A simple Django Url Shortener.

django-link-shortener

django-link-shortener is a Django app for creating time-limited and usage-capped short URLs.

Features

• Generate short links for URLs.
• Time-sensitive links (configurable lifespan).
• Usage-limited links (configurable maximum uses).
• Per-user override of default settings via Django admin.
• Test endpoint for easy shortcode creation during development.
• Character set for shortcodes excludes I, i, 1.

Usage

1. Install with pip install django-link-shortener

2. Add shortener to your INSTALLED_APPS setting:

   INSTALLED_APPS = [
       ...
       'shortener',
   ]
   

3. Include shortener.urls in your project urls.py:

   path('s/', include('shortener.urls')),
   

4. Run python manage.py migrate to create the shortener models.

5. Use shortener.create(user, link) to generate a shortcode.

   from shortener import shortener
   
   user = User.objects.first()
   shortener.create(user, "https://example.com")
   

6. To expand the shortcode use shortener.expand(shorlink_id), or visit http://127.0.0.1:8000/s/<shortcode>/.

Test Endpoint

1. To enable the test endpoint, add the following to settings:

   SHORTENER_ENABLE_TEST_PATH = True
   

2. Start the development server and visit http://127.0.0.1:8000/s/test/<my-url-here> to create a test shortcode.

3. Visit http://127.0.0.1:8000/s/<shortcode>/ to be redirected
