What is the correct way to deploy a nest js app in a azure web app server? Should the package.json be included?

I created Sample nestjs App and deployed to the Azure web app (Linux) through VS code.

Thanks @Azure OSS Developer Support for Clear Explanation.

• When you deploy the nestjs app to azure, the dist folder and package.json are needed, So Entire Project needs to deploy.

Below is My complete Project Structure.

• This is because Azure Web App needs the package.json file to know which dependencies to install. Without package.json, which leads to runtime errors.

• The Nest project created listens on port 3000 by default. But in Azure Web App dynamically assigns a port number to application at runtime. This port is provided via the PORT environment variable.

So, I define the port in main.ts file as shown below.

const port = process.env.PORT || 3000;

Below is the complete code.

main.ts:

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
const port = process.env.PORT || 3000;
async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(port);
}
bootstrap();

Make sure to add the start script to the package.json as shown below.

"start:prod": "node dist/main"

In VS code select Angular Extension -> Subscription -> Azure Web App -> Deploy to Web App -> Complete Project Folder as shown below.

It is Successfully deployed to Azure Web app.
