Harden gallery authentication and authorization, consolidate gallery workflows, and prevent token-bearing URLs from leaking through nginx request error logs.
When PicPeak runs behind NPM / Traefik / Caddy, the inner nginx receives
plain HTTP from the outer proxy. The previous `X-Forwarded-Proto $scheme`
therefore always forwarded "http" to the backend, even when the public URL
was HTTPS. Express has `trust proxy` enabled for loopback/linklocal, so
req.secure became false, the Secure cookie flag wasn't set, and generated
URLs (cookies, tokens) used http://.
Add a top-of-file `map` block that picks the incoming X-Forwarded-Proto
when present and falls back to `$scheme` for direct access. Applied to both
nginx.conf (bundled production image) and nginx.dev.conf.
Validated with `nginx -t` against nginx:1.28-alpine (the same image used
by Dockerfile.prod / Dockerfile).
WhatsApp / Slack / Facebook / Twitter previews showed nothing useful for
shared gallery links — the SPA's stub index.html has no OG tags and the
meta-injection in DynamicFavicon happens at runtime, which crawlers
never see (they don't execute JS).
Add a backend OG handler at /og/gallery/:slug that returns minimal HTML
with proper og:* and twitter:* meta sourced from the event row + branding
settings (event name, formatted date, welcome_message excerpt as
description, configured logo as the preview image, FRONTEND_URL-based
canonical). Honours slug redirects so renamed galleries still get rich
previews.
Wire crawler detection in both nginx configs (production and dev) — UA
match against the standard list (facebookexternalhit, WhatsApp, Slackbot,
Twitterbot, Discordbot, LinkedInBot, etc.) triggers an internal
rewrite to /og/gallery/:slug, while humans fall through to the SPA via
try_files. The OG endpoint is also wired into the native-install SPA
fallback in server.js for setups that bypass nginx.
The OG image is intentionally the brand logo, not a gallery photo —
crawlers fetch it without auth, and password-protected gallery photos
must not leak via share previews.
Original: feat: enhance security logging and ensure rate limit blocks are properly tracked
- Add comprehensive logging for rate limit blocks with full request details
- IP address (with proper proxy detection), user agent, headers, timestamps
- Rate limit info (current count, limit, remaining, reset time)
- Separate tracking for auth vs general endpoints
- Enhance authentication failure logging
- JWT validation failures with detailed error info
- Admin auth attempts without token
- Failed token validation with user context
- All events include IP, path, method, user agent
- Improve Winston logger configuration for production
- Add automatic log rotation (10MB errors, 50MB combined)
- Create separate security.log for auth/rate limit events
- Ensure logs directory exists automatically
- Add structured JSON format for log aggregation
- Support container logging with LOG_TO_CONSOLE env var
- Create comprehensive documentation
- Security logging guide with examples
- Monitoring recommendations
- Configuration reference
- Add test script to verify logging functionality
All rate limit settings remain configurable via admin panel:
- Window duration, max requests, auth limits
- Skip authenticated requests option
- Public endpoints only option
