# Loading Routes Within Routes in Remix: A Guide to Reusable Components

Remix is a powerful framework that simplifies building dynamic web applications by enhancing the way we manage data loading, routing, and rendering. However, for those who come from a more traditional web development background, such as ASP.NET MVC, adapting to Remix's approach can be a challenge. In this article, we’ll explore how to effectively load routes within routes to create reusable components in Remix, particularly focusing on an API check functionality that is both independent and reusable across various routes.

## Understanding the Problem

As a developer transitioning from ASP.NET MVC, you might want to create components that can be reused across different routes while still maintaining the context of data loading and authentication. In your case, you have two primary routes:

- **/apicheck**: This route performs an API check that requires user authentication.
- **/dashboard**: This route should display the API check component.

The challenge arises because when you call `Apicheck` directly in the `Dashboard` component, the loader function of `Apicheck` does not execute as it would when visiting the `/apicheck` route. This is due to Remix's architecture, which triggers loaders only on route changes.

## Solution: Using Loaders with Reusable Components

To achieve your goal, there are a few strategies you can implement. Here’s a refined approach based on community insights and suggestions.

### Step 1: Refactor the API Check Logic

Instead of embedding the `Apicheck` component directly into the `Dashboard`, create a shared loading function that can be imported into both components.

#### apicheck.tsx

```tsx
import { json } from "@remix-run/node";
import { useLoaderData } from "@remix-run/react";
import { authenticator } from "../auth";

export const loader = async ({ request }) => {  
    console.log('apicheck loader called');
    
    const user = await authenticator.isAuthenticated(request, {
      failureRedirect: "/account/login",
    });

    let message = 1; // Placeholder message; adjust as needed
    return json({ message });
};

export default function Apicheck() {
    console.log("Apicheck component rendered");
    const { message } = useLoaderData();

    return (
      <div>
        {message}
      </div>
    );
}

Step 2: Use the Loader in Dashboard

Next, modify your Dashboard component to call the apicheck loader and pass the necessary data to the Apicheck component.

dashboard.tsx

import { json } from "@remix-run/node";
import { useLoaderData } from "@remix-run/react";
import { authenticator } from "../auth";
import Apicheck from "./apicheck";

export const loader = async ({ request }) => {  
    console.log('Dashboard loader called');
    
    const user = await authenticator.isAuthenticated(request, {
      failureRedirect: "/account/login",
    });

    // Load data for Apicheck directly
    const apicheckData = await Apicheck.loader({ request });

    return { user, apicheckData };
};

export default function Dashboard() {
    console.log("Dashboard component rendered");
    const { apicheckData } = useLoaderData();

    return (
      <div>
        <h1>Dashboard</h1>
        <Apicheck initialData={apicheckData} /> {/* Pass loader data as prop */}
      </div>
    );
}

Step 3: Pass Props to Apicheck

Now, modify the Apicheck component to accept props and use them instead of fetching data on its own. This ensures that the loader is called from the Dashboard.

export default function Apicheck({ initialData }) {
    console.log("Apicheck component rendered");
    return (
      <div>
        {initialData.message}
      </div>
    );
}

Conclusion

With this approach, you’ve successfully created a reusable Apicheck component that leverages the loader function from the Dashboard. This architecture not only follows Remix's data loading principles but also enhances component reusability—making it easier to manage authentication and data fetching across your application.

Additional Considerations

  • Error Handling: Always consider how to handle errors from the loader functions to provide meaningful feedback to users.
  • Testing: Given the complexity of authentication, implement unit tests to ensure your components behave as expected.
  • SEO Optimization: Ensure your routes return appropriate meta tags and structured data for search engines when rendering dynamic content.

By following these principles and strategies, you can effectively utilize Remix’s capabilities to build scalable, maintainable web applications that feel familiar, even for developers coming from different frameworks like ASP.NET MVC.
