Nunjucks is a full featured templating engine for javascript. It is heavily inspired by jinja2. View the docs here.
The main repository for nunjucks can be found at https://github.com/mozilla/nunjucks. This is an experimental rewrite that is not yet production ready.
The code in this repository adheres very closely to the functionality of Jinja; much more so than earlier versions of nunjucks.
See the release tracking ticket for a list of features that are known to be incomplete. If you should come across a feature not listed, or a bug regression, please open a new issue.
