Development

Building

go build -o gitcitadel-online cmd/server/main.go

Testing

The server uses a caching system that pre-generates all pages. On first run, pages will be generated and cached. Subsequent requests serve from cache until the refresh interval.

Cache Management

• Pages are cached in memory for fast serving
• Cache rewarming runs in the background at configured intervals
• Media files are cached to disk in cache/media/
• Cache can be cleared by restarting the server

Logging

Logs are structured and can be configured via:

• --log-level flag (debug, info, warn, error)
• --dev flag enables debug logging and verbose output

Content Types Supported

Wiki Articles (Kind 30818)

• AsciiDoc content processing
• Table of contents generation
• Cross-referencing support
• Syntax highlighting

Blog Posts (Kind 30023)

• Markdown/AsciiDoc content
• Image support with caching
• Author profiles
• Timestamps and metadata

E-Books (Kind 30040)

• Publication listings
• Author information
• Sortable table interface
• Links to Alexandria library

Feed Items (Kind 1)

• Real-time note display

Contact Form

The contact form supports two submission methods:

1. Browser Extension: Users can sign with their Nostr browser extension (nos2x, Alby, etc.)
2. Anonymous: Server generates a temporary key pair for anonymous submissions

Both methods publish kind 1 events to configured relays with proper tags for issue tracking.

Security

• Content Security Policy (CSP) headers prevent XSS attacks
• All external scripts are hosted locally
• Input validation on contact form
• Event signature verification for API submissions
• Secure relay connections (WSS)

Performance

• Multi-layer caching (memory + disk)
• Background cache rewarming
• Gzip compression support
• Optimized static asset serving
• Efficient Nostr event parsing
