I have a project where I might be doing what you’re asking: rendering HTML from fragments of eex stored in JSON files.

Here is the code we’re using:

alias Phoenix.LiveView.Engine, as: LiveViewEngine
alias Phoenix.LiveView.HTMLEngine

def render_markup(markup) do
  quoted_code = EEx.compile_string(markup, engine: HTMLEngine)
  
  {evaluated, _} =
    Code.eval_quoted(quoted_code, [assigns: []],
      aliases: component_aliases(),
      requires: [Kernel],
      functions: [
        {Phoenix.LiveView.Helpers, [live_component: 1, live_file_input: 2]}
      ]
    )
  
  LiveViewEngine.live_to_iodata(evaluated)
end

let me know if it’s helpful!

Something like this:

<.button color={:primary} outline={true} text="Save" type="button"/>

We use it for our liveview storybook: https://storybook.phenixgroupe.com

Can you elaborate on this? Where are the templates stored that they cannot be compiled?
