Enable CORS

Since we'll be using Angular served from a different port we'll need to enable CORS in our server.

Open the src/main.ts file and call the app.enableCors() method:

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.enableCors();
  await app.listen(3000);
}
bootstrap();

You can now send Cross Origin Request from your Angular app to your Nest.js without any problems. In production, you may want to disable CORS
