Section Overview
Async
Synchronous and deferred event flows, queues, and SSE-style interactions.
Support Semitexa
Built for developers who prefer control over magic.
Your support helps keep it fast, open, and evolving.
Route Map
Each feature page pairs live output with the source that produced it.
Event Flow
5Async
Execution Arena
Launch the same backend intent in sync, Swoole async, and queued modes, then watch the proof arrive over SSE.
Async
Sync Events
Dispatch an event and all sync listeners run before the response is sent.
Async
Deferred Handler
Heavy work runs after the response is sent — the user gets instant feedback.
Async
Queued Handler
Events survive restarts and scale across workers — backed by a durable message queue.
Async
SSE Stream
Real-time server push without WebSockets — connect once and receive real backend events over plain HTTP.
