Django REST vs FastAPI

Django is a free and open-source Python web development framework used in developing websites. It was created by Adrian Holovaty and Simon Willison in 2003 and used the MVT (Model-Template-View) pattern. It's popular for its robust and straightforward nature. It’s one of the most popular frameworks and is used by Tech titans like Instagram, Youtube, etc. Django is also popular because it encourages code reusability.

Advantages of Using Django

• The Django code structure is veritably effective, making it easy for developers to add further functionalities to their websites.
• The Rest framework (Representational State Transfer can be defined as a software architectural style that defines a set of constraints to be used when creating web services) in Django, which can be achieved using Django Rest Framework. DRF is a flexible toolkit used to develop Web APIs in Django.
• REST is the general framework, while Django Rest Framework DRF is a specific REST framework used in Django. It’s easy to make Web APIs with Django because of its modular and customizable armature.
• Django emphasizes security by furnishing defense against common SQL injection and cross-site request forgery attacks.

Disadvantages

• Django’s clumsy software may limit development speed because of the numerous reusable modules.
• It also needs to make sure that previously released versions are still compatible with new releases, contributing to its slow nature.
• Django Models can have simple inheritance, but can't have mixins.
• Django uses ORM, which was created before SQLAlchemy, making Django ORM inferior to SQLAlchemy because it's less flexible.

Use Cases

Django can manage projects of any size and capacity. We can use it for simple web applications or high-performing web applications. Some of the use cases would be:-

1. High-load reserving engines
2. Shopping platforms
3. Schools/Colleges/Universities management systems
4. iOS and Android apps supporting web-based applications

Some developer features that can be enforced with Django are admin dashboards, image-based verification, emailing systems etc.

FastAPI

Fast API is an ultramodern, open- source, fast, and largely performant Python web framework used for developing Web APIs and is based on Python 3.6+ standard.

Advantages of Using FastAPI

FastAPI validates the developer's data type indeed in deeply nested JSON requests. Fast API is built on norms like JSON Schema (a tool used for validating the structure of JSON data), OAuth2.0 (it’s the industry-standard protocol for authorization), and OpenAPI (which is a publicly available API "Application Programming Interface") FastAPI makes it easy to make a GraphQL API with a Python library called graphene-python.

Disadvantages

Because FastAPI is fairly new, the community is small compared to other frameworks, and anyhow of its detailed documentation, there's veritably little external educational materials.

Use Cases

Fast API, works impeccably if your concern is speed. Netflix uses it for its internal extremity operation. It also scales impeccably in deploying production-ready Machine Learning models because ML models work best in production when they're wrapped around a REST API and deployed in a microservice.

Conclusion

As we compare both in terms of the points as:

• Packages: Django has numerous packages that enable the reusability of code. It is a full-stack web development framework, unlike FastAPI, a minimalistic framework used for developing fast web applications.
• Performance: In performance, FastAPI is speed-oriented, next to Django, which is not very fast.
• Community: Django has the most significant community because of its wide use and popularity. FastAPI, on the other hand, has a small community because it’s fairly new.
• Flexibility: Fast API is flexible and doesn't restrict users to a particular project or any code layout, whereas Django expects things to be done in a certain way unlike microframeworks, which have no opinion on how developers structure things.

In conclusion, Django is perfect if you want to build robust full-stack web applications because it has several functionalities and works very well in production. On the other hand, FastAPI is perfect if you’re looking for high-performance or scalable applications. It's always wise to choose a framework based on what types of projects you want to develop.
