URL Shortener With FastAPI and Python

In this tutorial, we have built a fully functional FastAPI-driven Python web app that creates shortened URLs that forward to target URLs. URLs can be extremely long and not user-friendly. This is where a URL shortener can come in handy. A URL shortener reduces the number of characters in a URL, making it easier to read, remember, and share.

• Swagger UI
• Python 3
• FastAPI
• SQLite
• SQLAlchemy
• Uvicorn server

• Installation(s)

(venv) $ python -m pip install fastapi==0.75.0 uvicorn==0.17.6(venv) $ python -m pip install sqlalchemy==1.4.32(venv) $ python -m pip install python-dotenv==0.19.2(venv) $ python -m pip install validators==0.18.2

• .env file

ENV_NAME="XXXXXXXX"BASE_URL="http://127.0.0.1:XXXX"DB_URL="sqlite:///./XXXXXXXXXX.db"

i. Clone the git repo

https://github.com/AAdewunmi/URL-Shortener-FastAPI-Python.git

ii. Open project folder

iii. Explore

😎

i. Open project in preferred IDE. I'm using PyCharm.

ii. Run the live server using uvicorn.

(venv) $ uvicorn shortener_app.main:app --reload

• Create SQLite database

When the server restarted, sqlalchemy automatically created your database in the location that you defined in your DB_URL environment variable. If you used sqlite:///./shortener.db as the value of DB_URL, then there should be a file named shortener.db in the root directory of your project now. That’s your SQLite database!

iii. Open "http://127.0.0.1:8000/docs" in any web browser
