Hologram: unable to make router work

Hey @sreyansjain,
I noticed that the layout module is commented out in your page. This is required. Hologram will raise a compilation error if a page doesn’t have a layout specified - is this the actual code you use?
The layout needs to include the Hologram.UI.Runtime component which handles rendering the runtime and page JS bundles. Without the Runtime component, your page won’t be properly initialized.

Yes, its the actual code I am using
I have added the layout module

defmodule Insta.MainLayout do
  use Hologram.Component
  
  alias Hologram.UI.Link
  alias Hologram.UI.Runtime
  
  def template do
    ~H"""
    <!DOCTYPE html>
    <html lang="en">
      <head>
        <meta charset="utf-8" />
        <title>My Blog</title>
        <Runtime />
      </head>
      <body>
        <nav>
          <Link to={Insta.HomePage}>Home</Link>
        </nav>
        <main>
          <slot />
        </main>
      </body>
    </html>
    """
  end
end

I have uncommented the layout section in the page home.ex

defmodule Insta.HomePage do
  use Hologram.Page
  # alias Insta.Components.PostPreview
  
  route "/"
  
  layout Insta.MainLayout
  
  def init(_params, component, _server) do
    posts = [
      %{id: 1, title: "First Post", excerpt: "This is my first post"},
      %{id: 2, title: "Second Post", excerpt: "Another great post"}
    ]
    
    put_state(component, :posts, posts)
  end

  def template do
    ~H"""
    <h1>Welcome to my Blog</h1>
    
    <div class="posts">
      {%for post <- @posts}
        <p>{post.title}</p>
      {/for}
    </div>
    """
  end
end

There are no compilation errors. Also there were no compilation errors before adding the layout.

I dont get any routes.

When i do

mix holo.routes

I get

19:13:58.847 [info] Hologram: compiler finished
--------------------------------------------------------------------------------
ROUTE / MODULE / SOURCE FILE
--------------------------------------------------------------------------------

If I run the project there are no compilation errors, but there are no routes

[info] GET /
[error] #PID<0.2725.0> running Phoenix.Endpoint.SyncCodeReloadPlug (connection #PID<0.2724.0>, stream id 1) terminated

Were are the routes defined? In the page itself?

Looks like you forgot to add something to your app. Please make sure that you follow installation instructions especially the parts of endpoint and router:

If this is just a hobby/tinkering project, can you share the GitHub repo?

Its just a new phoenix project with nothing in it except what should go in for hologram.

mix phx.new insta --no-html --no-live --no-ecto

You can download here

I rechecked. I think I have followed the steps mentioned. There’s no error on compiling.

Thanks, the problem is that you added your app dir outside the lib dir. If you want it to work that way you need to add the app dir to Elixir compile paths:

in your mix.exs:

defp elixirc_paths(:test), do: ["app", "lib", "test/support"]
defp elixirc_paths(_), do: ["app", "lib"]

Works. Actually I saw the app folder in the hologram/test/features project so i thought code needs to go in the app folder, but overlooked the paths.

Thank you so much for your time.

No worries, happy tinkering
