FASTAPI
basic instance of fast api To install FastAPI, a modern Python web framework for building APIs quickly, you can use the following steps:
Create a Virtual Environment (Optional but Recommended): It's a good practice to create a virtual environment for your project to isolate its dependencies from the system-wide Python installation.
python3 -m venv myenv source myenv/bin/activate # On Windows: myenv\Scripts\activate Install FastAPI and Uvicorn: FastAPI works well with Uvicorn, an ASGI server. You can use pip to install both FastAPI and Uvicorn.
pip install fastapi uvicorn Create a FastAPI Application: Create a Python file (e.g., main.py) and write a basic FastAPI application to test that everything is set up correctly.
from fastapi import FastAPI
app = FastAPI()
@app.get("/") def read_root(): return {"Hello": "World"} Run the FastAPI Application: You can use Uvicorn to run the FastAPI application.
uvicorn main:app --reload Here, main refers to the filename main.py, and app is the instance of the FastAPI application you created in the file.
Access the API: Once the application is running, you can access it by opening your browser or using a tool like curl to make requests. By default, the application should be accessible at http://127.0.0.1:8000.
Remember that these instructions assume you're using a Unix-like system (Linux or macOS). If you're on Windows, you might need to adjust some commands (e.g., virtual environment activation). Always refer to official documentation for the most up-to-date information.
