I am very new to the Phoenix Framework. All I am trying to do is to get the input text from an html input, which is supposed to be a message in a chat. Then I want to add that text to the chat history below.

I don’t need changesets, databases and I think I don’t even need forms (?). All I want to do is get the input and concatenate it to an ever longer chat log.

My code so far:

defmodule ChatWeb.ChatLive do 
    use ChatWeb, :live_view
    
        def mount(params, session, socket) do
            {:ok, assign(socket, :text_value, "")}
        end
        
        def render(assigns) do
        ~H"""
            <h1>Chat</h1>
            <label>Your Text:<input id="msg" type="text" /></label>
            <button phx-click="send-msg">Send</button>
            <div id="chat">
                Chat history: <%= @text_value %>
            </div>
            
        """
        end
        
        def handle_event("send-msg", _, socket) do
            msg = "what do I do here?"
            {:noreply, assign(socket, :text_value, msg)}
        end
        
end

Thanks so much in advance!
