# Yuvomi - Environment Variables
# Copy this file to .env and adjust the values.

# Server
PORT=3000
NODE_ENV=production
# LOG_LEVEL=info   # debug, info, warn, error (default: info)

# Container host port mapping (compose maps OIKOS_HTTP_PORT:3000).
# The app inside the container always listens on 3000; change only the host port here.
OIKOS_HTTP_PORT=3000
# Host bind address for the published port (podman-compose.yml only; default 0.0.0.0).
# Set to 127.0.0.1 for rootless Podman behind a reverse proxy on the same host.
# OIKOS_HTTP_BIND=0.0.0.0
# TZ=Europe/Berlin   # Container timezone (default: UTC). Also the fallback zone for
#                    # events pushed to Google Calendar when the target calendar
#                    # reports no time zone of its own.

# Container storage paths (bind mounts)
# DATA_DIR=./data              # Host folder for the database and stored app data
# BACKUP_DIR=./backups         # Host folder for scheduled backups
# These two are HOST paths, used only by docker-compose.yml / podman-compose.yml to
# build the volume mapping. Inside the container the app always writes to /data and
# /backups (the compose files set DB_PATH and BACKUP_DIR accordingly). Do not pass
# this file to a bare `docker run --env-file`: BACKUP_DIR=./backups would then point
# the app at /app/backups, which is outside the mounted volume and not writable.
# On SELinux systems (RHEL/Fedora/CentOS Stream) use podman-compose.yml — it adds
# the :Z relabel automatically so the container can access these folders.

# Session
SESSION_SECRET=REPLACE_WITH_A_LONG_RANDOM_STRING
# SESSION_SECURE=true    # Set when running behind an HTTPS reverse proxy (Caddy, Nginx, Traefik)

# Database (SQLite/SQLCipher)
# Legacy installs may still have /data/oikos.db — the app auto-migrates it to yuvomi.db on boot.
DB_PATH=/data/yuvomi.db
DB_ENCRYPTION_KEY=REPLACE_WITH_A_STRONG_ENCRYPTION_KEY

# NOTE: The optional integrations below (weather, Google/OIDC, WebDAV backup) may
# transmit data to third parties, some outside the EU/EEA. If you run Yuvomi under
# the GDPR, see docs/PRIVACY-FOR-SELFHOSTERS.md for per-service third-country
# assessments, data-processing-agreement notes and log-retention guidance.

# Weather widget — Open-Meteo (recommended, free, no API key). Set your coordinates:

# Google Calendar (optional)
GOOGLE_CLIENT_ID=
GOOGLE_CLIENT_SECRET=
GOOGLE_REDIRECT_URI=https://your-domain.com/api/v1/calendar/google/callback

# Google Drive document storage (optional)
# Enable the Google Drive API in the same Cloud project. Yuvomi requests only
# https://www.googleapis.com/auth/drive.file and accesses files it creates.
# Leave both Drive-specific credentials empty to reuse GOOGLE_CLIENT_ID and
# GOOGLE_CLIENT_SECRET. The Drive redirect URI is always separate and exact.

GOOGLE_DRIVE_REDIRECT_URI=https://your-domain.com/api/v1/documents/storage/google-drive/callback
# After deployment, connect Drive and explicitly select it under
# Settings -> Documents -> Storage. Connecting alone never activates uploads.

# Opt-in: Bestehende Accounts per E-Mail verknüpfen, wenn der IdP keinen

# Authentik-Versionen ohne explizites email_verified-Mapping).
# OIDC_TRUST_EMAIL_WITHOUT_VERIFIED_CLAIM=true

# Apple Calendar CalDAV (optional)

# Sync interval in minutes for calendars and contacts (default: 15)
SYNC_INTERVAL_MINUTES=15

# ICS calendar subscriptions: allow http:// and private/local network feeds
# (e.g. Sonarr/Radarr/Home Assistant in the same LAN). Set true to lift the
# SSRF protection for ICS subscriptions — only in controlled environments.

# Automatic Backups
# BACKUP_ENABLED=true                  # Enable/disable automated backups (default: true)

# TZ=Europe/Berlin                     # Timezone for scheduled backups (default: UTC, see above)

# WebDAV Backup Target (optional — uploads each backup to a WebDAV server)
# Supported: Nextcloud, ownCloud, Hetzner Storage Box, Infomaniak kDrive, etc.
# If set here, these values take precedence over the UI configuration in Settings → Backup.
# WEBDAV_BACKUP_ENABLED=true

# WEBDAV_BACKUP_KEEP=10                # Remote backups to keep (default: 7)

# Local Folder Document Storage (optional — stores newly uploaded document files on a mounted host folder)
# When enabled, uploads are written to DOCUMENT_STORAGE_LOCAL_PATH/<key> instead of the database BLOB,
# and this backend takes precedence over WebDAV. Mount the folder into the container (see docker-compose.yml).
# Existing database/WebDAV documents remain readable; no automatic migration is performed.
# DOCUMENT_STORAGE_LOCAL_ENABLED=false
# DOCUMENT_STORAGE_LOCAL_PATH=/documents

# WebDAV Document Storage (optional — stores newly uploaded document files remotely)
# Non-empty values override the corresponding database settings. Existing WebDAV
# documents remain readable when new WebDAV uploads are disabled. Use this trusted
# deployment configuration for private/LAN WebDAV targets; UI-managed URLs must be public.
# DOCUMENT_STORAGE_WEBDAV_ENABLED=false

# DOCUMENT_STORAGE_WEBDAV_ALLOW_PRIVATE_NETWORK=false  # Set true to allow local/private network WebDAV targets (e.g. Nextcloud in same Docker network)

# Web Push (PWA notifications, optional)
# Delivers due reminders as system notifications even when the app is closed (requires HTTPS).
# VAPID keys are generated automatically on first use and stored in the database — leave these
# unset for a zero-config setup. Set them only to pin a fixed key pair across redeployments
# (generate with: npx web-push generate-vapid-keys).
# VAPID_PUBLIC_KEY=
# VAPID_PRIVATE_KEY=
# VAPID_SUBJECT=mailto:admin@example.com   # Contact URI sent to push services (default: mailto:admin@localhost)

# Email / SMTP (optional)
# Configure an SMTP server to enable the "Forgot password" self-service flow.
# Can also be set in Settings → Administration → Email; non-empty values here override the DB.
# EMAIL_SMTP_HOST=smtp.example.com
# EMAIL_SMTP_PORT=587

# Absolute origin for password-reset links and calendar export-feed URLs. REQUIRED for

# MCP endpoint (/mcp): the built-in Model Context Protocol bridge (call_api_operation)

# Reverse proxy trust (controls which X-Forwarded-For / X-Real-IP values Express accepts)
# Default: 1 (trust one hop — correct for Caddy, nginx, Traefik in Docker)
# Set to a subnet when behind multiple proxy layers, e.g.:
#   TRUST_PROXY=172.16.0.0/12,10.0.0.0/8
# Set to "loopback" for direct (no proxy) deployments.
