This repository is DEPRECATED! Use url-shortener2 instead which is a re-written version of this repositry with Users and Authentication/Authorization baked in.

This is based on an original tutorial from Real Python which I definitely recommend checking out for a decent example of a non-trivial FastAPI app.

• Refactored the code so that each 'group' of Routes is in its own file, and moved some utility & error functions to a dedicated module. This makes the project much cleaner and easier to understand. Add tags to each group for better documentation.
• /list (GET) route to return a list of all the URL's in the database along with their target.
• /{url_key}/peek (GET) route to show the target url of the specified url_key, without actually redirecting there. Allows users or front-end client to check the URL before visiting.
• /admin/{secret_key} (PATCH) route to change the target URL of a link identified by the secret_key. The body of the request needs to have the target_url property containing the new URL which must be a valid URL
• The Root Path ("/") will return a short HTML template if viewed in a Web Browser, JSON otherwise.
• Choose either the default SQLite database or Postgresql from the .env file.
• The URL Key is case-sensitive, so added lowercase letters to the mix for extra availability. Now the key will randomly include upper, lower and numbers.

Non-exhaustive list of planned additions, in no specific order.

• Option to add a delay to the redirect, showing the exact target URL and giving the option to Cancel.
• User-friendly Front-end (probably in React) for adding and editing URLs.
• Protected ability to purge all is_active: false URLs
• Custom URL key - allow user to use their own key instead of the autogenerated one.
• Add Users and Auth, replace the current 'SECRET_KEY' method of dealing with ownership.

This is done using the .env file in the root folder. See .env.example for details:

ENV_NAME="Development"
BASE_URL="http://127.0.0.1:8000"

# Comment/Uncomment your choice of database. If Postgreql, the other 5 variables
# below need to be also filled. Will default to SQLite if none selected.
DB_BACKEND="sqlite"
# DB_BACKEND="postgresql"

# location and name of SQLite database, if used.
DB_URL="sqlite:///./shortener.db"

# Postgresql stuff if selected above.
DB_NAME="<YOUR_DB_NAME>"
DB_ADDRESS="<YOUR_DB_ADDRESS>"
DB_PORT="<YOUR_DB_PORT>"
DB_USER="<YOUR_DB_USER>"
DB_PW="<YOUR_DB_PASSWORD>"

Install the required dependency packages :

pip install -r requirements.txt

Run a local development server from the project root using Uvicorn :

uvicorn shortener_app.main:app --reload
