# Task synopsis

I'd like to implement a URL shortener, mocking the de-facto `urlshortener` project, but with the following requirements:

# Task requirements

* We should implement it with python 3.8+, with minimum dependencies, in a single .py file. Using no 3rd party libraries/frameworks is the best.
* The configs should be passed as a single JSON file, containing these keys:
  * `base_url` - the base URL to use for the shortened URLs
  * `short_length` - the length of the shortened URLs
  * `api_key` - the API key to use this shortener to create new shortened URLs
  * ... other configs, if you think are necessary, ask me.
* The API should be RESTful, and simple enough to be used by a human.
* The shortened data should be stored within a sqlite database.
* Other than the .py file, provide a docker compose file to run it. Remember to keep the data in a mount dir so it won't be lost.
