<> = FastAPI = * https://fastapi.tiangolo.com/ 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 {{{#!highlight sh # uv An extremely fast Python package and project manager, written in Rust. # https://docs.astral.sh/uv/getting-started/installation/ curl -LsSf https://astral.sh/uv/install.sh | sh pipx install uv pip install uv uv self update pip install --upgrade uv uv add "fastapi[standard]" pip install fastapi[standard] # Virtual Environment: Python's built-in venv module # Dependency Management: requirements.txt or pyproject.toml }}} {{{#!highlight python from fastapi import FastAPI app = FastAPI() @app.get("/") def read_root(): return {"Hello": "World"} @app.get("/items/{item_id}") def read_item(item_id: int, q: str | None = None): return {"item_id": item_id, "q": q} }}} Run {{{ uv run fastapi dev }}} == pip , venv steps == {{{#!highlight sh cd ~/Documents mkdir -p fastapi-test cd fastapi-test mkdir static templates python3 -m venv .venv source .venv/bin/activate cat << 'EOF' > requirements.txt fastapi[standard] pyyaml jinja2 EOF pip install -r requirements.txt cat << 'EOF' > templates/index.html {{ titulo }}

Este é o lado Web Server do FastAPI.

Experimenta os outros caminhos:

EOF cat << 'EOF' > main.py import yaml from fastapi import FastAPI from fastapi.responses import Response app = FastAPI() @app.get("/") def read_root(): return {"message": "Hello world!"} @app.get("/openapi.yaml", include_in_schema=False) def get_openapi_yaml(): openapi_json = app.openapi() openapi_yaml = yaml.dump(openapi_json, sort_keys=False) return Response(content=openapi_yaml, media_type="text/yaml") EOF fastapi dev main.py # /home/vitor/Documents/fastapi-test/.venv/bin/python3 \ # /home/vitor/Documents/fastapi-test/.venv/bin/fastapi dev main.py # http://127.0.0.1:8000 # Server started at http://127.0.0.1:8000 # OpenAPI/Swagger documentation at http://127.0.0.1:8000/docs # http://127.0.0.1:8000/openapi.yaml # http://127.0.0.1:8000/openapi.json uvicorn main:app --reload }}}
