# Copy to .env for `docker compose up --build`. Local-dev runs (cargo run

# Production note: COOKIE_SECURE=true (the default below) makes browsers
# refuse to send the session cookie over plain HTTP. Run with a TLS-
# terminating reverse proxy (Caddy, Traefik, nginx) in front — the
# compose file here doesn't ship one. Local/dev runs without HTTPS
# should set COOKIE_SECURE=false.

# ----- Postgres -----
# These are read by the Postgres container *and* by DATABASE_URL below;
# changing them after the first boot won't migrate existing data, so set
# them up front for any new deployment.
#
# POSTGRES_PASSWORD is REQUIRED — docker-compose.yml fails fast if it
# isn't set in this file, to prevent a deploy without an .env booting
# Postgres with a publicly-known credential.

# ----- Auth / cookies -----
# COOKIE_SECURE controls whether the `Secure` flag is set on the session
# cookie. Keep `true` in production (HTTPS); set to `false` if you're
# serving over plain HTTP locally (e.g., behind a dev reverse proxy).
COOKIE_SECURE=true
# COOKIE_DOMAIN scopes the session cookie. Leave empty to default to the
# requesting host. Set when serving the API and frontend on subdomains of
# a shared parent (e.g., `.example.com`) so the cookie is shared.
COOKIE_DOMAIN=
# Session lifetime in days. Expired sessions are no longer accepted and
# get reaped lazily.
SESSION_TTL_DAYS=30

# ----- Auth brute-force rate limits -----
# Token-bucket budget shared across /auth/login, /auth/register, and
# /auth/me/password. Set per_sec=0 to disable (e.g. behind a
# rate-limiting reverse proxy that already enforces a budget).
AUTH_RATE_PER_SEC=5
AUTH_RATE_BURST=10

# ----- CORS -----
# Comma-separated origins allowed to call the API with credentials.
# Default is empty: same-origin only. Set when frontend and backend live
# on different hosts. Example: https://app.example.com,https://app.example.de
CORS_ALLOWED_ORIGINS=

# ----- Upload limits -----
# Per-request body cap. axum rejects oversized requests with 413 before
# our handlers run. Default 200 MiB.
MAX_REQUEST_BYTES=209715200
# Per-image-part cap. Enforced after reading each part, so a single
# oversized image is rejected even when the total request fits.
# Default 20 MiB.
MAX_FILE_BYTES=20971520

# ----- Crawler download safety -----
# Hosts the crawler is allowed to fetch images/covers from, in addition
# to CRAWLER_START_URL's host and CRAWLER_CDN_HOST. Comma-separated.
# Defends against SSRF via scraped <img src="http://10.0.0.1/...">.
CRAWLER_DOWNLOAD_ALLOWLIST=
# Bypass the host allowlist entirely. Intended for sources that shard
# images across numbered CDN subdomains (cdn1/cdn2/…) where enumerating
# every host upfront is impractical. The private-IP / localhost / non-
# http(s) scheme defenses STAY ON — a scraped <img src="http://10.0.0.1/">
# is still refused with this flag set.
CRAWLER_ALLOW_ANY_HOST=false
# Hard cap on a single image body. Default 32 MiB.
CRAWLER_MAX_IMAGE_BYTES=33554432

# ----- Frontend -----
# The frontend container runs SvelteKit's Node adapter on :3000 and
# proxies /api/* to BACKEND_URL via src/hooks.server.ts. In compose the
# default `http://backend:8080` reaches the backend service over the
# internal docker network. Override only if you're running the
# frontend container against a backend somewhere else.
BACKEND_URL=http://backend:8080
# Per-request wall-clock cap for the /api/* reverse proxy (milliseconds).
# Default 300000 (5 min) covers a typical 200 MiB chapter upload over
# 25 Mbps; raise for users on slower upstream links or lower if a
# tighter front proxy already bounds the request lifetime.
BACKEND_PROXY_TIMEOUT_MS=300000
