How do I read session data outside of the asynclocalstorage context?

Is there some function I can pass a request into and get the session data out? I need to get an API token from the session to use in a proxy middleware in my express server running the whole app.

Getting Started Example's start command not working

How do I run a server function during SSR?

I'm using TS Start with React Query (based on this example https://tanstack.com/start/latest/docs/framework/react/examples/start-basic-react-query) and I want to get a theme cookie during SSR so I don't get a flash of inaccurate color theme. It looks like if I put the server function in the loader it works but doesn't update and if I put it in a useQuery it updates dynamically but flashes a null / system theme first. I could wire up the loader to pass initial data to the query client but I want to make sure I'm not making it too complicated....

Kill the Start process?

If we're running Start in a docker container and want to have the container die if something is broken in the server (i.e. some required dependency cannot be constructed), is process.exit(1) in the server.ts file the right way to do this?

how to handle circular dependency breaking hmr?

I've noticed that hmr does not work properly when using server functions and react query running the start-basic-react-query example and changing anything in posts.route for example will trigger a hard refresh because of the way things get imported, running with --debug hmr produces this output

vite:hmr circular imports detected: /src/routes/posts.route.tsx -> /src/utils/posts.tsx -> /node_modules/@tanstack/react-start/dist/esm/client.js?v=0794880d -> /node_modules/@tanstack/react-start-client/dist/esm/index.js?v=0794880d -> /node_modules/@tanstack/start-client-core/dist/esm/client/index.js?v=0794880d -> /node_modules/@tanstack/start-client-core/dist/esm/client/hydrateStart.js?v=0794880d -> /src/router.tsx -> /src/routeTree.gen.ts -> /src/routes/posts.route.tsx

any suggestions on how to handle this?...
