title: Module Config Example description: Example demonstrating configurable module patterns — forRoot + forFeature, per-module configuration isolation, shared GreeterTool

@loopstack/module-config-example

Demonstrates configurable module patterns (forRoot + forFeature) and per-module configuration isolation using a shared GreeterTool.

By using this example you'll get...

• A reusable GreeterModule with global defaults via forRoot
• Multiple consumer modules overriding config independently via forFeature
• A nested passthrough module (GreeterAgentModule) that forwards feature config

Installation

npm install @loopstack/module-config-example

Then register the module in your app:

import { StudioApp } from '@loopstack/common';
import { ModuleConfigExampleModule } from '@loopstack/module-config-example';
import {
  DefaultGreetingWorkflow,
  FrenchGreetingWorkflow,
  GermanGreetingWorkflow,
  NestedGreetingWorkflow,
} from '@loopstack/module-config-example';

@StudioApp({
  title: 'Module Config Example',
  workflows: [DefaultGreetingWorkflow, GermanGreetingWorkflow, FrenchGreetingWorkflow, NestedGreetingWorkflow],
})
@Module({
  imports: [ModuleConfigExampleModule],
})
export class MyAppModule {}

How It Works

The exported ModuleConfigExampleModule wires four scenarios:

1. DefaultGreetingModule uses global defaults from GreeterModule.forRoot(...).
2. GermanGreetingModule overrides to German with forFeature(...).
3. FrenchGreetingModule overrides to French and runs alongside German to prove isolation.
4. NestedGreetingModule receives config through a wrapper module to demonstrate nested pass-through.

Each workflow calls the same greeter tool and writes the resulting greeting to a MessageDocument.
