Server-Sent Events
summary
A proof-of-concept implements Server-Sent Events using a PHP 8 backend (Symfony 5.4) and a React frontend with Symfony Mercure as the hub. It publishes Update objects through HubInterface, supports public and per-user topics, integrates with the command/listener action engine, includes tests that mock the hub for ~80% backend coverage, and demonstrated handling of about 50–100 concurrent clients in load checks while noting limits on binary data and per-tab connections.
