Type Alias IDeinitizable

IDeinitizable: { deInit(): Promise<void> }

Deinitialization contract for objects requiring async cleanup. Implementers provide a way to tear down/finalize state after use.

Counterpart to IInitizable - called during application shutdown. Ensures graceful cleanup of resources: connections, file handles, listeners.

Usage patterns:

  • Database connection pools: close all connections, flush pending queries
  • Caches: persist data, close backend connections
  • Servers: stop listening, close client connections
  • Event listeners: unregister, cleanup memory
  • Locks: release held resources

Typically called once during application shutdown, before process exit. Should be idempotent when possible (calling deInit() multiple times is safe).

Type declaration

  • deInit:function
    • deInit(): Promise<void>

    • Deinitializes the object. Performs any async cleanup required to shut down gracefully. Should release resources and finalize internal state.

      Returns Promise<void>

      Void promise (resolves when deinitialization complete)

      Throws

      Error if deinitialization fails (should log but not block shutdown)
