This - now obsolete - repo contains the original implementation of a simple web application that shows the arrivals boards for the selected TfL stops (https://arrivalsoflondon.co.uk).
This is code no longer in use as it was rewritten in Typescript React with a Go back-end.
This application is not intended for any kind of actual use, at least not yet. It is a learning exercise, where I experiment with technologies used in Python web applications such as Flask, SQLite, SQLAlchemy, Bootstrap and others.
If you'd like to use any part of it, you're welcome to do so. Just be careful, some parts of the code are probably still rubbish.
