How to serve static file in production

We use whitenoise to serve static file.

Once you install it you should add following to Middleware:

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    "whitenoise.middleware.WhiteNoiseMiddleware",
    ...
]

Then in the settings:

STATIC_ROOT = BASE_DIR / 'static'
STATICFILES_STORAGE = "whitenoise.storage.CompressedManifestStaticFilesStorage"
