Swig is an archived JavaScript template engine inspired by Django and Jinja syntax. It renders templates in Node.js and major web browsers and can integrate with Express applications. Developers can use inheritance, includes, variables, filters, loops, conditionals, and other familiar template constructs. Automatic output escaping helps produce safer HTML by default. The engine can be extended with custom filters, tags, and related extras to support application-specific behavior. It was designed to remain compact while offering a full set of server-side rendering conveniences. The repository was archived in 2018 and is no longer maintained, so it is best suited to legacy applications, migration work, or historical study.
