Writing the User Registration Feature

Learn to implement the user registration feature using JWT authentication.

Now that we are done with the user application, we can confidently move on to adding a login and registration feature to the project.

Before accessing protected data, the user needs to be authenticated. This comes with the assumption that there is a registration system to create an account and credentials.

JWT authentication

To make things simpler, if the registration of a user is successful, we will provide credentials, here JWTs, so the user won’t have to log in again to start a session—a win for user experience.

Note: We have already installed the djangorestframework-simplejwt authentication plugin for DRF to handle JWT authentication. Please look at the Appendix for more details.

Before working with this package, there are some configurations needed in the settings.py file. We need to register the app in INSTALLED_APPS and specify DEFAULT_AUTHENTICATION_CLASSES in the REST_FRAMEWORK dictionary:
