SvelteKit demo app not working

[peterlerche]

Desperate to find a solution to #38 I made a clean installation of Svelte demo app using the guide on https://bun.sh/guides/ecosystem/sveltekit.

When browsing the demo app, I get a lot of the below faults.

709 | });
710 | };
711 | var get_origin = function(headers) {
712 | const protocol = protocol_header && headers.get(protocol_header) || "https";
713 |
714 | const host = headers.get(host_header);
^
TypeError: Invalid header name: ''
at get_origin (/my-app/build/index.js:714:15)
at ssr (/my-app/build/index.js:682:23)

Why do we see these faults, is Bun changing their internals or is svelte-adapter-bun out of sync with the newer version of bun?

All help, ideas, and guidance will be appreciated.

I have the same problem in a "real" application, not just the demo.

Until this has been merged, it seems a fix is to set the following env variables:

PROTOCOL_HEADER=x-forwarded-proto
HOST_HEADER=x-forwarded-host

I've forked this repo and published my own NPM package. The fix for this issue is already merged into my fork and I plan to keep it updated. Anyone else having this issue is free to use it if you'd like:

bun add @catdadcode/svelte-adapter-bun -D

https://github.com/catdadcode/svelte-adapter-bun

I've also added signal event handling to the fork. Previously if you ran your Svelte app in a Docker container then killing the container would take 10+ seconds before Docker would force kill it. The resulting build/ app from this adapter now has proper process signal handling and will gracefully shutdown immediately upon receiving any of SIGTERM, SIGINT, SIGQUIT, SIGSTOP, or SIGKILL.
