By Robert Alford, this tutorial aims to build a Progressive Web Application (PWA) with Django as the backend API and Angular as the frontend interface. The project focuses on building a simple trivia game that combines the best aspects of both web and native apps. In part one, the author builds the backend API using Python and Django, including setting up a local Django project, creating models for questions and answers, and defining serializers to serve data in JSON format. The API endpoint is then configured to work with CORS headers to facilitate cross-origin communication with an Angular frontend application.
