htmx.config.sse ~ htmx

The htmx.config.sse option is a configuration object for Server-Sent Events (SSE) behavior.

Default:


{
  reconnect: false,
  reconnectDelay: 500,
  reconnectMaxDelay: 60000,
  reconnectMaxAttempts: 10,
  reconnectJitter: 0.3,
  pauseInBackground: false
}

Properties

reconnect - Auto-reconnect on disconnect
reconnectDelay - Initial delay in ms before reconnecting
reconnectMaxDelay - Maximum delay in ms (uses exponential backoff)
reconnectMaxAttempts - Maximum reconnection attempts
reconnectJitter - Jitter factor (0-1) to randomize reconnect timing
pauseInBackground - Pause SSE streams when tab is not visible

Example


htmx.config.sse.reconnect = true;
htmx.config.sse.reconnectDelay = 1000;
