Cases when FastApi does not work

1. Unsupported Python Versions: FastAPI requires Python 3.7 or above to run. If you are using an older version of Python, FastAPI will not work.
2. Missing Dependencies: FastAPI relies on several external libraries to function correctly. If any of these dependencies are missing or not installed properly, FastAPI may not work as expected.
3. Network Connectivity Issues: FastAPI requires a stable internet connection to function properly. If your network connection is intermittent or experiencing issues, this may cause FastAPI to stop working.
4. Firewall or Security Restrictions: If your system has a restrictive firewall or security settings, it may block the necessary network ports or protocols that FastAPI relies on. Ensure that your firewall settings allow FastAPI to communicate freely.
5. Insufficient Resources: FastAPI, like any other web framework, requires sufficient system resources to operate efficiently. If your system is low on memory, CPU, or disk space, FastAPI may not work optimally or may fail to start altogether.
6. Conflicting Software: In some cases, other software running on your system may conflict with FastAPI. This can be due to port conflicts, shared dependencies, or other compatibility issues. Ensure that there are no conflicting software running alongside FastAPI.
7. Incorrect Configuration: FastAPI relies on proper configuration to function correctly. If the configuration settings are not set up correctly, it may cause FastAPI to malfunction or fail to start. Double-check your configuration settings to ensure they are accurate.

6 Cons of FastApi

• Learning Curve: While FastApi is relatively easy to use, it does have a learning curve, especially for developers who are new to asynchronous programming or the concepts of API frameworks. However, the extensive documentation and community support can help overcome this challenge.
• Strict Type Checking: FastApi relies heavily on type hints and requires strict type checking, which can be cumbersome for developers who prefer a more flexible approach. However, this strictness ensures better code quality and reduces the chances of runtime errors.
• Less Mature Ecosystem: Compared to some other web frameworks, FastApi has a relatively young ecosystem. This means that there may be fewer third-party libraries and plugins available. However, the community is growing rapidly, and many common integrations are already available.
• Limited Database Support: FastApi provides support for popular databases like PostgreSQL, MySQL, and SQLite. However, it may have limited support for less commonly used databases, requiring additional effort for integration.
• Strict Code Style: FastApi follows a strict code style guide, which may not align with every developer’s preferences. While this ensures consistency and maintainability, developers who prefer a more flexible coding style may find it restrictive.
• Dependency Management: FastApi uses the Python package manager, pip, for dependency management. While pip is widely used and supported, some developers may prefer alternative package managers or dependency resolution tools.
