Foodster is a self-hosted dinner log and meal suggester for one household. Stage 1 (eating history) is in development; stage 2 (the suggester) follows once there is enough history to weight against. Replace the PRD's original stack (Nuxt, Postgres, Drizzle, Pico CSS) with Go 1.27, net/http, templ, Datastar and SQLite — one static binary, no Node.js in the build. Sections 3, 4, 5, 9, 10 and 11 are rewritten to match. Record the decisions made while reviewing mockups: - the UI is written in Finnish; PRD, code and comments stay English - access is one shared password over HTTP Basic rather than open on the LAN - images are CalVer vYYYYMMDD-N, built with Podman, run under Docker Compose - registry coordinates live in .env, so no infrastructure detail is committed and the MIT publication option stays open mockups/ holds standalone HTML design studies. log-fi.html is the current one; the others are superseded exploration kept for reference.
Foodster
A self-hosted dinner log and meal suggester for a single household. Record what the family actually ate, and — later — let the app propose seven dinners drawn from that history.
The interface is in Finnish. The code, comments and documentation are in English.
See PRD.md for the full specification.
Status
Stage 1 — eating history: in development. The meal catalog and the daily log come first, because the suggester is worthless until there are a few weeks of real history to weight against.
Stage 2 — the seven-meal suggester — starts once that history exists.
Stack
One static Go binary. No Node.js, no bundler, no separate database server.
| Language | Go 1.27 |
| HTTP | stdlib net/http + http.ServeMux |
| Views | templ, server-rendered |
| Interactivity | Datastar — signals and DOM patching in one ~11 kB script |
| Styling | hand-written CSS, light-dark() for themes |
| Database | SQLite via modernc.org/sqlite (pure Go) |
| Auth | HTTP Basic, one shared household password |
| Runtime image | FROM scratch |
Quick start
cp .env.example .env # then edit it
make run # http://localhost:8080
make on its own lists every target:
make fix gofmt, templ fmt, go mod tidy
make lint go vet, gofmt check, golangci-lint when installed
make test go test ./...
make build ./foodster
make image build and tag vYYYYMMDD-N (creates a git tag)
make push push the newest tag and :latest
make release image + push
make up/down/logs compose
Configuration
Everything is environment variables. .env is gitignored; start from
.env.example.
| Variable | Default | Purpose |
|---|---|---|
FOODSTER_PASSWORD |
required | Shared password. The app will not start without it. |
FOODSTER_DB |
/data/foodster.db |
SQLite file path. |
TZ |
Europe/Helsinki |
Used for every calendar-day calculation. |
FOODSTER_REPO |
required to build | Image repository, no tag. |
FOODSTER_TAG |
latest |
Tag to run under compose. |
FOODSTER_PORT |
8080 |
Host port to publish. |
Set TZ in development too. Under UTC the date rolls over three hours late,
which is exactly when dinner gets logged.
Deployment
Images are built with Podman and run under Docker Compose on a LAN server. They are OCI images, so either engine works.
make release # build, tag, push
# on the server:
docker compose pull && docker compose up -d
Versions are CalVer — vYYYYMMDD-N, where N is the Nth build that day. The
running version is served at GET /healthz, which is the one route outside
authentication.
There is no database container. SQLite lives on a named volume, so a backup is a file copy.
Security
Access is a single shared password over HTTP Basic — no accounts, no sessions. Credentials are compared in constant time, but Basic auth sends them in cleartext, so this belongs on a private LAN. Put TLS in front of it before exposing it anywhere else.
Mockups
mockups/ holds standalone HTML design studies. Open them directly in a
browser; they are references, not part of the build.
