustomButton: For the "See All Changelogs" link
• MoveLeftIcon: From the lucide-react library for the back arrow icon

MDX Rendering

The component uses the useMDXComponent hook from next-contentlayer/hooks to render the MDX content of the changelog entry:

const Component = useMDXComponent(data?.body?.code);

This allows for rich, formatted content within the changelog entry.

Styling

The component uses Tailwind CSS for styling:

• The Card component is centered with a maximum width and no border.
• The title uses large, bold text.
• The version badge uses a secondary variant.
• The date is displayed with muted text.
• The MDX content area has vertical spacing between elements.

Customization

To customize the ChangelogSingleItem component:

1. Modify the Tailwind classes to adjust the layout and styling.
2. Replace the UI components (Card, Badge, etc.) with your own custom components if needed.
3. Adjust the date formatting to match your preferred style.

Accessibility

To improve accessibility:

1. Ensure that the MDX content follows accessibility best practices.
2. Consider adding ARIA labels to the "See All Changelogs" button for better context.

Best Practices

1. Ensure that the Changelog data passed to the component is complete and correctly formatted.
2. Keep MDX content concise and well-structured for easy reading.
3. Consider adding keyboard navigation support for moving between changelog entries.

Example Usage

Here's an example of how you might use the ChangelogSingleItem component in a Next.js page:

import { getChangelogBySlug } from '@/lib/changelogs';
import ChangelogSingleItem from '@/components/ChangelogSingleItem';

export default function ChangelogPage({ params }) {
  const changelog = getChangelogBySlug(params.slug);

  return (
    <div className='container mx-auto py-8'>
      <h1 className='text-3xl font-bold mb-6'>Changelog</h1>
      <ChangelogSingleItem data={changelog} />
    </div>
  );
}

export async function getStaticProps({ params }) {
  const changelog = getChangelogBySlug(params.slug);
  return { props: { changelog } };
}

export async function getStaticPaths() {
  const changelogs = getAllChangelogs();
  const paths = changelogs.map((changelog) => ({
    params: { slug: changelog.slug },
  }));
  return { paths, fallback: false };
}

This example demonstrates how to use the ChangelogSingleItem component within a dynamic page that displays a specific changelog entry based on the URL slug.
