Web Utilities for Go

A collection of utilities for HTTP servers and web applications in Go.

Features

• HTTP Error Handling: Type HTTPError implements both error and http.Handler interfaces
• Resumable Downloads: Auto-resuming HTTP downloads using Range headers
• Data URI Parsing: Parse and work with data: URI schemes
• IP:Port Parsing: Parse and validate IP addresses with ports
• Error-to-Handler Conversion: Convert between errors and HTTP handlers
• PHP Query String Handling: Parse and generate PHP-style query strings with array notation
• HTTP Redirects: Create and handle HTTP redirects as errors

Usage Examples

// Get with auto-resume
resp, err := webutil.Get("https://example.com/large-file.zip")
if err != nil {
    // Handle error
}
defer resp.Close()
// Reading from resp will auto-resume on network errors

// Return HTTP errors from handlers
if !authenticated {
    return webutil.StatusUnauthorized
}

// Parse data URIs
data, mime, err := webutil.ParseDataURI("data:text/plain;base64,SGVsbG8gV29ybGQ=")
