Developer tickets
Extend and repair the full-stack job tracker through realistic, independent tasks.
Each ticket starts from its own copy of the finished application. Download it into a new folder, reproduce the reported behavior, and run its acceptance checks on your computer. Tickets include progressive hints and a worked solution.
All 12 tickets, starter archives, and solutions are included in Course access and the Complete Bundle. View access options.
