Pages Router: Polishing the Post Page

Adding `title` to the Post Page

In pages/posts/[id].js, let’s add the title tag using the post data. You'll need to add an import for next/head at the top of the file and add the title tag by updating the Post component:

// Add this import
import Head from 'next/head';
 
export default function Post({ postData }) {
  return (
    <Layout>
      {/* Add this <Head> tag */}
      <Head>
        <title>{postData.title}</title>
      </Head>
 
      {/* Keep the existing code here */}
    </Layout>
  );
}

Formatting the Date

To format the date, we’ll use the date-fns library. First, install it:

npm install date-fns

Next, create a file called components/date.js and add the following Date component:

import { parseISO, format } from 'date-fns';
 
export default function Date({ dateString }) {
  const date = parseISO(dateString);
  return <time dateTime={dateString}>{format(date, 'LLLL d, yyyy')}</time>;
}

Note: You can view the different format() string options on the date-fns website.

Now, open pages/posts/[id].js, add an import for the Date component at the top of the file, and use it over {postData.date}:

// Add this import
import Date from '../../components/date';
 
export default function Post({ postData }) {
  return (
    <Layout>
      {/* Keep the existing code here */}
 
      {/* Replace {postData.date} with this */}
      <Date dateString={postData.date} />
 
      {/* Keep the existing code here */}
    </Layout>
  );
}

If you access http://localhost:3000/posts/pre-rendering, you should now see the date written as "January 1, 2020".

Finally, let’s add some CSS using the file styles/utils.module.css we added before. Open pages/posts/[id].js, then add an import for the CSS file, and replace the Post component with the following code:

// Add this import at the top of the file
import utilStyles from '../../styles/utils.module.css';
 
export default function Post({ postData }) {
  return (
    <Layout>
      <Head>
        <title>{postData.title}</title>
      </Head>
      <article>
        <h1 className={utilStyles.headingXl}>{postData.title}</h1>
        <div className={utilStyles.lightText}>
          <Date dateString={postData.date} />
        </div>
        <div dangerouslySetInnerHTML={{ __html: postData.contentHtml }} />
      </article>
    </Layout>
  );
}

If you access http://localhost:3000/posts/pre-rendering, the page should now look a little better:

Great work! We’ll polish the index page next and we’ll be done!
