Display data from files online

Nelisa wants weekly reports that update every day.

• Create a web application with a route like /sales/:week_name to display sales for a given week. :week_name is a variable: the route would look like this /sales/week1.
• Sales should be read from the <week_name>.csv file, which should be updated daily. The updated sales data should be visible immediately after the sales file changed.
