hudson2010

Hello guys ,
I have set up some project , but I have som e bit of challenge with serving static files with the plug module

23:03:44.817 [debug] GET /home
 
23:03:44.817 [debug] Sent 200 in 32µs
 
23:03:44.849 [debug] GET /priv/js/test.js
 
*23:03:44.849 [debug] Sent 404 in 24µs*
==============================
Routes :
plug(Plug.Logger, log: :debug)
	plug :match
	plug :dispatch
	plug Plug.Static, at: "/home", from: :server, only: ~w(js css images robots.txt)

	get "/" do
		send_resp(conn, 200, "Hello There!")
	end

	get "/about/:user_name" do
		send_resp(conn, 200, "Hello, #{user_name}")
	end

	get "/home" do
		conn = put_resp_content_type(conn, "text/html")
		send_file(conn, 200, "priv/index.html")
	end

I need some guidance on what , I be doing wrong , your assistance will be much appreciated

You should use the Plug.Static plug before the :match and :dispatch plugs.

Hello ,
This is the snippet of the code

defmodule PlugEx.Router do
	use Plug.Router
	use Plug.Debugger
	plug(Plug.Logger, log: :debug)
	plug :match
	plug :dispatch
	plug Plug.Static, at: "/", from: :server, only: ~w(js css images robots.txt)

	get "/" do
		send_resp(conn, 200, "Hello There!")
	end

	get "/about/:user_name" do
		send_resp(conn, 200, "Hello, #{user_name}")
	end

	get "/home" do
		conn = put_resp_content_type(conn, "text/html")
		send_file(conn, 200, "priv/index.html")
	end


	match _, do: send_resp(conn, 404, "404 error not found!")
end

  plug :match
  plug :dispatch
  plug Plug.Static, at: "/", from: :server, only: ~w(js css images robots.txt)

must become

  plug Plug.Static, at: "/", from: :server, only: ~w(js css images robots.txt)  
  plug :match
  plug :dispatch

Plug.Static serves assets from priv/static. Move your JavaScript file to priv/static/js

for the index page

<!DOCTYPE HTML>

<html manifest="">
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">

    <title>ElixirTest</title>
    <!-- The line below must be kept intact for Sencha Cmd to build your application -->
    <script  type="text/javascript" src="static/js/test.js" ></script>
</head>
<body>
	Elixir- 5
</body>
</html>

So from the above where is the issue

Your src in the script tag should just be /js/test.js
