how do would we listen to multiple queues? I see we setup "main queue" but how would we import more than one queue?

[@oyinlolaolasunkanmi]

@@seanknowles783 this is a critical question and from findings, nestjs did not do a good job in covering this. The only answer I found says that you have to reacreate the microservice and include the queue one after the other.

Solid tutorial. I had no idea that microservices were so simple to set up in NestJS.

Thank you so much for doing these videos on NestJs Microservices. Really fantastic. It helps a lot if you drop the link to source code for beginners like me.

We need an in-depth course covering Nestjs microservices running on GCP, RabbitMQ & Reddis etc.. love the videos by the way :)

[@ScalableScripts]

That is the plan, in ~2-3 months this course with everything you mentioned + more will be released on my platform, so check scalablescripts.com from time to time :)

[@kunalghosh1117]

An overall tutorial is beneficial for newbies. What do I feel is that suppose we have a scenario where we need to join multiple tables/documents & fetch data then how we are going to perform it with microservices?

[@michaelabbott7139]

The same way you do in Monolithic world. Instead you use the network to resolve the request.

[@abdullahanis5761]

@@michaelabbott7139 you mean an api request from other service?

[@michaelabbott7139]

@@abdullahanis5761 yeah exactly. There’s two schools of thought here, you can make a network request to some over service to resolve the overall needs of the UI. For this scenario we can use three services Accounts service Transactions service Payments service The accounts service can make a get request using the user ID to get the list of transactions that user has made. Or we can use a message bus, that the three services are listening for events on. For example the accounts service could have a consumer listening for the CompletedTransaction event, from that consumer we can store the ‘accounts’ domain object for a transaction. Which eventually reduces the number of inter communication required by a single source to complete some business request. Effectively is a very very loose implementation of domain driven design.

Hi, when i change the package json of 8001 to listen it starts the app but postman doesnt work, nothing returns.. if i run start:dev as usual it works great, but "listen" : "nest start --watch --config listener.json", doesnt let me consume the endpoints of the api. If i run the other app ( 8000 ) emiting the string, app 8001 receives the emit correctly, but cant use postman or any endpoint .

It would be nice if you paused for a moment before hitting Enter in the terminal. Without this, it is difficult to stop at the right moment and rewrite the code.

How to handle exceptions thrown in one service and to handle the same from the service sending the event?

[@guther]

I don't know, but... create microservice this way look like is creating monolitic, in the end all your code will be in the same Pod, in the same container. If some errors occurs will affect all project. I prefer split microservice in diferents pods or containers.

[@katthacar]

Hello, I have a question, if I have, 50 users concurrently connected to my server and 30 of them load at the same time a .csv file with thousands of lines, where each line of the file must be validated before persisting in the database . Since this task blocks the cycle of events, is there a solution with NestJS or should I definitely use another technology for these cases?

[@ScalableScripts]

You can use queues docs.nestjs.com/techniques/queues . You can save the files in a temporary directory then you can send a message to the queue to process them. There will be a job that runs every x time that will get the queue events, processes the files, then removes them. This is one of many solutions

[@nhatquang7637]

I have a question that is there any solution to start both the server and listener in one command ?

[@ScalableScripts]

I would use Docker check this other example for another app: kzbin.info/www/bejne/fnSZYpudqtF3abM

[@damaroro]

You can use concurrently library

[@bnd8371]

import { NestFactory } from '@nestjs/core'; import { Transport } from '@nestjs/microservices'; import { AppModule } from './app.module'; async function bootstrap() { const app = await NestFactory.create(AppModule); app.connectMicroservice({ transport: Transport.TCP, options: { port: 3001, }, }); await app.startAllMicroservices(); await app.listen(3001); } bootstrap();
