Subresources, the easy way with API Platform 3
summary
Shows how API Platform 3 replaces fragile APISubresource hacks with explicit scoped operations (uriTemplate + uriVariables + Link) so /teams/{teamId}/players returns scoped IRIs and avoids order-dependent behavior via itemUriTemplate. Demonstrates NotExposed operations for REST-required but hidden endpoints, an experimental CreateProvider that injects parent resources into POST bodies (POST /teams/{teamId}/injuries), using a dedicated /seats endpoint to fix N+1, and the uriTemplate on APIProperty plus canonical_uri_template and 3xx redirection to normalize alternate resource URIs.
