# MealQuest

MealQuest is a mobile-first Progressive Web App for weekly dinner planning for
one household. The household lists the dinners it makes regularly, an AI
assistant suggests new dinners to try (swipe "Try it" or "Pass"), and the app
builds a weekly plan, pushes it to Google Calendar, and generates a shopping
list grouped by dinner, kept as a browsable weekly history. It ships as a
single Go service with the React PWA embedded in the binary.

> Status: this repository is the Feature 01 scaffold (Go service with
> `/health`, embedded PWA skeleton, Makefile, Dockerfile, CI). The planned
> application is described in [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md).

## Quick start

Requirements: Go 1.25 and Node.js `^22.22.2 || ^24.15.0 || >=26.0.0` — that
is, 22.22.2 or later on the 22 line, 24.15.0 or later on the 24 line, or 26.0.0
or later. Node.js 23, 24.0–24.14 and 25 are not supported: this is the
`engines` range of jsdom in the committed lockfile, the strictest of all the
web dependencies.

```sh
(cd web && npm ci)
mkdir -p ~/.mealquest-dev   # outside the repository: it holds a secret
chmod 700 ~/.mealquest-dev
head -c 32 /dev/urandom | base64 > ~/.mealquest-dev/secret_key
chmod 600 ~/.mealquest-dev/secret_key
export MEALQUEST_HTTP_ADDR=:8080
export MEALQUEST_PUBLIC_URL=http://localhost:5173
export MEALQUEST_DATA_DIR="$HOME/.mealquest-dev"
export MEALQUEST_SHUTDOWN_TIMEOUT=10s
export MEALQUEST_SECRET_KEY_FILE="$HOME/.mealquest-dev/secret_key"
# Authentik OAuth2/OpenID provider for MealQuest (redirect URI:
# $MEALQUEST_PUBLIC_URL/auth/callback). Save its client secret to the file.
export MEALQUEST_OIDC_ISSUER=https://auth.example.com/application/o/mealquest/
export MEALQUEST_OIDC_CLIENT_ID=mealquest
export MEALQUEST_OIDC_CLIENT_SECRET_FILE="$HOME/.mealquest-dev/oidc_client_secret"
export MEALQUEST_OIDC_ALLOWED_GROUPS=mealquest-admin
# Optional: sessions end after MEALQUEST_SESSION_IDLE unused (default 720h)
# and always MEALQUEST_SESSION_MAX after sign-in (default 4320h).
# export MEALQUEST_SESSION_IDLE=720h
# export MEALQUEST_SESSION_MAX=4320h
# Optional: comma-separated IPs/CIDRs of reverse proxies whose
# X-Forwarded-For/-Proto headers are honoured (production: Traefik). Unset
# trusts no peer, which is right for local development.
# export MEALQUEST_TRUSTED_PROXY=10.60.1.33
# Optional: a SearXNG instance the Settings screen suggests as the recipe
# search URL until one is saved.
# export MEALQUEST_SEARXNG_URL=http://localhost:8888
export MEALQUEST_DEFAULT_TZ=America/New_York
make dev
```

`make dev` runs the Go server on `:8080` and the Vite dev server on `:5173`
(which proxies `/api`, `/auth` and `/media` to `:8080`). Open
http://localhost:5173. Configuration is environment-only and fails fast:
every variable above is required except the commented-out session
lifetimes (when set they must be positive, with MAX at least IDLE),
trusted proxy list (every entry must be an IP or CIDR), the SearXNG URL
(an absolute `http://` or `https://` URL without credentials, a query or a
fragment) and `MEALQUEST_DEFAULT_TZ`, and
secrets are read only from files named by `*_FILE` variables. `MEALQUEST_PUBLIC_URL`, `MEALQUEST_OIDC_ISSUER` and the
endpoints the issuer advertises must be `https://`; plain `http://` is
accepted only for `localhost`, `127.0.0.1` and `[::1]`.
`MEALQUEST_DEFAULT_TZ` is the IANA zone the household settings are created
with on first boot: until those settings exist, boot fails unless it is a
valid IANA zone. Later boots ignore it, set or not (change the zone in
household settings instead).
