Remix

Overview​

Remix is a full-stack React framework centered on web fundamentals: nested routes, loaders/actions tied to routes, progressive enhancement, and excellent handling of forms, errors, and caching at the edge. It merges with React Router in newer unified releases—follow current docs for your installed major version.

Key concepts​

  • Route modules — loader for GET data, action for mutations.
  • Nested routing — Shared layouts with independent data loading.
  • Forms — Prefer HTML forms + actions over client-only state when possible.
  • Error boundaries — Route-level error UI.
  • Deployment — Node, serverless, or edge adapters.

Mutation with action (conceptual)​

Sample: route module sketch​

import type { ActionFunctionArgs } from '@remix-run/node';
import { Form } from '@remix-run/react';

export async function action({ request }: ActionFunctionArgs) {
  const form = await request.formData();
  const name = String(form.get('name') ?? '');
  if (!name) return { errors: { name: 'Required' } };
  // persist...
  return redirect('/');
}

export default function Page() {
  return (
    <Form method="post">
      <input name="name" />
      <button type="submit">Save</button>
    </Form>
  );
}
