Remix in Late 2025: Why I’m Still Obsessed With Loaders

I remember when we used to argue about which React framework was going to “win.” It feels like a lifetime ago. Now, sitting here at the tail end of 2025, the dust has largely settled, and the tools we use have either matured or vanished into the npm abyss.

One tool I haven’t dropped? Remix.

Although, if we’re being pedantic (and as developers, aren’t we always?), it’s barely even a standalone “framework” anymore. Since the great merger with React Router a while back, it’s just… how we write React. But the core philosophy? That hasn’t changed. And honestly, it’s the only thing keeping my sanity intact on these heavy data-dashboard projects I’ve been drowning in lately.

The “News” is That It Just Works

I read a lot of hot takes this week about the latest updates to the ecosystem. People are freaking out about server components again. But here’s the thing: while everyone else is trying to reinvent the wheel with complex caching layers, the Remix pattern of loader + action is still the cleanest mental model I’ve found for moving data across the wire.

It’s not magic. It’s just HTTP. And that’s why it survives.

I was refactoring a legacy dashboard yesterday—something built in the “Wild West” era of 2022—and I realized how much code I didn’t have to write thanks to the latest APIs. No useEffect spaghetti. No global state management boilerplate just to fetch a user profile.

Stop Fetching inside Components

If you’re still fetching data inside your components in 2025, we need to talk. Seriously. It creates those nasty waterfalls that make your app feel like it’s running on a 3G connection in a basement.

The beauty of the Remix model (even now, integrated into the Router) is decoupling the fetch from the render. The server knows what the page needs before the component even mounts. Here is a stripped-down example of how I’m handling data for a “Latest News” widget I built this morning. Note the async nature—it doesn’t block the UI thread, but it blocks the render just enough to prevent layout shift.

import { useLoaderData, json } from "@remix-run/react"; // or react-router in '25
import { getLatestHeadlines } from "~/models/news.server";

// The Loader: Runs on the server (or edge).
// No client-side waterfalls here.
export async function loader() {
  // Pretend this API call takes 50ms or 500ms - the user sees the result instantly
  // once the document arrives, or sees a skeleton if we're streaming.
  const headlines = await getLatestHeadlines({ limit: 5 });
  
  // We return a standard Response object. 
  // It's just web standards all the way down.
  return json({ headlines, lastUpdated: new Date().toISOString() });
}

export default function NewsWidget() {
  // This hook gives us the typed data from the loader.
  // No "isLoading" states to manage manually inside the component logic.
  const { headlines, lastUpdated } = useLoaderData();

  return (
    <div className="news-feed">
      <h2>Market Updates <span className="text-sm text-gray-500">({lastUpdated})</span></h2>
      <ul>
        {headlines.map((item) => (
          <li key={item.id} className="news-item">
            <a href={item.url} target="_blank">
              {item.title}
            </a>
            <span className="badge">{item.source}</span>
          </li>
        ))}
      </ul>
    </div>
  );
}

See that? No fetch calls in the component. No dependency arrays to screw up. You just ask for data, and the route provides it.

Mutations: The Part Everyone Gets Wrong

Reading data is easy. Changing it is where most apps fall apart. I’ve seen so many codebases where a simple form submission triggers a chain reaction of six different re-renders and a manual cache invalidation.

I refuse to do that anymore.

The action pattern is probably my favorite thing about this stack. It mimics the old-school HTML form behavior but upgrades it with JavaScript. When an action completes, Remix automatically revalidates all the data on the page. You don’t tell it to update. It just knows.

Here’s how I handled a “Subscribe” feature for that same news widget. Look at how dumb the component logic is (that’s a compliment).

import { Form, useActionData, useNavigation } from "@remix-run/react";
import { subscribeUser } from "~/models/subs.server";

// The Action: Handles the POST request.
export async function action({ request }) {
  const formData = await request.formData();
  const email = formData.get("email");

  // Basic server-side validation
  if (!email || !email.includes("@")) {
    return json({ error: "That doesn't look like an email." }, { status: 400 });
  }

  try {
    await subscribeUser(email);
    return json({ success: true });
  } catch (err) {
    return json({ error: "Server blew up. Try again." }, { status: 500 });
  }
}

export function SubscribeBox() {
  const actionData = useActionData();
  const navigation = useNavigation();
  
  // "submitting" means the data is in flight.
  // "loading" means the action finished and we're reloading page data.
  const isSubmitting = navigation.state === "submitting";

  return (
    <div className="p-4 border rounded">
      <h3>Get the Daily Brief</h3>
      
      {/* 
        This Form prevents the default browser reload 
        but keeps the semantic HTTP POST semantics.
      */}
      <Form method="post">
        <div className="flex gap-2">
          <input 
            type="email" 
            name="email" 
            placeholder="you@example.com"
            disabled={isSubmitting}
            className="border p-2"
          />
          <button type="submit" disabled={isSubmitting}>
            {isSubmitting ? "Joining..." : "Join"}
          </button>
        </div>
      </Form>

      {/* Error handling right next to the form */}
      {actionData?.error && (
        <p className="text-red-500 mt-2">{actionData.error}</p>
      )}
      
      {actionData?.success && (
        <p className="text-green-500 mt-2">You're in! Check your inbox.</p>
      )}
    </div>
  );
}

Why This Still Matters in 2025

You might be thinking, “Okay, but other frameworks do this now too.” Sure. But the implementation details matter. The way Remix handles the DOM updates during these transitions is surprisingly robust against race conditions.

I ran into a weird edge case last week where a user on a shaky connection hit “Submit” three times. In a standard React app, I’d have to manually debounce that or handle the abort controller. Here? The framework cancels the stale requests automatically. It prioritizes the latest user intent.

We often get distracted by the “New Shiny Thing.” I’m guilty of it too. I spent a whole weekend playing with that new AI-generated UI library everyone is tweeting about. It was fun, but would I put it in production? No way. It broke every time I hit the back button.

Remix (or React Router, whatever label you slap on it today) respects the web. It respects the URL. If I copy a link to a specific state in my app and send it to you, you see what I see. That shouldn’t be a “feature,” it should be the baseline. Yet here we are.

If you haven’t looked at the documentation recently, go check out the new Single Fetch updates. They finally optimized how payloads are bundled, so we aren’t sending unnecessary JSON over the wire. It shaved about 150ms off my largest route’s load time.

Anyway, I’ve got to get back to this dashboard before my PM asks why the charts aren’t updating. Spoiler: it’s the backend API, not the frontend. It’s always the backend.
