@rhinostone/swig-django

Django Template Language frontend for the @rhinostone/swig-core template engine. Part of the multi-flavor architecture introduced in 2.0.0 — see ROADMAP.md for the release narrative.

Installation

npm install @rhinostone/swig-django

This pulls in @rhinostone/swig-core as a peer dependency, pinned to the matching version. Frontends and the core release in lockstep — do not mix versions.

Basic example

var swig = require('@rhinostone/swig-django');

var out = swig.render('Hello, {{ name|upper }}!', {
  locals: { name: 'world' }
});
// => Hello, WORLD!

Supported surface (as of 2.7.0)

Renders real Django templates — everything below was cross-checked against Django 5.2.

• Tags — if / elif / else, for / empty (with forloop), block, extends, include, with, autoescape, spaceless, comment, verbatim, cycle, firstof.
• Variable resolution — Django-faithful attribute / dictionary / index lookup. Callable attributes are auto-called (honoring alters_data / do_not_call_in_templates), numeric indexing works ({{ list.0 }}), and dicts iterate via .keys / .values / .items.
• Filter arguments — Django colon syntax ({{ value|date:"Y-m-d" }}).
• Filters — 42 built-ins (add, addslashes, capfirst, center, cut, date, default, default_if_none, divisibleby, escape / e, escapejs, filesizeformat, first, floatformat, force_escape, get_digit, iriencode, join, last, length, linebreaks, linebreaksbr, linenumbers, ljust, lower, make_list, phone2numeric, pluralize, rjust, safe, slice, slugify, striptags, time, title, truncatechars, truncatewords, upper, urlencode, wordcount, wordwrap, yesno). See lib/filters.js for the full list.
• Async — renderFileAsync / compileFileAsync for async loaders, plus renderFile(path, locals, cb) against a loader with async === true.

Explicitly unsupported (parse-time throw or absent)

• No sandboxed-rendering mode — template source is trusted.
• {% load %} and custom tag libraries — no code-loading.
• {% url %}, {% static %}, {% csrf_token %}, {% trans %}, {% blocktrans %} — framework infrastructure, out of scope.
• No whitespace-control ({%- … -%}) — not part of the Django Template Language.
• No is tests — Django's is is identity comparison, not Jinja2-style tests.
• {{ block.super }}, {% for … reversed %}, and one-variable {% for x in dict.items %} are deferred (clear parse-time errors).
• Deferred filters — dictsort / dictsortreversed, stringformat, random, urlize / urlizetrunc, timesince / timeuntil, unordered_list, json_script, truncatechars_html / truncatewords_html, safeseq, pprint.
