Creating an App with MSDN App Services

Step 1: Initialize Your Project

Navigate to your project directory in the terminal and initialize a new app service project using the MSDN CLI:

msdn app create my-new-app --template basic

This command creates a new application named my-new-app using the basic template.

Step 2: Configure Your App Settings

Open the appsettings.json file in your project's root directory. Here, you can configure various aspects of your application, such as:

• Database connection strings.
• API keys for third-party services.
• Environment-specific configurations.

Here's an example configuration:

{
  "Database": {
    "ConnectionString": "Server=your_server;Database=your_db;User Id=your_user;Password=your_password;"
  },
  "ApiKeys": {
    "ExternalService": "your_api_key_here"
  }
}

Step 3: Define Your App Logic

The core of your application resides in the src/controllers and src/services directories. Create your API endpoints and business logic here.

For example, a simple API endpoint in src/controllers/helloController.js:

// src/controllers/helloController.js
import { Controller, Get } from '@msdn/app-services';

@Controller('/hello')
export class HelloController {
    @Get('/')
    getGreeting() {
        return { message: 'Hello from MSDN App Services!' };
    }
}

Step 4: Register Dependencies

If your application uses custom services or components, register them in the src/app.js file using the dependency injection container.

// src/app.js
import { App } from '@msdn/app-services';
import { HelloController } from './controllers/helloController';
import { MyCustomService } from './services/myCustomService';

const app = new App();
app.register(HelloController);
app.register(MyCustomService); // If you have a custom service
export default app;

Step 5: Build and Deploy

Once your application logic is in place, build your project and deploy it to the MSDN App Services platform.

To build:

msdn app build

To deploy:

msdn app deploy production

Replace production with your desired deployment environment.
