This was for one of my several abandon projects so it never grew. At one point I had my personal site in LiveView until I decide to switch over to Hugo. This is what I landed on but it didn’t have time to grow. It’s based off of @al2o3cr’s first suggestion suggested along with a component. I just build up segments are two-tuples with {segment, path}.
As this is old code I’m not going to look over it to see if I’m embarrassed by it or not as I might not post it 
# In a Utils module
@doc """
Taks a path and return a list of tuples in the form of:
{"segment", "/path/to/segment"}
## Example:
iex> segment_path("/path/to/segment")
iex> [{"path", "/path"}, {"to", "/path/to"}, {"segement", "/path/to/segment"}]
This is useful for making breadcrumbs.
"""
def segment_path(path) when is_binary(path) do
path
|> String.split("/", trim: true)
|> Enum.scan([""], &[&1 | &2])
|> Enum.map(&{hd(&1), Enum.join(Enum.reverse(&1), "/")})
end
# In a components module
def breadcrumbs(assigns) do
admin_path = String.replace(assigns.current_path, ~r/\A\/admin/, "")
breadcrumbs = segment_path(admin_path)
breadcrumbs = [{"dashboard", ""} | breadcrumbs]
last = List.last(breadcrumbs)
assigns = assign(assigns, :breadcrumbs, breadcrumbs)
~H"""
<div class="cursor-default">
<%= for {name, path} <- @breadcrumbs do %>
<span class="after:content-['/'] after:text-gray-500 last:after:content-['']">
<%= if {name, path} == last do %>
<%= String.capitalize(name) %>
<% else %>
<.redirect to={"/admin#{path}"}><%= String.capitalize(name) %></.redirect>
<% end %>
</span>
<% end %>
</div>
"""
end
Ok, I did look it over. It’s a little more complex than it needs to be for a show-and-tell but the admin specific stuff is because I was only using them in the admin section. segment_path/1 is the main thing. This was pre-verified routes and one of the reasons I was excited about them.
EDITED: Man, I really didn’t re-read this thread before posting. Sorry for the repeated context.
