Exercise inspired by great talk from Jay Hayes in Oscon Conf

BuildFeenix

Make exercise inspired by great talk from Jay Hayes in Oscon Conf about making simple Phoenix framework. I am not implementing here everything from talk (eg. controllers can't plug properly some others methods which are assign something to connection). I was adding extra handling POST methods and make sure the post params (not only query params) are parsed in conn.

This repo is containing pull-requests which are represent progression of evolving logic from the most simple handling request till have own separated application which is using this simple modules for build simple api server.

• #1
• #2
• #3

NOTES

• mix new build_feenix --sup

def deps do
  [
    {:plug, "~> 1.6"},
    {:cowboy, "~> 2.4"},
    {:poison, "~> 4.0"}
  ]
end

• now run YourApp.Endpoint from Application module YourApp (in your_app.ex). Set this module as aplication which should be run in mix.exs.

Router

• plug(:fetch_query_params) method from Plug.Conn which parse query params to conn object [https://hexdocs.pm/plug/Plug.Conn.html#fetch_query_params/2]
• plug Plug.Parser ... needed to parse params from request body (POST, PUT, .. methods) [https://hexdocs.pm/plug/Plug.Parsers.html#content]
• Plug.Router.Utils.build_path_match [https://github.com/elixir-plug/plug/blob/master/lib/plug/router/utils.ex#L61]
