Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Javascript url handling for Django that doesn’t hurt.

Overview

Django JS Reverse is a small django app that makes url handling of named urls <https://docs.djangoproject.com/en/dev/topics/http/urls/#naming-url-patterns>__ in javascript easy and non-annoying..

For example you can retrieve a named url:

urls.py:

::

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

in javascript like:

::

Urls.betterliving_get_house('house', 12)

Result:

::

/betterliving/house/12/

Installation

Install using pip

::

pip install django-js-reverse

… or clone the project from github.

::

git clone https://github.com/ierror/django-js-reverse.git

Add 'django_js_reverse' to your INSTALLED_APPS setting.

::

INSTALLED_APPS = (
    ...
    'django_js_reverse',
)

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

::

./manage.py 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 <https://django-csp.readthedocs.io/>__

::

{% load js_reverse %}

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

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.betterliving_get_house('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 })

Options

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

::

JS_REVERSE_JS_VAR_NAME = 'Urls'

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

::

JS_REVERSE_JS_GLOBAL_OBJECT_NAME = 'window'

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

::

JS_REVERSE_JS_MINIFY = False

By default all namespaces are included

::

JS_REVERSE_EXCLUDE_NAMESPACES = []

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 "foo\0" 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:

::

JS_REVERSE_SCRIPT_PREFIX = '/myprefix/'

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

::

JS_REVERSE_OUTPUT_PATH = 'some_path'

Running the test suite

::

tox
