Ideas on how to customise the layout?

[thbar]

Thanks for phoenix_playground, I find it very entertaining & useful at the moment!

This issue is a bit of a brain dump / raw user feedback, so bear with me!

I'm trying it on a MVP, and I need to customise the layout (add some custom CSS via Tailwind & a couple of similar stuff).

I made a couple of attempts.

The relevant code is at the moment there:

• https://github.com/phoenix-playground/phoenix_playground/blob/main/lib/phoenix_playground/layouts.ex
• https://github.com/phoenix-playground/phoenix_playground/blob/main/lib/phoenix_playground/routers.ex

I cannot see how to customise it without a fair amount of refactoring, so I looked for another solution.

layout can be set at mount time:

https://hexdocs.pm/phoenix_live_view/live-layouts.html#application-layout

But this is apparently only for layout, so it leaves no room to customise root_layout if I read correctly.

@wojtekmach do want to support customisable layouts ultimately?

Thanks!

I've worked around this (for now) by putting everything in the layout without any root_layout 😄

@thbar Just ran into this limitation. Possible to share a code example of how you achieved this? I am trying to pre-load Shoelace (webcomponents library) and Tailwind CSS, both from the CDN, into my page. I think that can be achived only with root_layout

At this point I have only used this trick:

defmodule DemoLive do
  use Phoenix.LiveView

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

  # SNIP
end

and before that:

defmodule MyLayout do
  use Phoenix.Component

  def render("live.html", assigns) do
# SNIP

Hope this helps!

I've been using this method for single live views and it's simple and works well. Can import anything else you like in the same way.

  def render(assigns) do
    ~H"""
    <script src="https://cdn.tailwindcss.com"></script>
    <div class="flex justify-center items-center h-screen bg-black">
    </div>
    """
  end

I was initially trying to emulate this method from the original lib which isn't currently implemented:
