Events

Events in Semitexa PHP: sync, deferred and queued handlers, domain event dispatch, request pipeline events and Server-Sent Events (SSE) streams.

• Execution Arena

  Launch the same backend intent in sync, Swoole async, and queued modes, then watch the proof arrive over SSE.

• Sync Events

  Dispatch an event and all sync listeners run before the response is sent.

• Deferred Handler

  Heavy work runs after the response is sent, so the user gets instant feedback.

• Queued Handler

  Events survive restarts and scale across workers, backed by a durable message queue.

• Server-Sent Events (SSE)

  Live Server-Sent Events demo: one long-lived HTTP connection streams real backend events to the browser via EventSource. No WebSockets, plain PHP.

• Ledger Demo

  Dispatch a protected demo event and inspect only the persisted demo ledger rows through a safe read-only view.

• Request Pipeline Events

  The events every request passes through (AuthCheck, AccessCheck, HandleRequest) and the Swoole server lifecycle hooks around them.

• Domain Event Dispatch and Configuration

  Choosing sync or async per handler, the HandlerCompleted event, running the async worker, and how the three event kinds compare.
