NestFactory.createApplicationContext run successfully but never exit. How to shutdown app gracefully?

[janckerchen]

I love this idea so much, Thanks to that, you can take advantages of the Nest framework everywhere, including CRON jobs and even build a CLI on top of it., but stuck.

create app context and invoke marketService.test()

import { NestFactory } from "@nestjs/core";
import { ApplicationModule } from "../../src/app.module";
import { TradeModule } from "../../src/trade/trade.module";
import { MarketService } from "../../src/trade/services";

const run = async () => {
    const app = await NestFactory.createApplicationContext(ApplicationModule);
    const marketService: MarketService = app.select(TradeModule).get(MarketService);
    marketService.test();
}

run();

marketService.test() log message successfully, but script never exit. how can I use i in CRON?

maybe mongoose open database connection and not closed properly.
mongoose.connection.close() don't do the trick. how to shutdown app gracefully?

I have the same problem with cron job.
Version of nest is 5.1.0, but NestFactory.createApplicationContext never exit

[dilame]

Now I have the opposite problem. My main.ts contains

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

async function bootstrap() {
  await NestFactory.createApplicationContext(AppModule);
}
bootstrap();

Inside my app module i create moleculer instance that connects to Redis and waiting for incoming events, but 10 seconds later i have

Process finished with exit code 0

It is not expected behaviour.
@kamilmysliwiec what can i do to avoid this?

I use close method，but it don't work

export async function getApp () {
  return NestFactory.createApplicationContext(AppModule)
}

const app = await getApp()
// do someting
app.close()
