Traditional vs. Headless WordPress Debugging Methods
TRADITIONAL HEADLESS
WP_DEBUG_DISPLAY 👉 Enable WPGraphQL Debug Mode & inspect response errors
die() / wp_die() / var_dump() 👉 wp_send_json() or Enable GraphQL Debug Mode and use graphql_debug()
Postman/REST client 👉 Enable GraphiQL IDE
WP_DEBUG_LOG 👉 Still works!
Xdebug on page load 👉 Xdebug triggered by GraphiQL request in the wp-admin
Query Monitor 👉 Enable GraphQL Query Logs
NewRelic/Profiling tools 👉 Enable GraphQL Tracing
