FastAPI
FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.
FastAPI works OK without uv. You can build, install, and run FastAPI projects using traditional tools like pip, venv, and poetry
main.py
Install
1 # uv An extremely fast Python package and project manager, written in Rust.
2 # https://docs.astral.sh/uv/getting-started/installation/
3 curl -LsSf https://astral.sh/uv/install.sh | sh
4 pipx install uv
5 pip install uv
6 uv self update
7 pip install --upgrade uv
8
9 uv add "fastapi[standard]"
10
11 pip install fastapi[standard]
12 # Virtual Environment: Python's built-in venv module
13 # Dependency Management: requirements.txt or pyproject.toml
14
Run
