## Overview

This Django REST Framework API manages authors, books, members, and loans. A client request enters through the project URL configuration, is dispatched by the library routes to endpoint handlers, and is serialized against Django models backed by SQLite. The API includes author and book CRUD/listing, author details with books, member details with borrowed and returned books, loan creation/listing, and loan returns. The excerpts show route dispatch and handler-to-model/serializer use; database configuration is visible, but runtime ORM database operations are implicit in Django rather than explicit calls in the excerpts.

Main entry points: [`library/urls.py`](https://github.com/govendrasahu01/library_management_api/blob/main/library/urls.py) (Library Routes), [`library/serializers.py`](https://github.com/govendrasahu01/library_management_api/blob/main/library/serializers.py) (API Serializers), [`library/models.py`](https://github.com/govendrasahu01/library_management_api/blob/main/library/models.py) (Library Models), [`library/views.py`](https://github.com/govendrasahu01/library_management_api/blob/main/library/views.py) (Author Operations)
