What is implemented?

• importing products from a CSV file
• basic UI feedback
  • successful imported, and the number is displayed
  • none will be imported from an empty CSV file
  • none will be imported from a invalid CSV format
• tests
  • unit tests
  • controller tests

What is not implemented? (Further developing ideas)

• cleanup the unused APIs and tests created on Phoenix initialization.
• Transactions. What if some insertions fail during the execution?
• CSV validating. There are duplicated part_number rows in test/fixtures/data.csv. In most cases, this would be a manual mistake. Should we reject it?
• Allow users to delete products not presented in the CSV, as the task mentioned. Maybe I can implement it as follows:
  • import products as present
  • select all unique part_number in the CSV
  • delete all products not in part_numbers above
• UI tests
• credo for linting
• CI config (maybe overkill for this project but can't live without it. I used git hooks locally.)
