django-frontend-settings 2.0.0

Expose feature flags and settings from django waffle and django constance in an endpoint.

Abstract

This project provides an API that expose settings and feature flags for the frontend.

It uses django-drf to create an endpoint to expose flags and settings configured in django-waffle and django-constance

Usage

Requirements Python (3.6, 3.7, 3.8, 3.9) Django (2.2, 3.0, 3.1, 3.2)

Installation

Install using pip:

pip install django-frontend-settings

Add ‘frontend-settings’ to your INSTALLED_APPS setting.

INSTALLED_APPS = [
    ...
    'frontend_settings',
]

Expose the view in your urls:

from frontend_settings.views import settings as frontend_settings_view

url(r"^frontend-settings/", frontend_settings_view, name="frontend-settings"),

Then your flags from waffle and setting from constance should be returned on a get in this route:

$ curl 'http://localhost:8000/frontend-settings/'
{"data":{"flags":{"MY_FEATURE_FLAG":true},"settings":{}}}

In that case I had FRONTEND_MY_FEATURE_FLAG flag in waffle. The default prefix for flags is FRONTEND_, if you like to change it you can do by changing the following config on settings.py:

FRONTEND_SETTINGS = {
    "WAFFLE_FLAG_PREFIX": "FRONTEND_", # Prefix used to filter out the flag that should be exposed in the endpoint
    "CONSTANCE_KEY_PREFIX": "FRONTEND_", # Prefix used to filter out the settings in constance
}
