Javascript url handling for Django that doesn't hurt.

Project description

Javascript url handling for Django that doesn’t hurt.

This package is now maintained by Vinta Software but it was originally created by @ierror. Many thanks to you, Bernhard.


Django JS Reverse is a small django app that makes url handling of named urls in javascript easy and non-annoying..

For example you can retrieve a named url:

url(r'^/betterliving/(?P<category_slug>[-\w]+)/(?P<entry_pk>\d+)/$', 'get_house', name='betterliving_get_house'),

in javascript like:

Urls.betterlivingGetHouse('house', 12)




Python version

Django versions


4.2, 4.1, 4.0, 3.2


4.2, 4.1, 4.0, 3.2


4.2, 4.1, 4.0, 3.2


4.2, 4.1, 4.0, 3.2


Install using pip

pip install django-js-reverse

… or clone the project from github.

git clone

Add 'django_js_reverse' to your INSTALLED_APPS setting.


Usage with webpack

Install using npm

npm install --save django-js-reverse

Include none-cached view …

urlpatterns = patterns('',
    url(r'^jsreverse.json$', 'django_js_reverse.views.urls_json', name='js_reverse'),

… or a cached one that delivers the urls JSON

from django_js_reverse import views
urlpatterns = patterns('',
    url(r'^jsreverse.json$', cache_page(3600)(views.urls_json), name='js_reverse'),

Include JavaScript in your bundle:

// utils/djangoReverse.mjs
import _ from 'lodash/fp';
import djangoJsReverse from 'django-js-reverse';

export default _.once(
  async () => {
    const res = await fetch('/jsreverse.json');
    const data = await res.json();
    return djangoJsReverse(data);
// somePlace.mjs
import djangoReverse from './utils/djangoReverse';

(async () => {
  const urls = await djangoReverse();
  const url = urls.someViewName('some-arg');

Usage as static file

First generate static file by

./ collectstatic_js_reverse

If you change some urls or add an app and want to update the reverse.js file, run the command again.

After this add the file to your template

<script src="{% static 'django_js_reverse/js/reverse.js' %}"></script>

Usage with views

Include none-cached view …

urlpatterns = patterns('',
    url(r'^jsreverse/$', 'django_js_reverse.views.urls_js', name='js_reverse'),

… or a cached one that delivers the urls javascript

from django_js_reverse.views import urls_js
urlpatterns = patterns('',
    url(r'^jsreverse/$', cache_page(3600)(urls_js), name='js_reverse'),

Include javascript in your template

<script src="{% url js_reverse %}" type="text/javascript"></script>

or, if you are using Django > 1.5

<script src="{% url 'js_reverse' %}" type="text/javascript"></script>

Usage as template tag

You can place the js_reverse JavaScript inline into your templates, however use of inline JavaScript is not recommended, because it will make it impossible to deploy a secure Content Security Policy. See django-csp

{% load js_reverse %}

<script type="text/javascript" charset="utf-8">
    {% js_reverse_inline %}

Use the urls in javascript

If your url names are valid javascript identifiers ([$A-Z_][-Z_$]*)i you can access them by the Dot notation:

Urls.betterlivingGetHouse('house', 12)

If the named url contains invalid identifiers use the Square bracket notation instead:

Urls['betterliving-get-house']('house', 12)
Urls['namespace:betterliving-get-house']('house', 12)

You can also pass javascript objects to match keyword aguments like the examples bellow:

Urls['betterliving-get-house']({ category_slug: 'house', entry_pk: 12 })
Urls['namespace:betterliving-get-house']({ category_slug: 'house', entry_pk: 12 })


Optionally, you can overwrite the default javascript variable ‘Urls’ used to access the named urls by django setting


Optionally, you can change the name of the global object the javascript variable used to access the named urls is attached to. Default is this


Optionally, you can disable the minfication of the generated javascript file by django setting


By default all namespaces are included


To exclude any namespaces from the generated javascript file, add them to the JS_REVERSE_EXCLUDE_NAMESPACES setting

JS_REVERSE_EXCLUDE_NAMESPACES = ['admin', 'djdt', ...]

If you want to include only specific namespaces add them to the JS_REVERSE_INCLUDE_ONLY_NAMESPACES setting tips: * Use “” (empty string) for urls without namespace * Use “foo0” to include urls just from “foo” namaspace and not from any subnamespaces (e.g. “foo:bar”)

JS_REVERSE_INCLUDE_ONLY_NAMESPACES = ['poll', 'calendar', ...]

If you run your application under a subpath, the collectstatic_js_reverse needs to take care of this. Define the prefix in your django settings:


By default collectstatic_js_reverse writes its output (reverse.js) to your project’s STATIC_ROOT. You can change the output path:
