Package: django-rudra
What problem does it solve?It’s a simple django package which can help developers to create APIs faster without writing views.It works quite similar to GraphQL, but it’s not GraphQL. It’s just a simple package which can help you to create APIs with url configurations only.So next time when you want to create an API, you don’t need to write views, you just need to write url configurations.Even frontend folks can create or tweak APIs without writing views.SetupInurls.py:from django.urls import path, include
