A high-performance, public media download server built with Rust and Axum. It is designed to serve extremely large files (100GB+) seamlessly and features a retro, Minecraft-themed web dashboard for easy access.

Features

Blazing Fast & Lightweight: Powered by Rust, Axum, and Tokio.
Large File Optimization: Streams files using configurable chunk sizes (default 8MB) to handle massive files with low memory footprint.
Resume Support: Full support for HTTP Range requests, allowing paused or interrupted downloads to be resumed.
Retro Dashboard: A dynamic, Minecraft-style UI built with vanilla HTML/CSS and the VT323 font. Includes 1-click copy-to-clipboard commands for terminal downloading.
No Authentication Required: Built for public, hassle-free access.
Security & Access Control: Built-in security headers and optional IP whitelisting.

Prerequisites

Rust & Cargo (edition 2021)
A .env file for server configuration
A media_config.json file for file registry

Configuration

1. Environment Variables (`.env`)

Create a .env file in the root directory:

PORT=3000
HOST=0.0.0.0
# Request timeout in seconds (default 3600 for 1 hour)
REQUEST_TIMEOUT_SECS=3600
# Streaming chunk size in KB (default 8192 for 8MB)
CHUNK_SIZE_KB=8192
# Optional: comma-separated list of allowed IPs
# ALLOWED_IPS=127.0.0.1,192.168.1.100
# Optional: Domain for generating absolute download URLs
# DOMAIN=https://downloads.example.com

2. Media Registry (`media_config.json`)

Define the files you want to host. Create a media_config.json in the root directory:

{
  "files": {
    "ubuntu-iso": {
      "name": "Ubuntu 24.04 LTS",
      "path": "/path/to/ubuntu-24.04-desktop-amd64.iso",
      "description": "The latest LTS release of Ubuntu.",
      "content_type": "application/x-iso9660-image"
    },
    "large-dataset": {
      "name": "AI Training Dataset",
      "path": "./data/dataset.tar.gz",
      "description": "Huge 150GB dataset for machine learning models."
    }
  }
}

Running the Server

Clone the repository and navigate to the project root.
Build and run the server:
```
cargo run --release
```
Open your browser and navigate to http://localhost:3000 (or your configured HOST and PORT).

Usage

Web Dashboard: Visit the root URL to view available files, their sizes, and descriptions. Click "Download" or copy the provided cURL commands.
Direct Download (Browser): http://localhost:3000/download/{file_id}
cURL Download:
```
curl -O http://localhost:3000/download/{file_id}
```
(For resumable downloads via cURL, add -C -)
