Next.js and Django JWT Authentication | Part 1 – Backend API
In this article, we will be discussing how to implement JWT Authentication in a backend API using Next.js and Django. JSON Web Tokens (JWT) is a popular method for securely transferring information between parties. It is commonly used for authentication and authorization in web applications.
Setting up the Django Backend
The first step is to create a Django backend with support for JWT Authentication. We will start by installing the necessary packages using pip. Open a terminal and navigate to your Django project folder. Run the following command to install the required packages:
pip install djangorestframework djangorestframework-jwt
Once the packages are installed, you will need to configure Django to use these packages for JWT Authentication. Modify your settings.py file to include the following configurations:
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': (
'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
),
}
Creating the User Authentication Endpoints
With the backend configured for JWT Authentication, the next step is to create the endpoints for user authentication. Create a new app within your Django project and define the views for user registration, login, and logout. Here’s an example of how these views might look:
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.permissions import AllowAny
from rest_framework_jwt.settings import api_settings
jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER
jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER
class RegisterView(APIView):
permission_classes = (AllowAny,)
def post(self, request):
# Implement user registration logic here
return Response({"message": "User registered successfully"})
class LoginView(APIView):
permission_classes = (AllowAny,)
def post(self, request):
# Implement user login logic here
user = request.user
payload = jwt_payload_handler(user)
token = jwt_encode_handler(payload)
return Response({"token": token})
class LogoutView(APIView):
def post(self, request):
# Implement user logout logic here
return Response({"message": "User logged out successfully"})
These views handle user registration, login, and logout using JWT Authentication. Once these endpoints are created, your Django backend is now set up to support JWT Authentication and user authentication.
In Part 2 of this series, we will integrate the Django backend with a Next.js frontend application to create a fully functional web application with JWT Authentication.
Let me know in the comments what sort of content you're most interested in:
– tutorials on something specific (Next.js/Django/Redis/Docker/etc.)
– how to build certain apps (e-commerce/social media/real-estate/clones of other apps/etc.)
– overview of how something works (authentication/app architecture/deployment/etc.)
– other (career/learning/habits/energy/procrastination/focus/etc.)
Also one thing I'm thinking is to have things outside of just tutorials on this channel, could be interesting to dive into some topics like the ones in the last point. I like putting together tutorials, but also don't want to just be a tutorial channel.
Let me know your thoughts on some of these things!
Hi, one quesiton, why did you decide to use Djoser isntead of something like django-rest-auth?
you are the best tutor on youtube the next project will be mobile otp authentication ecommerse project
Hey Bryan, by setting AUTH_COOKIE_SAMESITE = 'None', wouldn't that make it vulnerable to CSRF attacks? How could we avoid this in this case, if we still want to use all methods, including POST, for example? Is it possible to combine this jwt cookie approach with csrf token? If so, how could we do that? Thanks, man!
This is GOLD! Finally someone who knows their Django!
I've traced back over all the steps, the only thing I've found to be missing is setting the refresh and access expiration on djangos end, as currently it appears to be stuck at its default value, have checked through both the git and the video.
I wish there was this with Laravel 😢
I don't understand how you got only 260 likes. It is by far the best tutorial I have watched on the topic !
having ads at the middle of a video is pretty annoying
Months later this is still one of the best, if not the best tutorial on this topic by far! Hope you are well Bryan!
couldnt you build this only using nextjs? im confused on why you need django as well, isnt nextjs a full stack framework?
Love your tutorial, a question….
How can I make so that the users without verified identities on AWS can register in my Django website?
hi can i use django sesion instead of django cookies,which is more secure thanks….lot thanks
I have been checking out Django Rest API and have noticed the heavy usage on the serializers file can you explain why you dont use serializers and when they are needed?
guys, the logout view is throwing this "'type' object is not iterable" error and I can't figure out which class object is trying to iterate.
How can I view my tables in pgadmin? I look at the tables for the postgres db but nothing shows up? I am using docker to containerize django, celery, redis, postgres. Can I not view my db because of this?
Hi brayan, i follow this tutorial but i got 500 response when ever i try to create user but the user data is store in the database. i set up everything correctly.
please videos on micro services would be perfect
I really appreciate this 😊
hi! is there a way for the custom auth model, to show up on the admin panel? currently having trouble getting the the users to show up on the admin panel, thanks!
