# PicPeak Environment Configuration
# Copy this file to .env and update with your values

# Environment
NODE_ENV=production

# JWT Secret (generate with: openssl rand -base64 64)
JWT_SECRET=your_very_long_random_jwt_secret_here

# Auth cookie Secure flag
#   unset  - default: follows NODE_ENV (production=true, dev=false)
#   true   - always set Secure (HTTPS-only cookies; breaks plain-HTTP access)
#   false  - never set Secure (allows HTTP; cookies not protected on HTTPS)
#   auto   - decide per request: Secure on HTTPS, not on HTTP
#
# Use COOKIE_SECURE=auto if your deployment is reachable over both HTTPS
# (via reverse proxy like Nginx Proxy Manager, Traefik, Caddy) AND plain
# HTTP (e.g. LAN access at http://192.168.x.x:3010). The backend reads
# req.secure from Express, which respects the X-Forwarded-Proto header
# when the proxy is in the trust list.
#
# Requirements for auto mode:
#   1. Your reverse proxy MUST send X-Forwarded-Proto: https on HTTPS
#      requests. Standard configs for NPM/Traefik/Caddy do this by default.
#   2. The proxy must be on a trusted IP range. By default PicPeak trusts
#      loopback and private networks (127.0.0.1, 10.x, 172.16-31.x,
#      192.168.x, link-local). Proxies outside those ranges need custom
#      trust proxy configuration.
# COOKIE_SECURE=auto

# Cookie SameSite attribute (Lax | Strict | None). Default: Lax
# COOKIE_SAMESITE=Lax

# Cookie Domain — set this if serving auth cookies across subdomains.
# Leave unset for same-origin setups.

# Database Configuration (PostgreSQL)

# Static HTML title + description used for social link previews when the

# For pre-built images and production behind a reverse proxy, keep '/api'.

# ─── Storage Backend ────────────────────────────────────────────────────────
# PicPeak can store photos, thumbnails and archive zips on the local filesystem
# (default) or on any S3-compatible object store (AWS S3, MinIO, Cloudflare R2,
# Backblaze B2, Wasabi, DigitalOcean Spaces, …).
#
# STORAGE_BACKEND=local (default)
#   Uses STORAGE_PATH on the local filesystem. Backwards compatible — every
#   existing deployment keeps working unchanged.
#
# STORAGE_BACKEND=s3
#   Reads STORAGE_S3_* below. Auto-import via the filesystem watcher is
#   disabled in this mode (S3 has no inotify) — every photo must enter via the
#   admin upload UI/API. Run `node backend/scripts/migrate-storage.js` to copy
#   existing local content to S3 before flipping the env.
#
# STORAGE_BACKEND=local
#
# STORAGE_S3_BUCKET=picpeak
# STORAGE_S3_REGION=us-east-1
# STORAGE_S3_ACCESS_KEY=AKIAxxxxxxxxxxxxxxxx
# STORAGE_S3_SECRET_KEY=xxxxxxxxxxxxxxxxxxxxxxxx
# Custom endpoint — set this for MinIO / R2 / B2 / Spaces. Leave unset for AWS.
# STORAGE_S3_ENDPOINT=https://s3.us-west-002.backblazeb2.com
# Optional namespace prefix inside the bucket — useful for multi-deployment buckets.
# STORAGE_S3_PREFIX=picpeak
# STORAGE_S3_FORCE_PATH_STYLE=false   # MinIO needs true; auto-on when endpoint is set
# STORAGE_S3_SSL=true
#
# Minimum IAM policy (AWS S3) for the bucket above:
#   {
#     "Version": "2012-10-17",
#     "Statement": [{
#       "Effect": "Allow",
#       "Action": [
#         "s3:GetObject", "s3:PutObject", "s3:DeleteObject",
#         "s3:ListBucket", "s3:GetBucketLocation"
#       ],
#       "Resource": [
#         "arn:aws:s3:::picpeak",
#         "arn:aws:s3:::picpeak/*"
#       ]
#     }]
#   }
#
# EXTERNAL_MEDIA_ROOT (above) always lives on the local filesystem regardless
# of STORAGE_BACKEND — reference-mode galleries are not migrated to S3 in v1.

# ─── Outbound Webhooks (#327) ────────────────────────────────────────────────
# PicPeak POSTs event/photo lifecycle notifications to URLs you configure
# under Settings → Webhooks. Each delivery is signed HMAC-SHA256 with a
# per-webhook secret in the X-PicPeak-Signature header.
#
# WEBHOOK_ALLOW_PRIVATE_URLS (default: false)
#   Block URLs resolving to private IPs / loopback / .local etc. as an
#   SSRF mitigation. Set to "true" ONLY in dev when your receiver is on
#   the same docker network or localhost. Production deployments must
#   leave this OFF.
# WEBHOOK_ALLOW_PRIVATE_URLS=false
#
# WEBHOOK_DELIVERY_INTERVAL_MS (default: 5000)
#   How often the worker polls webhook_deliveries for pending rows.
# WEBHOOK_DELIVERY_INTERVAL_MS=5000
#
# WEBHOOK_DELIVERY_CONCURRENCY (default: 5)
#   Maximum in-flight deliveries per worker tick. One slow consumer can
#   monopolize all 5 slots — bump this if your receivers are slow OR ship
#   a separate webhook-only deployment.
# WEBHOOK_DELIVERY_CONCURRENCY=5
#
# WEBHOOK_HTTP_TIMEOUT_MS (default: 10000)
#   Per-request timeout. Beyond this, the delivery is recorded as a
#   network error and retried.
# WEBHOOK_HTTP_TIMEOUT_MS=10000
#
# WEBHOOK_MAX_ATTEMPTS (default: 5)
#   Total attempts before a delivery is marked failed. Backoff between
#   attempts is exponential: 1m, 5m, 30m, 2h, 12h.
# WEBHOOK_MAX_ATTEMPTS=5

# Note on FRONTEND_API_URL (documentation only):
# When using pre-built frontend images, runtime env vars cannot override the built JS.
# Do NOT rely on FRONTEND_API_URL in Compose. Instead, keep VITE_API_URL=/api and
# let the frontend Nginx proxy /api to the backend. Only if you rebuild the frontend
# should you change VITE_API_URL at build time.
