Pattern matching on Cloudex.upload/2 departs from Elixir conventions? about cloudex HOT 4 CLOSED

The reason is that Cloudex.upload/2 can handle a single file, multiple files, or a directory. Thus the result you get back is a list with a result for each file it uploaded, in case that you uploaded only one file, you will get a list with one element. if you uploaded a directory for example you would get a result per uploaded file. for example :

[
      {:ok, %Cloudex.UploadedImage{...}},
      {:ok, %Cloudex.UploadedImage{...}},
      {:ok, %Cloudex.UploadedImage{...}}
    ] = Cloudex.upload("/assets/multiple")

Hope this makes sense for you :)

Thanks, that makes sense. I don't mean to nitpick, but I was curious. Another thing that peaked my interest was passing the opts to upload as a map, versus a keyword list, which you tend to see in most examples.

No problem, always ask :)

Regarding a map vs keyword list, this is mostly a personal preference. Practically a keyword list is ordered and thus makes it a lot harder to use for function head pattern matching when there are a lot of options, since you need to make sure you use the same order as the function head expects. With a map its a lot easier to match on specific elements, no matter what the order.

Great, thank you the explanations and, of course, for Cloudex. 👍
