Safe HTML for Go

Overview

Safe HTML for Gosafehtml is a powerful tool designed to enhance web security by providing immutable string-like types that encapsulate web types such as HTML, JavaScript, and CSS. This approach ensures that the wrapped content is inherently safe against common vulnerabilities like XSS (Cross-Site Scripting). By using these wrappers, developers can confidently work with web content without the constant fear of introducing security flaws.

The addition of subpackages allows for greater flexibility in managing exceptions to safety rules, offering a robust framework for secure web development. Its close resemblance to the familiar html/template interface makes it accessible for developers already accustomed to those tools.

Features

  • Immutable String-Like Types: Wraps web types securely, ensuring that their contents cannot be altered once created, providing a layer of protection against vulnerabilities.

  • XSS Protection: Designed to be safe by construction, these wrappers guard against Cross-Site Scripting and similar web threats.

  • Easy Interpolation: Allows for safe interpolation methods, ensuring that developers can integrate wrapped types without compromising security.

  • Exception Management: Includes additional APIs to control and manage exceptions within safety rules for greater flexibility in development.

  • Template Engine Compatibility: Features a syntax and interface that closely match the existing html/template package, making it simple to adopt.

  • Rich Documentation: Comprehensive API documentation and code examples available through godoc and example_test.go for ease of use.

  • Community Supported: Although not an officially supported Google product, it has a growing community backing and resources for developers.
