Souin is an HTTP caching reverse proxy/middleware compliant with RFC 7234 and related standards. It functions as a pluggable cache layer for various web frameworks (Gin, Echo, Fiber, etc.) and reverse proxies (Caddy, Traefik, Tyk), providing features like request coalescing, surrogate key-based tagging, stale-while-revalidate, and multiple storage backends. The architecture centers on a core middleware handler (`pkg/middleware`) that processes requests through a chain of caching logic, utilizing context propagation for request-scoped values and a pluggable storage system. Key entry points include framework-specific adapter files (e.g., `plugins/gin/souin.go`) and the standalone `main.go` server. Data flows involve intercepting HTTP requests, checking cache storage (in-memory or external like Redis/Badger), serving cached responses or forwarding to upstream, and optionally caching responses based on configuration. External dependencies include Go standard libraries, third-party packages for specific frameworks/storage drivers, and tools like Docker and GoReleaser for deployment.
This repository provides a comprehensive Docker Compose configuration for building a self-hosted NAS (Network Attached Storage) system. It orchestrates over 20 services including media management (Sonarr, Radarr, Lidarr, Bazarr, Prowlarr, qBittorrent, Jellyfin, Jellyseer), a WireGuard VPN (PIA), reverse proxy (Traefik with Let's Encrypt), a homepage dashboard (Homepage), automatic updates (Watchtower), and optional services like AdGuard Home, Home Assistant, Immich, Vaultwarden, Paperless, and more. The architecture is a multi-container Docker stack with a shared network, designed to run on any Docker-capable Linux box. The primary data flow involves downloading media via qBittorrent through a VPN, managing it with *arr applications, and serving it via Jellyfin. The repository includes automation scripts for initial configuration (update-config.sh) and port forwarding updates (pia-shared/portupdate-qbittorrent.sh). It is not a software application with custom code but rather a well-documented, opinionated deployment template. The codebase is primarily configuration files (docker-compose.yml, environment files, nginx configs) with a few bash and JavaScript scripts. The quality is good for its purpose: it is organized, documented, and widely used, but it lacks reusable software components that could be extracted into a new project with minimal modification.
