unmaintained

This library has not received regular service in some time. Until it receives regular upkeep, it is strongly recommended to instead:

Use template literals & string interpolation
1. node.js modules + ECMAScript strings provide 90% of the value that template engines once offered, sans a handy CLI for file generation
If you're targeting templates for the browser, consider component-driven HTML generation, e.g. React.renderToString(<MyPage data={...} />). React, Solid, Vue, & other frameworks all have string generation facilities and more powerful options.
For remaining use cases, consider alternative node template engines (handlebars, mustache, etc).

Swig is an awesome, Django/Jinja-like template engine for node.js.

seeking maintainers

Paul Armstrong has stepped down as the primary swig maintainer. Swig is a phenominal project and a template engine that quitely, but strongly, stands tall against the others in a domain full of template engines. If you are interested in being a collaborator, check out the issues page, and let's discuss how to proceed. Don't forget to thank Paul and previous swig collabs for their hard and excellent work!

Documentation

All documentation can be viewed online on the Swig Website.

Basic Example

Template code

<h1>{{ pagename|title }}</h1>
<ul>
{% for author in authors %}
    <li{% if loop.first %} class="first"{% endif %}>{{ author }}</li>
{% endfor %}
</ul>

node.js code

var swig = require("swig-templates");
var template = swig.compileFile("/absolute/path/to/template.html");
var output = template({
  pagename: "awesome people",
  authors: ["Paul", "Jim", "Jane"],
});

Output

<h1>Awesome People</h1>
<ul>
  <li class="first">Paul</li>
  <li>Jim</li>
  <li>Jane</li>
</ul>

For working example see examples/basic

How it works

Swig reads template files and translates them into cached javascript functions. When we later render a template we call the evaluated function, passing a context object as an argument.
