I think the usual way is that your backend (api) will run on a separate server than your frontend and you make CORSCORS requests. Therfore you have to set the CORS-Header correctly. This is quite simple using django-cors-headers. 

#settings.py
INSTALLED_APPS = (
    ...
    'corsheaders',
    ...
)

MIDDLEWARE_CLASSES = (
    ...
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    ...
)

CORS_ORIGIN_ALLOW_ALL = True  # allows all 
# or use whitelist:
CORS_ORIGIN_WHITELIST = (
    'google.com',
    'hostname.example.com'
)

If you develop for a website only, you could run frontend and backend on the same server. but if you develop a mobile app you can’t install and run django on the phone.
