Augmenting load context using session data in Cloudflare template

[ramiroazar]

We're using Cloudflare Pages and augmenting the load context, but need to access session data in getLoadContext.

https://remix.run/docs/en/main/guides/vite#augmenting-load-context

Since getSession is async, making getLoadContext async and using await in functions/[[path]].ts and vite.config.ts seems to work in development, but fails during the build with the following error.

This require call is not allowed because the transitive dependency "[[path]].ts" contains a top-level await

For extra context, I'm trying to follow the instructions below and have got everything working, except for previews which require session data.

The instructions above assume a server.ts file like the ones below, but the Cloudflare template from Remix doesn't include one.
