Q & A

What is FastAPI and what is it used for?

FastAPI is a Python framework designed for developing APIs. It acts as a bridge between the frontend and backend of an application, allowing easy interaction with databases, data manipulation, and handling business logic. It helps create endpoints that manage data exchange between the server and the client.

Do I need to know Python to use FastAPI?

Yes, you need to know Python at least at a basic level to use FastAPI effectively. FastAPI is built on Python, so understanding the language is crucial for implementing functionality like endpoints and handling backend logic.

How does FastAPI compare to other Python frameworks like Django?

Unlike Django, which comes with built-in tools and a defined project structure, FastAPI is more lightweight and flexible. It doesn’t impose a project structure, allowing developers to integrate any libraries they prefer for database management, caching, and authorization.

What types of projects can be built using FastAPI?

FastAPI can be used to build a wide range of applications, from simple microservices to large-scale services with millions of lines of code. It is versatile and can be applied to both small projects (which can be developed in just a couple of days) and long-term enterprise applications.

Who are the typical users of FastAPI?

FastAPI is widely used by backend developers, machine learning specialists, data scientists, and testers. It’s particularly valuable for those working with APIs, databases, and backend logic in Python, with a growing demand in various industries.

Why is FastAPI in high demand in the job market?

FastAPI is in high demand because it is fast, asynchronous, and highly efficient compared to older frameworks like Django and Flask. It’s also easy to learn, making it a go-to choice for companies developing modern, scalable, and high-performance applications.

What makes FastAPI asynchronous, and why is this important?

FastAPI is asynchronous, meaning it can handle multiple requests concurrently, making it faster than synchronous frameworks. This allows businesses to reduce infrastructure costs and process more requests with less hardware, which is crucial for high-traffic applications.

What is the role of FastAPI's auto-generated documentation?

FastAPI provides automatic API documentation through a web interface that is generated as you create endpoints. This feature makes it easy for developers to visualize, test, and debug their APIs, providing real-time documentation for endpoints, parameters, and responses.

How long does it take to learn FastAPI compared to mastering full backend development?

Learning FastAPI itself can take just a week or two, as it is lightweight and easy to grasp. However, mastering backend development (including working with databases, caching, and optimizing APIs) requires much more time, typically several months.

What salary range can developers expect if they know FastAPI?

Backend developers with FastAPI knowledge typically earn between 60,000 to 100,000 rubles for mid-level roles, with junior developers earning around 60,000 rubles. Senior developers can earn from 180,000 to 500,000 rubles, depending on experience and company.
