README

A Laravel-based backend service for managing downloads in Clarion. This package provides comprehensive torrent management capabilities with support for multiple torrent client implementations.

Overview

The Download Manager Backend is a Clarion app component that enables users to:

• Manage torrent downloads across multiple servers
• Track download status and completion
• Support multiple torrent client types (currently Transmission)

Features

• Multi-Server Support: Manage torrents across multiple torrent servers and client types
• Torrent Lifecycle Management: Add, monitor, and remove torrents with automatic status tracking
• RESTful API: Complete CRUD operations for torrents and torrent servers
• Extensible Client Architecture: Plugin-based system for supporting different torrent clients
• User Association: Link torrents to specific users with authentication support
• Automatic Processing: Background commands for checking torrent status

Architecture

Models

Torrent

Represents individual torrent downloads with the following attributes:

• local_node: Node identifier for distributed tracking
• server_id: Reference to the torrent server handling the download
• user_id: Associated user (when authenticated)
• magnetURI: Magnet link for the torrent
• hash_string: Unique torrent hash identifier
• name: Display name (auto-extracted from magnet URI)
• completed_at: Timestamp when download completed

TorrentServer

Represents torrent client servers with:

• local_node: Node identifier
• address: Server connection address
• type: Client type (e.g., "Transmission")

Controllers

TorrentController

• index(): List all torrents
• store(): Add new torrent from magnet URI
• show(): Get specific torrent details
• update(): Modify torrent properties
• markIncomplete(): Reset completion status
• destroy(): Remove torrent

TorrentServerController

• Standard CRUD operations for torrent servers
• getClientTypes(): List supported client types

Torrent Clients

TransmissionClient

Implementation for Transmission torrent client with:

• RPC communication via HTTP
• Session management with X-Transmission-Session-Id headers
• Methods for adding, checking status, and removing torrents

TorrentClientBase

Abstract base class for implementing additional torrent clients

Commands

CheckTorrent (torrent:check)

Background command that:

• Scans for incomplete torrents
• Checks status with respective torrent clients
• Updates completion timestamps
• Processes torrent lifecycle events

API Endpoints

All endpoints require authentication (auth:api middleware) and use the configured route prefix.

Torrent Servers

• GET /torrent-servers/client-types - Get supported client types
• GET /torrent-servers - List all servers
• POST /torrent-servers - Create new server
• GET /torrent-servers/{id} - Get server details
• PUT /torrent-servers/{id} - Update server
• DELETE /torrent-servers/{id} - Remove server

Torrents

• GET /torrents - List all torrents
• POST /torrents - Add new torrent
• GET /torrents/{id} - Get torrent details
• PUT /torrents/{id} - Update torrent
• DELETE /torrents/{id} - Remove torrent
• PATCH /torrents/{id}/mark-incomplete - Mark as incomplete

Database Schema

Torrents Table

- id (UUID, primary key)
- local_node (string)
- server_id (UUID, foreign key)
- user_id (UUID, nullable)
- magnetURI (text)
- hash_string (string, nullable)
- name (string, nullable)
- completed_at (timestamp, nullable)
- created_at/updated_at (timestamps)
- deleted_at (soft deletes)

Torrent Servers Table

- id (UUID, primary key)
- local_node (string)
- address (string)
- type (string)
- created_at/updated_at (timestamps)
- deleted_at (soft deletes)

Usage Examples

Adding a Torrent

POST /api/torrents
{
    "magnetURI": "magnet:?xt=urn:btih:...",
    "server_id": "uuid-of-server" // optional, uses default if not specified
}

Checking Torrent Status

The system automatically processes torrents via the torrent:check command, which can be run manually or scheduled:

php artisan torrent:check

Adding a New Torrent Server

POST /api/torrent-servers
{
    "address": "192.168.1.100:9091",
    "type": "Transmission"
}

Extending Client Support

To add support for new torrent clients:

1. Create a new class extending TorrentClientBase
2. Implement required methods: add(), check(), remove()
3. Set the static $type property
4. Place in src/TorrentClients/ directory

Example:

class QBittorrentClient extends TorrentClientBase
{
    public static $type = "qBittorrent";
    
    public function add($torrent) { /* implementation */ }
    public function check($hashString) { /* implementation */ }
    public function remove($hashString) { /* implementation */ }
}
