How I quickly debug assigns inside heex templates
<pre><%= inspect assigns, pretty: true %></pre>
This prints the assigns in a structured manner that is easy to visualise with the pretty assigned to true, ending up with something like:
%{
socket: #Phoenix.LiveView.Socket<
id: "phx-GBsoIaUcSHDIE-sH",
endpoint: MyAppWeb.Endpoint,
view: MyAppWeb.DashboardLive.Index,
parent_pid: nil,
root_pid: #PID<0.12156.0>,
router: MyAppWeb.Router,
assigns: #Phoenix.LiveView.Socket.AssignsNotInSocket<>,
transport_pid: #PID<0.12148.0>,
...
>,
