# Hello

To start your Phoenix server:

* Install dependencies with `mix deps.get`
* Create and migrate your database with `mix ecto.setup`
* Install Node.js dependencies with `cd assets && npm install`
* Start Phoenix endpoint with `mix phx.server`

Now you can visit [`localhost:4000`](http://localhost:4000) from your browser.

Ready to run in production? Please [check our deployment guides](https://hexdocs.pm/phoenix/deployment.html).

// NOTE: The contents of this file will only be executed if
// you uncomment its entry in "assets/js/app.js".

// To use Phoenix channels, the first step is to import Socket,
// and connect at the socket path in "lib/web/endpoint.ex".
//
// Pass the token on params as below. Or remove it
// from the params if you are not using authentication.
import {Socket} from "phoenix"

let socket = new Socket("/socket", {params: {token: window.userToken}})

// When you connect, you'll often need to authenticate the client.
// For example, imagine you have an authentication plug, `MyAuth`,
// which authenticates the session and assigns a `:current_user`.
// If the current user exists you can assign the user's token in
// the connection for use in the layout.
//
// In your "lib/web/router.ex":
//
// pipeline :browser do
// ...
// plug MyAuth
// plug :put_user_token
// end

// defp put_user_token(conn, _) do
// if current_user = conn.assigns[:current_user] do
// token = Phoenix.Token.sign(conn, "user socket", current_user.id)
// assign(conn, :user_token, token)
// else
// conn
// end
// end
//
// Now you need to pass this token to JavaScript. You can do so
// inside a script tag in "lib/web/templates/layout/app.html.eex":
//
// <script>window.userToken = "<%= assigns[:user_token] %>";</script>
//
// You will need to verify the user token in the "connect/3" function
// in "lib/web/channels/user_socket.ex":
//
// def connect(%{"token" => token}, socket, _connect_info) do
// # max_age: 1209600 is equivalent to two weeks in seconds
// case Phoenix.Token.verify(socket, "user socket", token, max_age: 1209600) do
// {:ok, user_id} ->
// {:ok, assign(socket, :user, user_id)}
// {:error, reason} ->
// :error
// end
// end
//
// Finally, connect to the socket:
socket.connect()

// Now that you are connected, you can join channels with a topic:
let channel = socket.channel("topic:subtopic", {})
channel.join()
.receive("ok", resp => { console.log("Joined successfully", resp) })
.receive("error", resp => { console.log("Unable to join", resp) })
