Framework for design system development with Nunjucks, Sass, and JavaScript.


Nunjucks is an HTML templating engine for JavaScript based on Jinja. Pangolin.js creates static HTML from Nunjucks files.

Sass + PostCSS

Sass is a CSS preprocessor supporting static variables, nesting, and mixins. PostCSS runs the CSS through plugins, e.g. autoprefixer.


JavaScript files are bundled together with webpack and transpiled with Babel and the env preset to support a specific browser set.

Pangolin.js is currently unmaintained
