Today I Remember - Flask vs FastAPI

Over the past couple of years people have asked a number of times why I keep choosing FastAPI over Flask. I should add a caveat that I am pretty much entirely Python based. So, when it comes to production ready APIs and such. FastAPI is my go-to.

Why FastAPI over Flask then? FastAPI is a modern, fast, and efficient framework that offers a wide range of features that make it an ideal choice for building high-performance web applications.

One of the key advantages of FastAPI is its use of modern Python features, such as type hints and asynchronous programming, which can help you write more concise, maintainable, and scalable code. FastAPI also includes a powerful dependency injection system, which makes it easy to manage complex application dependencies and ensures that your code is easy to test and maintain.

In addition, FastAPI includes built-in support for popular data serialization formats, such as JSON and MessagePack, and offers seamless integration with popular data storage systems, such as databases and caches. This makes it easy to build efficient and scalable web applications that can handle large volumes of data with ease.

Overall, if you’re looking for a web framework that offers high performance, easy scalability, and a wide range of features, you might want to give FastAPI a try. Its modern Python features, powerful dependency injection system, and seamless data storage integration make it a great choice for building production-ready web applications.
