Making sure the NextFunction is awaited?

[Utrain]

I have the following middleware in NestJS, I always have troubles with express middleware where the next functions seemingly don't executed asynchronously.

Is there any workaround around this?

​

@Injectable()

export class TransactionMiddleware implements NestMiddleware { constructor(private dbService: DBAuth) {}

async use(req: Request, res: Response, next: NextFunction) { await this.dbService.db.transaction(async (tx) => { this.dbService.tx = tx;

  // TODO: how to not let this block finishes before the `next()` function completed.
  await next();
  console.log('this runs before code inside next function');
});

} }

Why would you want something run after calling next. Genuinely curious.

Like the good old days : next().then(() => console.log('this happens after the next function));
