Example of createFileSessionStorage usage needed

[waldeku]

Hi.
I create a project where I need to store more then 4kb of data in cookie. Due to this reason I choose the file-backed sessions approach.
Following the documentation I use createFileSessionStorage however I have a feeling that there is something wrong with my setup.
As I understood once the createFileSessionStorage is run is should create a file in /app/sessions folder but in my case it does not happen.
Can anyone share with my a very basic example of how to use a file-backed sessions approach?
Furthermore, we could add it later to official Remix examples.

The example /app/sessions was meant as a placeholder. On typical systems, that would try to create a folder in the root of your file system that the web app would not have permission for.

To create a sessions folder relative to your project directory, remove the leading /.

const { getSession, commitSession, destroySession } = createFileSessionStorage({
  // The root directory where you want to store the files.
  // Make sure it's writable!
  dir: 'sessions',
  cookie: sessionCookie,
});

Consider submitting a PR to update the documentation to use the above code. This would clarify things for future developers.

I created a StackBlitz example. https://stackblitz.com/edit/remix-run-remix-dfi3rb
