We will use Django to set up our backend and Django REST Framework (DRF) for our API creation. The easiness of performing development tasks (eg. user authentication, URL routing, and schema migration) attracts our attention. Also, Django with PostgreSQL provides many benefits: 1. Some data types in Django will only work with PostgreSQL; 2. Django offers django.contrib.postgres to operate on PostgreSQL; 3. Django supports many features of PostgreSQL. Moreover, Django is compatible with Redis.
