A small extension to download css and js vendor files from CDNs and host them locally.
Project description
django-download-vendor-files
Setup
Install using pip:
pip install django-vendor-files
Add vendor_files to INSTALLED_APPS in your Django settings:
INSTALLED_APPS = (
...
'vendor_files',
)
Put the vendor directory in STATICFILES_DIRS in your Django settings:
STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'vendor/'),
...
)
Remarks:
- stay first if you wont load vendor libs first
- stay second after you own static if you wish ovveride (patch) vendor lib
Add a VENDOR setting to your Django settings, and add your vendor files with URL and SNI, e.g.:
VENDOR = {
'jquery': {
'url': 'https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0', # Not use '/' at end!
'js': [
{
# finnaly url will be: https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js
'path': 'jquery.min.js',
'sri': 'sha512-894YE6QWD5I59HgZOGReFYm4dnWc1Qt5NtvYSaNcOP+u1T9qYdvdihz0PPSiiqn/+/3e7Jo4EaG7TubfWGUrMQ==',
}
]
},
'bootstrap': {
'url': 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7',
'js': [
{
'path': 'js/bootstrap.min.js',
'sri': 'sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa',
}
],
'css': [
{
'path': 'css/bootstrap.min.css',
'sri': 'sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u',
}
]
}
}
Usage
Put {% load vendor_tags %} at the top of your Django template and the vendor tag , e.g.: {% vendor 'jquery' %}, somewhere in your HTML:
{% load staticfiles %}
{% load vendor_tags %}
<!DOCTYPE html>
<html>
<head>
<title>{{ request.site.name }}</title>
...
{% vendor 'jquery' %}
{% vendor 'bootstrap' %}
</head>
Extended tags, extract only js or css (can be usefull example for django-compressor):
{% vendor 'jquery' 'js' %}
# or you can use
{% vendor_js 'jquery' %}
{% vendor 'jquery' 'css' %}
# or you can use
{% vendor_css 'jquery' %}
Then, you have 2 options:
-
To use a CDN, put
VENDOR_CDN = Truein your Django settings and the vendor tag will be replaced by a<link>or<script>tag using the URLs in the settings. -
To use a local copy, put
VENDOR_CDN = False(or nothing at all) in your Django settings and the vendor tag will be replaced by a<link>or<script>tag using yourSTATIC_PATH. The files can be downloaded:python ./manage.py download_vendor_files
