safehtml provides immutable string-like types that wrap web types such as HTML, JavaScript and CSS. These wrappers are safe by construction against XSS and similar web vulnerabilities, and they can only be interpolated in safe ways. You can read more about our approach to web security in our whitepaper, or this OWASP talk.

Additional subpackages provide APIs for managing exceptions to the safety rules, and a template engine with a syntax and interface that closely matches html/template. You can refer to the godoc for each (sub)package for the API documentation and code examples. More end-to-end demos are available in example_test.go.
