Django REST framework

Information Technology > Web platform development

Description

Django REST framework is a powerful and flexible toolkit for building Web APIs in Python. It's an add-on to the Django web framework that provides functionalities for handling HTTP requests and responses, data serialization, authentication, permissions, pagination, and more. With the Django REST framework, developers can create robust, scalable, and secure APIs that can handle complex queries and relationships between data models. It also supports various types of views, from simple function-based views to complex class-based views, and allows for customization and optimization. Knowledge of this framework is essential for anyone looking to build APIs with Django.
