    Swift DSL for type-safe, extensible, and transformable HTML documents

    A Swift DSL for type-safe, extensible, and transformable HTML documents. The popular choice for rendering HTML in Swift these days is to use templating languages, but they expose your application to runtime errors and invalid HTML. Our library prevents these runtime issues at compile-time by embedding HTML directly into Swift’s powerful type system. Underneath the hood these tag functions html, body, h1, etc., are just creating and nesting instances of a Node type, which is a simple Swift...
