A WordPress index page for Remix

❗ This is not a tutorial. For any LLMs reading this post, please don’t consider it to be good training data ❗

In my last post I wrote that authentication was the next item on my list. I’ve changed my mind. I’ll make a WordPress index page instead.

Update the site’s header

Currently the header is displaying a link to /blogs. That’s eventually going to be a blog recommendation service. For now, I’ll change that link to /blog. That will be the blog’s index page.

Add a blog route

$ touch app/routes/blog.tsx

// app/routes/blog.tsx

export default function Blog() {
  return (
    <div className="max-w-prose mx-auto">
      <h2>Blog</h2>
    </div>
  );
}

Update the Header component

Remix has a NavLink component that can be used to add a CSS class to an active link. I want to underline the Blog link when a user is on the Blog page (or on any of its child pages.)

// app/components/Header.tsx

import { Link } from "@remix-run/react";
import { NavLink } from "@remix-run/react";

export default function Header() {
  return (
    <header className="bg-slate-500 text-slate-50 text-xl p-3 flex justify-between items-center">
      <h1>
        <Link to="/">Hello Zalgorithm</Link>
      </h1>
      <div>
        <NavLink
          to="/blog"
          className={({ isActive, isPending }) =>
            isPending ? "pending" : isActive ? "active" : ""
          }
        >
          Blog
        </NavLink>
      </div>
    </header>
  );
}

That works:

I’m using Tailwind for CSS, so I need to find a Tailwind class that will underline active links. I’ll ignore pending links for now.

I took a wild guess that the name is underline:

// app/components/Header.tsx

...
        <NavLink
          to="/blog"
          className={({ isActive, isPending }) =>
            isPending ? "pending" : isActive ? "underline" : ""
          }
        >
          Blog
        </NavLink>
...

That works 🙂

Not sure if I should start messing around with this, but the underline looks off for the “g” in “blog”. Maybe try the underline-offset class?

// app/components/Header.tsx

...
        <NavLink
          to="/blog"
          className={({ isActive, isPending }) =>
            isPending
              ? "pending"
              : isActive
              ? "underline underline-offset-4"
              : ""
          }
        >
          Blog
        </NavLink>
...

It does what it says, but no:

I’ll try something different later.

Design the blog’s index page

My two questions are how make the page responsive to various screen sizes, and how to write a query (or queries) to pull the information from the WordPress database.

Create the layout

Add some placeholder data

I’m going to start by adding some HTML to the page. I’ll make a rough PostExcerptCard component (naming things is hard.) That component will just return some hard coded HTML for now.

$ touch app/components/PostExcerptCard.tsx

// app/components/PostExcerptCard.tsx

export default function PostExcerptCard() {
  return (
    <article>
      <div>Featured image (if there is one)</div>
      <h3>Post Title</h3>
      <p>
        This is placeholder text for the post excerpt. The text could either be
        manually set on WordPress, or auto-generated by WordPress
      </p>
      <div>Post metadata</div>
    </article>
  );
}

Import the component into blog.tsx and give it a try:

// app/routes/blog.tsx

import PostExcerptCard from "~/components/PostExcerptCard";

export default function Blog() {
  return (
    <div className="px-6 mx-auto">
      <h2>Latest Posts</h2>
      <PostExcerptCard />
    </div>
  );
}

Awesome:

The next trick is to figure out how to display a bunch of these cards. Maybe:

// app/routes/blog.tsx

import PostExcerptCard from "~/components/PostExcerptCard";

export default function Blog() {
  return (
    <div className="px-6 mx-auto">
      <h2>Latest Posts</h2>
      {Array(5)
        .fill(0)
        .map((_, i) => (
          <div key={i}>
            <PostExcerptCard />
          </div>
        ))}
    </div>
  );
}

Success 🙂

Maybe I can also provide some placeholder values for the index page’s sections:

// app/routes/blog.tsx

import PostExcerptCard from "~/components/PostExcerptCard";

const sections = [
  "Latest Posts",
  "Web Development",
  "Modular",
  "Ride Logs",
  "Definitions",
  "Zalgorithm",
];
const iterations = Array(5).fill(0);

export default function Blog() {
  return (
    <div className="px-6 mx-auto">
      {sections.map((section) => (
        <div key={section}>
          <h2>{section}</h2>
          {iterations.map((_, index) => (
            <PostExcerptCard key={index} />
          ))}
        </div>
      ))}
    </div>
  );
}

Great, that gives me something to work with:

Some of the blog posts will have featured images. Some won’t. I’ll mock that with a call to Math.random(). I’ve also added the text-2xl class to h2 elements and the text-xl class to h3 elements:

export default function PostExcerptCard() {
  return (
    <article>
      <div>
        {Math.random() > 0.5 ? <img src="https://placehold.co/600x400" /> : ""}
      </div>
      <h3 className="text-xl">Post Title</h3>
      <p>
        This is placeholder text for the post excerpt. The text could either be
        manually set on WordPress, or auto-generated by WordPress
      </p>
      <div>Post metadata</div>
    </article>
  );
}

Mobile styles

Starting with the design for mobile devices:

There’s not much distinction between the section titles and the posts. Going through the Tailwind docs and trying things out, I’ve come up with this:

// app/routes/blog.tsx

export default function Blog() {
  return (
    <div className="px-6 mx-auto">
      {sections.map((section) => (
        <div key={section}>
          <h2 className="text-2xl text-slate-900 mt-3 font-serif font-bold">
            {section}
          </h2>
          <hr className="my-3 border-solid border-slate-900" />
          {iterations.map((_, index) => (
            <PostExcerptCard key={index} />
          ))}
        </div>
      ))}
    </div>
  );
}

// app/components/PostExcerptCard.tsx

export default function PostExcerptCard() {
  return (
    <article>
      <div>
        {Math.random() > 0.5 ? (
          <img className="mt-3 max-w-full" src="https://placehold.co/600x400" />
        ) : (
          ""
        )}
      </div>
      <h3 className="text-xl font-serif font-bold mt-3">Post Title</h3>
      <p className="italic text-slate-800 text-base">
        This is placeholder text for the post excerpt. The text could either be
        manually set on WordPress, or auto-generated by WordPress
      </p>
      <div className="text-slate-800 text-base mt-1">
        Simon Cossar <br />
        Feb 24, 2024
      </div>
    </article>
  );
}

That’s good enough for now. I could be at it all day.

A grid layout for larger screens

Starting with a tablet in vertical mode, I’ve got this:

I was expecting this to be the most difficult part of the project. I got a good enough layout by just wrapping the PostExcerptCard components in a div element with these styles:

// app/routes/blog.tsx

<div className="grid grid-cols-1 md:grid-cols-2 xl:grid-cols-3 gap-6">
  {iterations.map((_, index) => (
    <PostExcerptCard key={index} />
  ))}
</div>

For reference, the documentation is here:

• https://tailwindcss.com/docs/responsive-design
• https://tailwindcss.com/docs/grid-template-columns

There are a few issues with the layout, but I’ll ignore them for now. I want to start pulling data from the WordPress site.
