Description

Lifecycle hook interface for initialization logic.

Implement this interface to execute custom initialization code when a provider instance is created by the DI container. The $onInit method is called automatically after the instance is constructed and dependencies are injected.

Usage

import {Injectable, OnInit} from "@tsed/di";

@Injectable()
class MyService implements OnInit {
  async $onInit() {
    // Initialize database connection, load configuration, etc.
    await this.connect();
  }
}

$onInit

$onInit(): Promise<any> | void;
