Looking to create a simple function in Phoenix

The alias of the endpoint… Something like YourAppWeb.Endpoint. This module would be in file lib/your_app_web/endpoint.ex

Oh… by the way, test files are not compiled, First they are in test folder, second exs are for elixir script files and are not meant to be compiled.

Rename it to ex, put it in lib and it will be compiled…

Some people add a lib/mock folder, where they put tests/seeds files.

defmodule Test do
 
  def broadcast(message) do
    Test.Endpoint.broadcast!("room:lobby", "new_msg", %{body: message})
  end
end

I cant seem to find the correct alias. So this file is located in lib/test.ex , which is not located in the lib/test_web folder. I believe I am calling Endpoint the wrong way because it is still saying its undefined, I cant seem to access any file in this module from the IEX , I tried using a simple IO.puts as well and it says the function is defined.

:o Should I change the name from test to practice or something? I just used the name test for example sake!

Well, what is the name You gave to your phoenix application?

I named it test!

try this

$ mix phx.new phanendery
$ cd phanendery
$ cat lib/phanendery_web/endpoint.ex

Should I do this in a new folder?

yes, as a new test project

defmodule PhanenderyWeb.Endpoint do
  use Phoenix.Endpoint, otp_app: :phanendery

  socket "/socket", PhanenderyWeb.UserSocket,
    websocket: true,
    longpoll: false

  # Serve at "/" the static files from "priv/static" directory.
  #
  # You should set gzip to true if you are running phx.digest
  # when deploying your static files in production.
  plug Plug.Static,
    at: "/",
    from: :phanendery,
    gzip: false,
    only: ~w(css fonts images js favicon.ico robots.txt)

  # Code reloading can be explicitly enabled under the
  # :code_reloader configuration of your endpoint.
  if code_reloading? do
    socket "/phoenix/live_reload/socket", Phoenix.LiveReloader.Socket
    plug Phoenix.LiveReloader
    plug Phoenix.CodeReloader
  end

  plug Plug.RequestId
  plug Plug.Telemetry, event_prefix: [:phoenix, :endpoint]

  plug Plug.Parsers,
    parsers: [:urlencoded, :multipart, :json],
    pass: ["*/*"],
    json_decoder: Phoenix.json_library()

  plug Plug.MethodOverride
  plug Plug.Head

  # The session will be stored in the cookie and signed,
  # this means its contents can be read but not tampered with.
  # Set :encryption_salt if you would also like to encrypt it.
  plug Plug.Session,
    store: :cookie,
    key: "_phanendery_key",
    signing_salt: "mvWhNNeR"

  plug PhanenderyWeb.Router
end

This was the response in the terminal to that last command

And this is your endpoint module…

The alias You should use is

PhanenderyWeb.Endpoint

Back to my orginal project , I used this as my alias

defmodule Test do
  alias TestWeb

  def broadcast(message) do
    Endpoint.broadcast!("room:lobby", "new_msg", %{body: message})
  end
end

Does this look correct? Maybe I can trying the wrong commands in the iex shell?

I seemed to have been in the wrong directory sorry for the confusion! This is my current error when I run it, believe it is the wrong alias

iex(1)> Test.broadcast("hello")
** (UndefinedFunctionError) function Endpoint.broadcast!/3 is undefined (module Endpoint is not available)
    Endpoint.broadcast!("room:lobby", "new_msg", %{body: "hello"})
