See /packages/di/src/common/fn/lazyInject.ts.

Overview

function lazyInject<Token>(factory: () => Promise<{
    default: TokenProvider<Token>;
}>): Promise<Token>;

Description

Lazily load and inject a provider from a dynamic import.

Loads the provider module asynchronously, registers it if needed, calls $onInit if present, and returns the resolved instance. Useful for code splitting and lazy loading dependencies.

Usage

import {lazyInject} from "@tsed/di";

// Lazy load a service
const service = await lazyInject(() => import("./HeavyService"));

// Use in a method
async loadPlugin() {
  const plugin = await lazyInject(() => import("./plugins/MyPlugin"));
  return plugin.initialize();
}

default

default: TokenProvider<Token>;
