The production image is now a single Go binary that serves both the JSON/WebSocket API under /api and the Svelte dashboard at /. - New internal/webui package embeds a dist/ subdir via //go:embed. A placeholder index.html is committed so `go build` works on a fresh checkout; anything else in dist/ is regenerated per build and gitignored. - httpapi.Server.Handler mounts the embed.FS at / with SPA-style fallback: unknown non-/api paths serve index.html so client-side routes survive a reload. /api/* is carved out explicitly so POSTs or typos never accidentally shadow API semantics with HTML. - api/Dockerfile grows a node:22 builder stage that runs `npm ci && npm run build`, and the Go stage copies ui/dist/ into internal/webui/dist/ before `go build`. Build context moves to the repo root (docker-compose + `make api` both updated) so the Dockerfile can see both api/ and ui/. With this in place, `make up` brings the whole stack online at http://localhost:8080 — API under /api, dashboard at /. The Vite dev server on :5173 with the /api proxy is still available via `make ui-dev` for hot-reload development.

# kamado-api build

#
|
|
# Stage 1 (ui): Build the Svelte dashboard to ui/dist.
|
|
# Stage 2 (go): Build the Go binary, embedding the UI via //go:embed.
|
|
# Stage 3 (run): Minimal debian with tini and the static binary.
|
|
#
|
|
# The build context for this Dockerfile is the ./api directory by
|
|
# default, which is fine for stage 2. But stage 1 needs the ui/
|
|
# directory from the repo root. docker-compose sets `context: .` at
|
|
# the repo root and `dockerfile: api/Dockerfile` to make both visible;
|
|
# for plain `docker build ./api`, set --build-context repo=..
