Skip the HTTP layer for workers and CLI with createApplicationContext()

src/worker.ts

typescript

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { ReportService } from './reports/report.service';

async function bootstrap() {
  const app = await NestFactory.createApplicationContext(AppModule);
  const reports = app.get(ReportService);
  await reports.generateDaily();
  await app.close();
}
bootstrap();

`createApplicationContext()` boots the DI container without starting an HTTP server. For cron jobs, queue consumers, and one-off CLI scripts you get every provider, guard-free, with no wasted listener or port. It's the right entry point for anything that isn't serving requests — you keep Nest's module structure and injection while avoiding the overhead and surface area of a web server you never use.
