Starting with LiveView

A basic Live module has a mount/3 function which has the params, session data and socket of the connection and the render/1 function which renders the template:

defmodule LiveViewAppWeb.CounterLive do
  use Phoenix.LiveView

  def mount(_params, _session, socket) do
    {:ok, assign(socket, :counter, 0)}
  end

  def render(assigns) do
    ~L"""
    <label>Counter: <%= @counter %></label>
    <button phx-click="incr">+</button>
    """
  end
end

To create a live context keeping in mind a timeline of posts:

mix phx.gen.live Timeline Post posts username body likes_count:integer reposts_count:integer

Twitter like app

• Created a basic application with a CRUD of posts.
• Broadcast reloading to all the sessions when creating and updating posts.
• Updating with temporary assigns to optimization.
