Create your first REST API in Django Rest Framework

Django Rest Framework

Python, one of the most popular programming languages ​​today, is used for almost every subject in the field of informatics. Although we often hear the name of Python in the fields of artificial intelligence and data analysis, the use of Python is not limited to this. Especially when developing the REST API, Python’s Django Rest Framework provides developers with many conveniences.

What is Django Rest Framework

Django Rest Framework is an advanced framework that allows developers to code a common backend for both mobile applications, web applications, and desktop applications. For example, you can use a backend server that you coded with Django Rest Framework both in your mobile application and in your web application.

You can develop your applications by using Django Rest Framework with frontend technologies such as Angular, React, Vue. Since Django Rest Framework gives responses in a common structure in programming, you can use these outputs either with Angular or with React. So what type of output are these? Structures like JSON, of course. You can send these printouts in different structures upon request, of course, to the front end.
