A little nicknack for myself so that I can time, to the minute, my walk to the station for my commute home!
It sneaks a look at the CityMapper API, using the same call by their superduper Super Router to see what trains are due to leave a specified station.
The script then filters out only trains that stop at my home station. The script also lists how many minutes walk away the station is using the Google Maps Distance Matrix API.
This is my very first forray into Ruby. I've since learnt that there are many rubyisms that I haven't exploited but the script is so short and self-explanitory, I don't feel it needs a refactor just yet. I quite like how simple Sinatra is to get going - very impressive.
