Framework lifecycle

Booting

Tempest's entry point is usually public/index.php or ./tempest. The former uses HttpApplication, the latter ConsoleApplication.

When created, the application boots by creating the FrameworkKernel:

• it loads the environment, the exception handler, and configures the container,
• it then starts discovery through the LoadDiscoveryLocations and LoadDiscoveryClasses classes,
• and finally registers configuration files through the LoadConfig class.

When bootstrapping is completed, the Tempest\Core\KernelEvent::BOOTED event is fired.

Shutdown

The shutdown process is managed by the kernel's shutdown() method, which is called at the end of both HTTP and console lifecycles, as well as in exception handlers. This method:

• runs deferred tasks,
• dispatches the KernelEvent::SHUTDOWN event,
• performs any necessary cleanup,
• and terminates the application process.
