Alexander CS Hendorf: 5 Things about fastAPI I wish we had known beforehand

FastAPI is a popular web framework for building APIs with Python. Here are 5 things about fastAPI that we wish we had known beforehand:

1. Automatic Interactive API documentation: One of the key features of fastAPI is that it automatically generates interactive API documentation based on the code you write. This can be incredibly helpful for testing and debugging your API endpoints.
2. Performance optimization: FastAPI is designed for high performance, with asynchronous request handling and automatic code optimization. Understanding how to leverage these features can help improve the speed and efficiency of your API.
3. Dependency injection: FastAPI makes it easy to use dependency injection to manage complex dependencies in your application. This can help keep your code clean and organized, and make it easier to test and debug.
4. Cookiecutter templates: FastAPI provides cookiecutter templates for quickly setting up new projects. Using these templates can help streamline the development process and ensure that your project follows best practices.
5. Security considerations: Like any web framework, security is a key consideration when using fastAPI. Understanding best practices for securing your API endpoints and handling sensitive data is essential to avoid potential security vulnerabilities.

Overall, fastAPI is a powerful and flexible framework for building APIs with Python. By understanding these key aspects of the framework, you can make the most of its features and build robust and efficient APIs.
