Public Archive Downloader SDK

This Go package provides a utility to download and extract tar archives from public URLs. It's tailored for downloading Lux network archives but can be adapted for other use cases.

Features

• Downloads files from predefined URLs.
• Tracks download progress and logs status updates.
• Safely unpacks .tar archives to a target directory.
• Includes security checks to prevent path traversal and manage large files.

func main() { // Initialize the downloader downloader, err := publicarchive.NewDownloader(network.TestnetNetwork(), logging.Debug) if err != nil { fmt.Printf("Failed to create downloader: %v\n", err) os.Exit(1) }

// Start downloading
if err := downloader.Download(); err != nil {
	fmt.Printf("Download failed: %v\n", err)
