HopCDN Client for Django

django-hopcdn is a lightweight Django library that simplifies loading CSS frameworks from your own CDN. It reads a manifest file served by the CDN to resolve the correct hashed filenames and generates <link> tags using a simple template tag.

✅ Features

📦 Loads hashed/minified CSS from your CDN using a manifest
🚀 Simple {% hopcdn_stylesheet 'name' %} tag for easy integration
⚡ In-memory caching for performance (thread-safe)
🛠️ Fallback-safe if manifest is missing or incomplete
🧱 Easy to extend or override

🛠️ Installation

pip install django-hopcdn

Add to INSTALLED_APPS:

INSTALLED_APPS = [
    ...,
    'django_hopcdn',
]

🚀 Quick Start

1. Configure settings

Add the CDN base URL in your settings.py:

CDN_URL = "https://cdn.hopsenn.com/"

Your CDN must expose a manifest.json at:

https://cdn.hopsenn.com/manifest.json

Example manifest.json:

{
  "main": "main.ab12cd.css",
  "theme": "theme.f8d33e.css"
}

2. Use the template tag

In your template:

{% load hopcdn_tags %}
{% hopcdn_stylesheet 'main' %}
{% hopcdn_stylesheet 'theme' %}

This will render:

<link rel="stylesheet" href="https://cdn.hopsenn.com/styles/main/main.ab12cd.css">
<link rel="stylesheet" href="https://cdn.hopsenn.com/styles/theme/theme.f8d33e.css">

⚙️ Notes & Behavior

The manifest is fetched only once per server process and cached in memory.
If a key is missing or the CDN is unreachable, the tag will output a helpful comment like:
```

```

The expected file structure on your CDN is:

/manifest.json
/styles/<name>/<filename-from-manifest>
