Objective

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints. It is built on top of Starlette for web routing and Pydantic for data validation and serialization, offering a highly efficient and intuitive way to build APIs.

Outcome:

Overall, learning FastAPI can be beneficial for developers as it offers a modern, high-performance, and easy-to-use framework for building APIs with Python, making it ideal for a wide range of use cases.

Here are five real-world scenarios where FastAPI can be useful:

1. Building microservices: FastAPI’s high-performance capabilities make it a great choice for building microservices that need to handle a large number of requests efficiently.

2. Developing backend for web applications: It provides an easy-to-use framework for building the backend of web applications, enabling developers to quickly create robust and scalable APIs.

3. Creating machine learning models APIs: FastAPI’s simplicity and performance make it an excellent choice for creating APIs to serve machine learning models, allowing for efficient predictions and handling of large datasets.

4. Building real-time applications: With its asynchronous capabilities, FastAPI is well-suited for building real-time applications such as chat applications, collaborative tools, or live dashboards.

5. Prototyping and proof of concepts: FastAPI’s simplicity and ease of use make it an ideal framework for quickly prototyping and developing proof of concepts, allowing developers to iterate and validate ideas rapidly.
