What is authkit-remix-cloudflare?

AuthKit Remix Cloudflare is a package that adds user login, signup, and session management to web apps built with Remix and deployed on Cloudflare. It handles the plumbing for authentication through a service called WorkOS, so you can offer secure sign-in and sign-out flows without building them from scratch. The original WorkOS library for Remix was designed for traditional server environments and relied on reading configuration in a way that Cloudflare's runtime doesn't support. This fork fixes that by adapting how environment variables are accessed so everything works properly on Cloudflare. Beyond that fix, it provides the same core features: a callback route that catches users after they authenticate through WorkOS, helpers to fetch user profile data inside your app pages, a way to require authentication on specific routes, a sign-out function, and access to the underlying access token if you need to call other APIs on the user's behalf. A developer building a Remix app hosted on Cloudflare would use this when they need real user accounts. For example, if you are building a dashboard app where each user sees their own data, you'd use the library to redirect visitors to a WorkOS-hosted login page, then get back a user object containing details like their name. You can also lock down specific pages so unauthenticated visitors are automatically sent to sign in, and retrieve an access token to pass along to your backend API. The project is straightforward in scope: it exists primarily because the upstream library didn't play nice with Cloudflare's workers runtime. The author also added a small custom helper, getSessionFromRequest, for retrieving session data directly from a request and context, which isn't in the original WorkOS version.
