How enable CORS on Django REST Framework?

Using django-cors-headers, whose documentation says to install the library

pip install django-cors-headers

and then add it to your installed apps:

INSTALLED_APPS = (
    ...
    'corsheaders',
    ...
)

You will also need to add a middleware

 MIDDLEWARE = [
    ...,
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    ...,
]
CORS_ALLOW_ALL_ORIGINS = True # If this is used then `CORS_ALLOWED_ORIGINS` will not have any effect
CORS_ALLOW_CREDENTIALS = True
CORS_ALLOWED_ORIGINS = [
    'http://localhost:3030',
] # If this is used, then not need to use `CORS_ALLOW_ALL_ORIGINS = True`
CORS_ALLOWED_ORIGIN_REGEXES = [
    'http://localhost:3030',
]
