Running `pnpm dev` alone gave ECONNREFUSED on every request, because nothing
was listening on :7788. Two separate causes:
- the backend simply was not running, and
- Vite bound [::1]:5173 while the proxy target was "localhost", which Node
resolves to ::1 first. The Go server binds IPv4, so even with the backend up
the proxy could fail before falling back.
- vite.config.ts: proxy target is now 127.0.0.1 explicitly and overridable via
VELLUM_API; server.host is true so both stacks are served.
- scripts/dev.sh + `make dev`: builds the backend, waits for /healthz, starts
Vite, and stops the backend on exit. Ctrl-C tears down both.
- README documents that running Vite alone needs the backend already up.
The frontend the app needs to be usable at all.
- web/: Svelte 5 + Vite + TypeScript SPA. Login, app shell with per-type nav,
library list/create/scan/delete, item grid with covers, admin user
management, and an epub.js reader that syncs progress.
- Reader resumes by spine index — an integer — which is why the polymorphic
progress table needs no text column.
- Session state uses classic stores in a plain .ts module rather than runes in
a .svelte.ts module, avoiding special module resolution.
- Embedding: web/embed.go embeds web/dist. A committed .gitkeep keeps the
directive valid before the frontend is built, so `go build ./...` never
fails. Unknown non-API paths serve index.html for client routes; /api/* and
/healthz always return JSON and never fall back to HTML.
- Dockerfile builds the UI in a node stage and overlays dist into the Go stage.
- pnpm 12 needs allowBuilds in pnpm-workspace.yaml; esbuild approved, the two
unused transitive scripts explicitly denied so install exits 0.
svelte-check: 0 errors, 0 warnings. Verified served: SPA shell at /, route
fallback, hashed asset, and JSON 404 on /api/*.
