I’m happy to announce a new project, Phoenix Playground, the easiest way to build single-file Phoenix apps.

Here is an example:

Mix.install([
  {:phoenix_playground, "~> 0.1.0"}
])

defmodule DemoLive do
  use Phoenix.LiveView

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

  def render(assigns) do
    ~H"""
    <span><%= @count %></span>
    <button phx-click="inc">+</button>
    <button phx-click="dec">-</button>

    <style type="text/css">
      body { padding: 1em; }
    </style>
    """
  end

  def handle_event("inc", _params, socket) do
    {:noreply, assign(socket, count: socket.assigns.count + 1)}
  end

  def handle_event("dec", _params, socket) do
    {:noreply, assign(socket, count: socket.assigns.count - 1)}
  end
end

PhoenixPlayground.start(live: DemoLive)

See Announcing Phoenix Playground blog post for more information and check out the GitHub repo. I’m looking forward to hearing what you are building with this.

Happy hacking!
