Modules

Modules are the basic building blocks of a Nodecord application. Every application has at least one root module, and can be composed of many feature modules.

Defining a module

import { Module } from '@nodecord/core';
import { PingCommand } from './ping.command';
import { DatabaseService } from './database.service';

@Module({
    imports: [DatabaseModule],
    providers: [DatabaseService],
    handlers: [PingCommand],
})
export class AppModule {}

Module options

Option	Description
imports	Other modules whose exported providers are available in this module
providers	Services and other injectables registered in this module's container
handlers	Command and event handler classes

Global modules

Marking a module as global registers its providers in the shared global container, making them available to every other module without importing:

@Module({ providers: [ConfigService], global: true })
export class ConfigModule {}

Scoped containers

Each module gets its own Inversify container scoped as a child of the global container. This means providers from a parent module are visible to its children, but not the other way around.
