# ExPress

Use markdown folders as a source for page content.
Cache on *write* and serve from ETS.

TODO: Write proper readme

## Setup

Add it to your deps in `mix.exs`

```elixir
    {:ex_press, "~> 0.0.13"},
```

Point it to the directory with your markdown files.

```elixir
# config/runtime.ex
config :ex_press, ExPress.Store,
  directory: "path/to/content/folder"
```


```elixir
defmodule MyAppWeb.PageLive.Show do
  use MyAppWeb, :live_view

  @impl true
  def render(assigns) do
    ~H"""
      <main>
        {@page.html |> raw()}
      </main>
    """
  end

  @impl true
  def handle_params(%{"slug" => slug}, uri, socket) do
    # or use ExPress.get_by_slug(slug, true) to bypass ETS cache.
    case ExPress.get_by_slug(slug) do
      {:ok, page} ->
        {:noreply, socket 
          |> assign(page: page)
          |> assign(page_title: page.metadata["title"] || "Untitled")
          # Get all pages in the store:
          |> assign(pages: ExPress.Store.list_contents())
        }
        
      :error ->
        {:noreply, 
         socket
         |> put_flash(:error, "Page not found: #{slug}") 
         |> push_navigate(to: "/")}
    end
  end
end
```

And mount it in your router

```elixir
# lib/my_app_web/router.ex
live "/*slug", PageLive.Show
```
