Main requirements

Python 3.4+, Django 1.11+.

Installation

To install Django-js-urls, please use pip (or pipenv) as follows:

$ pip install django-js-urls

Once installed you just need to add js_urls to INSTALLED_APPS in your project's settings module:

INSTALLED_APPS = (
    # other apps
    'js_urls',
)

URLs that are included in the Javascript helper tool are configured using a single JS_URL setting. This setting can embed URL namespaces or specific URL names that should be included in the generated Javascript file. For example:

JS_URLS = (
    'admin',
    'blog:article_list',
    'blog:article_detail',
)

Important: only URLs defined in this setting will be included in the generated Javascript file. You don't want to expose all the URLs of your Django project in a Javascript file.

Then you can include the view responsible for generating the Javascript file in your URLs root module:

from js_urls.views import JsUrlsView

urlpatterns = [
    # other urls
    url(r'^js-urls/$', JsUrlsView.as_view(), name='js_urls'),
]

And finally you can include the Javascript script in your base template as follows:

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

Usage

URLs included in the generated Javascript file can be used in your scripts by using the window.reverse function. Here are some example:

const url1 = window.reverse('home');
const url2 = window.reverse('blog:article_list');
const url3 = window.reverse('blog:article_detail', articleId);
const url4 = window.reverse('blog:article_detail', [articleId, ]);
const url5 = window.reverse('blog:article_detail', { pk: articleId });

Settings

JS_URLS

Default: []

The JS_URLS setting allows to define URL namespaces or specific URL names that should be included in the generated Javascript file.

JS_URLS_FUNCTION_NAME

Default: 'reverse'

The JS_URLS_FUNCTION_NAME setting allows customize the name of the function used to reverse URLs on the client side. This function is made available through the window global object.
