Authentication for React Router or Remix Applications
Blog post from Clerk
In 2024, Remix and React Router merged, and Remix v3 was released as React Router v7 in December, becoming the recommended framework for new applications. This guide focuses on integrating authentication into a React Router v7 application using Clerk, which offers features like email and one-time code authentication, Google and GitHub sign-ins, and role-based organizations. Clerk provides prebuilt UI components and server-side rendering support with its @clerk/react-router SDK. While Clerk is considered the best-fit authentication provider for React Router v7 or Remix v2 apps, the guide also discusses alternatives like Supabase Auth, Auth0, and WorkOS, each with specific benefits and trade-offs. The text details setting up authentication, protecting routes, handling server-side rendering, and managing user sessions in React Router environments. It also covers deployment considerations for platforms like Vercel and Cloudflare, as well as production best practices for security and performance.
