Fastapi- Pros & Cons
Excerpt
### Cons of FastAPI Even though FastAPI offers numerous perks, developers may find some limitations and challenges. #### Syntax Learning Curve Although it has many benefits, the framework leverages a unique syntax that boosts the learning curve for web developers unfamiliar with standard Python-type hints or asynchronous programming. Learning the tool or enforcing the data model through Pydantic requires time. #### Messy Main File FastAPI normally centralizes everything within the main.py file, which can result in maintenance and crowding issues, especially when the project grows. In that case, your team must enhance code organization by making dedicated files for router inclusion and exception handlers. #### Bounded ORM Support Even though some frameworks support object-relational mapping (ORM) or ORMs like Tortoise ORM and SQLAlchemy, other frameworks provide improved integration with ORM to smooth the database and application. #### Confusing Error Handling A confusing error-handling method makes it difficult for developers to debug and troubleshoot problems. This can lead to longer debugging in complicated applications with various error scenarios. ## Contact Us Today Need assistance in building a web application through FastAPI?
Related Pain Points
Code organization becomes unwieldy as projects scale
5FastAPI tends to centralize everything in the main.py file, causing crowding and maintenance issues. Teams need to manually create dedicated files for exception handlers and router inclusion to maintain code organization.
Steep learning curve for async programming and type hints
5FastAPI's specific syntax and reliance on asynchronous programming, standard Python type hints, and Pydantic increases the learning curve significantly for developers unfamiliar with these concepts, potentially slowing onboarding and adoption.
Limited ORM integration compared to other frameworks
5While FastAPI supports ORMs like SQLAlchemy and Tortoise ORM, integration is not as smooth as other frameworks. Developers must manually choose, configure, and ensure async compatibility with their ORM of choice.
Error handling mechanism is unintuitive and confusing
4FastAPI's error-handling mechanism is occasionally confusing, making troubleshooting and debugging challenging. Complex applications with multiple error scenarios experience longer debugging times as a result.
