Public Health England (PHE) publishes Coronavirus confirmed cases data by upper tier local authority daily on this page: https://www.gov.uk/government/publications/coronavirus-covid-19-number-of-cases-in-england/coronavirus-covid-19-number-of-cases-in-england
This little python script gets the page data through the GOV.UK Content API and saves it as a .csv file inside the data folder, using the timestamp YY-MM-DD. The data is parsed every day around 19:00 GMT.
EDIT: Of course the data gets withdrawn a few days after I start collecting it and replaced by a proper dashboard. Oh well, I'll still leave this up as an example of how to setup Travis CI to regularly push data to a repo.
