Shurl is a simple URL shortener written in Python and relies in Flask.

1. Install needed packages: pip install -r requirements.txt
2. Run the app: python ./app.py

By default, the app will run in http:https://127.0.0.1:80, base URL will be http:https://127.0.0.1 and debug will be turned off.

The app creates a file called .config in the app's directory with the default values. The configuration parameters are the following:

• host: Address where the app will listen. Defaults to 0.0.0.0 (all interfaces)
• port: Port where the app is served. Defaults to port 80.
• base_url: The base URL for shortened URLs. Defaults to http:https://127.0.0.1.
• debug: Enable debug mode. Defaults to False.

Invalid parameters will default to the values above and trigger a warning.

This file gets parsed to a dict at the start of the app. In order to apply changes to the configuration, the app must be restarted.

It takes the 5 first characters of the SHA256 of the URL, and stores it in a file called urls.txt, which is located in the app's directory. The URLs file format is the following:

<key> <url>

Where key is the 5 first characters of the SHA256 hash and url is obviously, the URL. This file gets parsed at the start of the app to a dict. When a key is not 5 characters long, it will be ignored.
