Phoenix is awesome.

A problem I ran into lately is how to add additional static paths to be served.

If you take a look in your lib/endpoint.ex file, you'll see the plug used for adding static paths:

plug Plug.Static,
  at: "/", from: :electronify, gzip: false,
  only: ~w(css fonts images js favicon.ico robots.txt)

I wanted to add another folder to be served, 'zips', that I had to edit the only: line in the plug specification as such:

plug Plug.Static,
  at: "/", from: :electronify, gzip: false,
  only: ~w(css fonts images js favicon.ico robots.txt zips)

There you have it, now I can access the files in the zips folder in priv/static/zips through the URL. Cheers!
