Code Review — Create CroRouter

Found 2 bugs and some style suggestions.

🐛 Bug #1: $data.pairs crashes on undefined body

lib/HTML/Component/CroRouter.rakumod:6

my %data is Map = $data.pairs;

$data is optional ($data?), defaults to Any. When no request body is sent (GET requests, or POST with empty body), calling .pairs on Any throws. Fix:

my %data is Map = $data.defined ?? $data.pairs !! ();

🐛 Bug #2: run-undefined missing $*HTML-COMPONENT-RENDERING

lib/HTML/Component/Endpoint.rakumod:72-84

run-undefined doesn't set $*HTML-COMPONENT-RENDERING = True. Without this, the wrapped methods from the %endpoint trait won't return the endpoint path — they call nextsame and execute the original method body. This means endpoints on class methods won't generate correct htmx paths during rendering.

Also, run-defined extracts $snippet.HTML at line 65, but run-undefined at line 79 assigns $component.RENDER: $snippet directly — inconsistent return handling.

Fix:

method run-undefined(|data) {
  my $component = $!class;
  my Capture $cap .= new: :hash(%(|$!capture.hash, |data.hash)), :list[|$!capture.list, |data.list];
  my $method-output = $!class."{&!method.name}"(|$cap);
  if $!return-component {
    require ::("HTML::Component::Tag::SNIPPET");
    my $snippet = ::("HTML::Component::Tag::SNIPPET").new;
    my $*HTML-COMPONENT-RENDERING = True;
    $component.RENDER: $snippet;
    $method-output = $snippet.HTML;
  }
  my $ret = &!return.(:$component, :$method-output);
  return $ret.HTML if $ret.^can: "HTML";
  $ret
}

💡 Style: &!method shadows built-in

lib/HTML/Component/Endpoint.rakumod:5

has &.method is required;

Naming an attribute .method shadows the built-in .method introspection. Consider renaming.

💡 Style: EndpointList.get fat arrow

lib/HTML/Component/EndpointList.rakumod:16

%pars.kv.map: -> $key, $value { $endpoint.matches: |%($key => $value) }

Could use colon pair: :{ :$key($value) }

✅ What's Good

• root-component + Cro route integration is clean
• EndpointList SetHash registry with .get chaining — elegant
• %endpoint trait with method wrapping for htmx — clever
• cro-todo.raku example complete and runnable
• SNIPPET tag for sub-components — smart pattern
• Already using colon pairs in &!return.(:$component, :$method-output) 👏
