Question 1: How does data loading work in Remix?

You can gauge whether the developer knows how Remix handles loading data (using LoaderFunction and useLoaderData) compared with other React frameworks. A great answer—loading data from the GitHub API—might look like this:

This answer is ideal in TypeScript. A good answer in plain JavaScript is also valid, and you can discuss why the TypeScript version has advantages.

Question 2: Say you were building a webpage analytics dashboard using Remix. What might the routes structure look like?

This checks understanding of nested routes in Remix and how page components interact. Here’s an example file-tree for such an app:

You’d render each child route within its parent using <Outlet>:

A great answer includes both the file-tree and the <Outlet> usage; if it’s missing, steer the candidate toward discussing how routes render.

Question 3: Add an error boundary to one of the routes above. How does a user trigger that error?

This tests whether the developer has thought through error handling in Remix. A strong answer explains the flow:

“Imagine the dashboard loads two child routes: a bar chart and a line chart. If the line chart’s data fetch fails, we wrap that route’s module in an ErrorBoundary. Here’s how we’d add it to LineChartRoute.tsx:”

View ErrorBoundary example

An OK answer still shows the code; follow-up questions can explore handling errors for the entire dashboard.

Question 4: What is Progressive Enhancement?

Progressive enhancement is central to Remix: core page content and navigation must work without JavaScript or network data, then “enhance” as resources load.

Great answer:
“Progressive enhancement prioritizes basic functionality and content for all users—regardless of device or network quality—then layers on additional features and data as available. This ensures accessibility, reliability, and performance for everyone.”

A good answer might only mention a “spinner-free” loading experience; prompt deeper discussion around accessibility and content-first principles.

Question 5: Why does Remix use the Fetch API?

Remix’s choice of the Fetch API has two key reasons:

1. Asynchronous, non-blocking requests
   Fetch sends requests without blocking the event loop. Remix’s performance hinge—handling user input and rendering while data loads—relies on this non-blocking behavior and Promise-based callbacks.

2. Built-in web standard
   Fetch works out of the box in modern browsers and on the edge (no extra libraries needed). Remix leverages web standards (not Node-only APIs) so you can deploy to edge runtimes like Cloudflare Workers or Deno Deploy.
