Django API without DRF: What are the consequences - django

I'm not sure what might go wrong when I have to integrate a django API (built using JsonResponse and without extra frameworks) with a frontend, in this case, Next.js.
I built a django API using JsonResponse (void of DRF). I want to build a frontend client with Next.js that would make API calls to my django API. My questions are:
Will I have to run both django and next.js servers at the same time to execute the full project?
I think I would face some challenge with csrf token, what other challenges may I face having built my API without an API framework as Django Rest Framework?

It is almost always a better approach to treat these two as separated as possible. I'd go with completely separate repos, hosting etc...
I think the biggest advantage of using DRF is the validation. DRF has nice ways to handle request data validation. Your views will look much leaner, because it will save you the trouble of writing much boilerplate code.

General questions about Django and DRF

I've made a project using Django and Bootstrap (I plan to use React for the frontend). Then I started building REST API with DRF and it seems that my DRF views are pretty similar (if not duplicative) to my original Django views such as DetailView, UpdateView and etc.Now I wonder if I can keep my old views or should I completely replace them with DRF ones? Or should I use DRF views for CRUD and keep particular Django views?
And another qusetion: am I right that when working with Django and DRF Django becomes just an ORM provider also responsible for business logic, authentication and some other features?
Thanks.
Django is a fullstack web development framework. Here you can progress in different ways. You can use Django and ReactJS without having to develop any RestAPI. It depends on how you approach it with ReactJs.
Do you want to develop the frontend entirely with ReactJS? If so, you can develop your backend directly using DRF and consume APIs on the frontend only with React.
While developing a full stack with Core Django, if you want to make the Frontend dynamic, you can use Django and DRF together, or you can develop APIs without using DRF.
You can use DRF and Core Django together for different scenarios, or you may only need one of them. It depends on you and your project.
Edit for second question:
Django Rest Framework requires Django. Also, with Django you can do everything DRF does. By writing more code of course. This process provides many conveniences with DRF; like authentication modules, json serializers..

Django Rest Framework and the Frontend

I want to use Django Rest Framework as an API and am looking for a way to "couple" the frontend / HTML/CSS/JS to it.
To put it in perspective, I am used to the way Django "usually" does it, by naming HTML templates and 'rendering' them when going to a particular URL.
Now, with DRF, it appears that this functionality has fallen away and everywhere I look it's just "react.js or vue.js" as the answers to consume the API.
What are my options for the front end? Can I not just do it all within the 'usual' Django framework, simply, as it was done before. And why do no resources talk about this?
Thanks, let me know if you require further info.
DRF is just additional layer for Django which help to implement API. You can use Django for render html on server side and serve it to browser. You don't need use DRF for it. But if you assume that you frontend app will be interactive, dynamic and complicated then it is not best way to solve it.
More popular approach suggest to separate it on frontend application (react or vue) and backend with REST API for interact with. It allow move all things related with UI on frontend app and only keep state on server.
By the way Django was developed for generate html on server and for site like this https://www.washingtontimes.com/news/ but world changing. Resources talk just about popular things

Reason to use Postman for Django Rest Framework

I'm used to test Django Rest Framework apps with the test tools available directly in Django and DRF. It's possible to setup a dummy client and expose all the REST methods.
At the same time, I see many posts talking about Postman for API testing. I fail to see where the advantage would be.
Is there any reason for me, a single developer, to use Postman? Or perhaps there is only an advantage for shared projects?

Advantages of using REST API framework over simple URL and view creation in Django?

It might be a silly question for many, but why can't I instead
Create a view in django that takes a request and returns HttpResponse in, say, JSON format
Map the view to a URL
Hit the URL from my browser or another server and use the result?
Thanks.
EDIT - Two approaches: Import some djangorestframework or tastypie and build an api in my application which will throw json responses VS building a view and tell it to return json response. Is there any huge advantage of using the first one?
I think you could make the same argument about any extension library. It just depends on how much you want to rebuild and what the existing library has that would be beneficial to your project.
Many times I've created custom endpoints without an API library when working with ajax requests inside my project. For that instance, using an API package is overkill. But for having a full API server, Django rest framework offers a lot of functionality.
Sure, you can make views that do what you suggested. But at some point are you going to want to authenticate through an HTTP request? Are you going to want to filter? Are you going to want to make permissions, or just have all endpoints open? Are you going to want to protect against CORS?
You can kind of go down the list of all the features of an API library and ask these questions about what you want to accomplish with your project. If you're working with any type of external application and your django project is just for an API server, usually it's best to go with Rest Framework. If you just have some one-off endpoints to receive ajax requests, usually you just want to build custom endpoints.

using backbone/ember makes django being a simple REST API?

I have read a couple of articles about using new JS frameworks like Backbone.js or Ember.js
I have come up to this statement:
If I use a JS framework like Backbone.js/Ember.js, I then move the logic from the back-end (Django) to the front-end.
Therefore, will Django actually be used only for its Models?
Does that mean that Django Views and Django Template are not needed anymore and the Django back-end is kinda turn into a "basic" REST API that will be consumed by the front end.
Do you agree? Is it then the purpose of Django in this case?
Is turning the django backend into a REST API one of the most suitable use case when using a framework like Backbone.js/Ember.js for the front-end?
Thanks.
Django is perfectly fine to be used this way, you still get the admin, the models, the orm and all the third-party plugins. However, it isn't blazingly fast, so if you're doing simple document level, non-relational REST mapping, you might wan't to look into node.js and mongoDB for instance.
If you're sticking with django (like we are, we like the structure it gives us), you can use one of the REST plugins:
Django Rest Framework A perfect match since DRF 2.0, under very active development!
Django Tastypie (checkout backbone-tastypie.js for integration)
Django Piston (might be a bit stale or has development picked up lately?)
If you only want to work with frontend development, checkout the Backend-as-a-Service places like cloudmine.me or firebase.com that handle all backend stuff for you, for a price of course.
Django may seem unnecessary once you start thinking about single page solutions and Javascript applications, but if you want your site to be 'fail proof' it wouldn't be impossible to develop both a client side Javascript version of the site as well as a backend django side incase the user, or your site's javascript, fails at some level. Of course this requires creating your site twice, and probably isn't needed in the age of modern browsers, but such would be one of the few instances where you would mix the two for a complete solution.
Yes, that's about it. You can use it to manage authentication to resources and such and maybe use a main view for your application but you won't need to use the server side templating since these frameworks are made to work with json/xml response.
That's why a lot of people are moving to lighter backend/backbone or ember combo instead of a complete solution like django. You can also use your django for caching json response which makes your application appears faster.
We are doing that and use django-piston to make it easier on you.
Normally you make your entire website under Django and only one page will be a "single app page" using backbone.js, usually that page is a very interactive page, with lots of small updates that occur frequently and need to be shown very fast to the user. This page, because of the large number of changes and user interactions is constructed on the client-side so that you are using his PC resources and not the server's, the rest of the pages can use django because it offers you a very stable and secure framework for the server-side
