British Rail Fares Engine Build Status

The British Rail Fares Engine is a library, API and user interface that can be used to return Britsh rail fares.

It relies on data from Rail Delivery Group. The rules around journey/fare validity are very specific to British rail and are not useful for other data sets.

It does not test the validity of journeys as it has no concept of a journey but it does provide a number of filters that can be applied without a journey:

  • CalendarRestrictionFilter checks if the ticket code has any calendar restrictions
  • AdvancePurchaseFilter checks the Advance Purchase booking horizon has been met
  • RailcardBanFilter checks whether there is a blanket ban on the railcard for a given date
  • SuppressedFareFilter removes non-derivable fares that are used to suppress flow fares
  • TicketTypeDateFilter checks the ticket type start, end and quote dates

Some rules like the validity codes return dates are in-built to the FareService.

Testing

npm test

Setup

It is assumed that MySQL is installed locally and there is a database called fares set up. The database credentials can be overriden by setting environment variables DATABASE_USERNAME, DATABASE_PASSWORD, DATABASE_HOST DATABASE_NAME.

npm run data 

Run

Starting the service will load some data into memory (~30 seconds) and then start the service on port 8002. Browsing http://localhost:8002 will display the test user interface.

npm start
