Nunjucks is a full-featured JavaScript templating engine heavily inspired by Jinja2, supporting template inheritance, macros, autoescaping, asynchronous control, and custom filters/extensions. It runs in Node.js and all modern browsers, with precompilation for a small runtime footprint.

Use cases

  • render html templates in a node.js server
  • jinja2-style templating for javascript
  • share templates between server and browser
  • precompile templates for fast client-side rendering
  • build static site pages with template inheritance
  • port django/jinja2 templates to a javascript stack

When to choose

  • you want jinja2-like syntax in JavaScript
  • you need template inheritance, macros, and filters
  • you need the same templates in Node and the browser
  • you're using frameworks like Eleventy or Apostrophe CMS that rely on it

When to avoid

  • you prefer logic-less templates like Handlebars or Mustache
  • you're in a React/Vue-style component ecosystem
  • you need streaming or very modern async template features
