    1. Hi Hughie,

      Joseph here. Thanks for pointing this out.

      The “done” event is emitted by needle not csv-parser. This is what the needle documentation says.
      “The done” event is emitted when the request/response process has finished, either because all data was consumed or an error occurred somewhere in between”. There is a similar example in the docs. https://github.com/tomas/needle#event-done-previously-end

      However, using it the way I did is confusing given that the article is about “Using csv-parser to read and parse CSV files”. Someone might opt for a different HTTP client instead of needle. It is good to stick to the “end” event as you suggested to avoid confusion.

      Thanks again. Let me know if there is anything else I might have missed.
