Initialize Module

🧩 Defining the Messaging Module

To use @nestjstools/messaging in your application, you need to register the MessagingModule in your root module (usually AppModule). This will make the messaging functionality available across all other modules in your app.

🔧 Starter Setup

import { Module } from '@nestjs/common';
import { MessagingModule, InMemoryChannelConfig } from '@nestjstools/messaging';


@Module({
  imports: [
    MessagingModule.forRoot({
      buses: [
        {
          name: 'my-channel.bus',
          channels: ['my-channel'],
        },
      ],
      channels: [
        new InMemoryChannelConfig({
          name: 'my-channel',
        }),
      ],
      debug: true,
    }),
  ],
})
export class AppModule {}

📌 Notes

• MessagingModule.forRoot(...) registers the messaging system globally, meaning you don't need to import it in feature modules.

• You must define at least one bus and one channel.

• InMemoryChannelConfig our app will works on in-memory message transport layer.

• Setting debug: true enables verbose logging to help with debugging message flow.

🚀 What’s Happening Here?

Property	Description
buses	Defines logical buses for message routing.
channels	Configures message channels (e.g., in-memory, Kafka, etc.).
debug	Enables or disables debug logging.
my-channel	A simple in-memory channel used by the message.bus.

⚠️ Important: Make sure this is defined in your AppModule or the main/root module to ensure messaging is globally available.
