Add django-js-error-hook to your INSTALLED_APPS settings:

INSTALLED_APPS = (
        ...
    'django.contrib.staticfiles',
    'django_js_error_hook',
            ...
)

If you want to log the error in the console for development:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse'
        }
    },
    'formatters': {
        'verbose': {
            'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s'
        },
        'simple': {
            'format': '\033[22;32m%(levelname)s\033[0;0m %(message)s'
        },
    },
    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'filters': ['require_debug_false'],
            'class': 'django.utils.log.AdminEmailHandler'
        },
        'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'simple'
            },
    },
    'loggers': {
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': True,
        },
        'javascript_error': {
            'handlers': ['mail_admins', 'console'],
            'level': 'ERROR',
            'propagate': True,
        },
    }
}

By default the logger is called “javascript_error”, if you want you can define JAVASCRIPT_ERROR_ID in your settings:

JAVASCRIPT_ERROR_ID = '<your logger name>'

The view will do csrf validation - if for some reason it doesn’t work, set JAVASCRIPT_ERROR_CSRF_EXEMPT to True in your settings.

Then install the urls:

urlpatterns = patterns('',
        ...
    url(r'^js_error_hook/', include('django_js_error_hook.urls')),
    ...
)

In your template, simply add the js_error_hook script:

<script type="text/javascript" src="{% url 'js-error-handler-js' %}"></script>

Now every Javascript error will be logged in your logging error stream. (Mail, Sentry, …)
