Class: AppBooted

Defined in: packages/core/src/events/FrameworkEvents.ts:155

Emitted once when the application finishes booting — all providers registered and booted and conventions wired. durationMs is the wall-clock boot time, so observers (Health page, telemetry, logger) can surface startup cost.

Example

FrameworkEvents.on(AppBooted, (e) => {
  console.log(`booted in ${e.durationMs}ms (${e.providerCount} providers)`);
});
