// Custom production server: wraps adapter-node's generated request handler in
|
|
// a plain http.Server so we can also intercept WebSocket upgrade requests,
|
|
// which SvelteKit itself has no hook for (see src/lib/server/core/ws-handler.ts).
|
|
//
|
|
// `.env` is not auto-loaded here (SvelteKit's own adapter-node doesn't in
|
|
// production either) — run with `node --env-file=.env server.js` locally, or
|
|
// provide OPENAI_API_KEY / REALTIME_TOKEN_SECRET via your deployment's real
|
|
// secret mechanism.
