[erlang-questions] how to better organize code for a website

[avinash D'silva]

Hi,


I am using cowboy+cowboy_session for building websites.

each route has something similar as shown below:


-module(get_pageX).
-behaviour(cowboy_http_handler).

-export([init/3]).
-export([handle/2]).
-export([terminate/3]).

-record(state, {
}).

init(_, Req, _Opts) ->
{ok, Req, #state{}}.

handle(Req, State=#state{}) ->



      case  cowboy_session:get("loggedin",  Req) of

         true ->
                       #do something here

          _ ->
                    #not logged in.

       end,



{ok, ReqFinal} = cowboy_req:reply(200,
[{<<"content-type">>, <<"text/html">>}],
        <<"Some response">>,
          Req),

{ok, ReqFinal, State}.

terminate(_Reason, _Req, _State) ->
ok.


The above CASE(code) is repeated for every route to check if the user is
logged in, is there a better way to organize this?

what I am looking for is a way to check if the user is logged in and if
not, redirect to login route.


PS: I am new to Erlang
