Elixir Application (part 2)

[@YBWang-pi9qq]

Awesmoe! Please make more tutorials. This channel deserve much more attention. I learned an effective processes of building SW. I used to be confused about TDD, and your demo proved that it just so simple, easy, natrual and enjoyable.

Would you rather use an Agent instead of another GenServer for the PostalCode.Cache? Also, would you recommend something like redis to take into account that almost any application server can have a single location for a cache in case there is more than one server? Or does OTP provide anything for that? Thanks a lot for all your tutorials. Unbelievably good.

[@JagaSantagostino]

So good! Great tutorials thanks

Super useful!

When will you do part 3!

[@tamasvarga9862]

There is a flaw in the validation of the area codes. Integer.to_string removes the zeros from the start of the number, so the app won't work with any area codes that begin with zeros and are given as integers (in your code none of the test cases begin with zeroes). I had to circumvent the problem like this: postal_code = cond do String.length(postal_code) == 3 -> "00" postal_code String.length(postal_code) == 4 -> "0" postal_code true -> postal_code end

Nice tutorial. However, around time-mark 12:30 everything went wrong and I can't seem to figure out what happened. Didn't know where to go to get some help to get past 12:30 and finish your tutorial. Where can I post the errors I received while trying to compile the program at this point?

[@omgneering]

The error is expected at this point. If it's something different, send the error or a screenshot to [e-mail] and we'll figure it out

[@Lafret17]

any hope for parts 3 and 4? :(
