Wow. This dude is just giving away thousands of dollars worth education for free. Salute to you sir. You are helping many. I wish all the success in your career.
I am watching you videos and this video specifically it is really great to have such content. Because there is almost no one on the internet who is helping with Microservices with NestJS. Thank you for the content from all of us. I am sure many people will take help from this video.
Hello Michael, I would like to thank you very much for this content, it is very rich in detail and helped me a lot to understand a little more about microservices and also monorepo with NestJS. You've gained another subscriber. Congratulations on a job well done.
Wow, this was the missing piece for me to start using microservices pattern. The puzzle is almost completed (just waiting for deployment part) :) Thank you, Sir.
Excellent tutorial! This works out-of-the-box from your Repo on a Mac with an Intel Processor, as expected, but I've been trying to update the Images for the Apple M1 ARM64 Arch. Have you tried this as well and, if so, would you mind sharing updated docker-compose / Dockerfile(s)?
The way you explained is really awesome and helpfull. I have some confusions : Why do we need to create two JwtAuthGuard and how you are deciding where to use JwtAuthGuard and flow of its execution?
Awesome content! Really well explained and it's insane how every time I watch some NestJS content I learn a new way of doing the same thing. This bad boy is actually quite flexible for a framework. Do you plan on doing a video where you e2e test an application? One of your videos on unit testing really helped me on work 🙏🏽
Thank you sir for everything you're doing for us, but could you please tell me why you have followed the one shared db approach for all microservices you have implemented? The one db per each microservice could be more suitable for microservices architecture.
Nice video and great content , Can you make a enterprise level application using NestJS with micro-service architecture in which you cover e2e testing , caching, queue management system etc. which required to make production level application using micro-services architecture.
Wonderful video mate! Helped a lot to understand the system and I would like to give a feedback. Can you make commits as you make progress? For example we have "docker", "microservices" and "billing app" chapters on youtube, wouldn't be good if you make commits for each youtube chapter?
Hi Michael, this is really nice, keep it up and thank you. I was wondering instead of building authentication service from scratch is it possible to integrate keycloak in your setup as well as api gateways like apisix? If you can create a video that incorporates the two, that would be great. Otherwise thank you for such wonderful and educative videos.
For those who's having these problems: 1. Python not found when running docker-compose (and you tried npm config set yet failed, nogde-gyp configure yet failed): Try replacing bcrypt with bcryptjs 2. Error when connecting to database (if you're using Apple Silicon): Try changing the mongo image to: mongo:4.4.14. And if that doesn't work, try add these envs: - to your secondary and arbiter services on your docker-compose.yml: MONGODB_INITIAL_PRIMARY_ROOT_USERNAME=root - to your mongodb-primary: MONGO_INITDB_ROOT_USERNAME=root replace the MONGODB_ROOT_PASSWORD=password123 with MONGO_INITDB_ROOT_PASSWORD=password123 Hope this helps
really good tutorial, thank you for creating this video bay the way, sometimes when creating an app we also need the second auth for admin, regarding with auth guard, what is the best practice you advise for this case?
Thanks for the awesome video Michael. I was wondering how it is possible to connect to 2 databases from one of the microservice and second microservice connects to only second database and both are responsible for read/write operations in that database. I know there can be microservice communication used but if we wan to avoid the delay.
That was a really good content! One question, if my monorepos had different dependencies, do I necessarily have to create a package.json file in each microservice and have the node_modules folder in each microservice? Could I have common dependencies and also specific dependencies at the same time? Sorry for the questions. I hope you can understand my questions. My native language is spanish 😅. Greetings from Peru.
This is a great question. You could make the individual approach with each service having its own package.json/node_modules, or you have a shared one like in my video. I am not sure if it is possible to have shared/individual at the same time but I would be curious to learn!
Great tutorial, thanks. Why using MessagePattern and switch to rpc? In Auth microservice the rmq auth queue is connected, isn't that mean that we can use EventPattern in auth controller?
Thanks! Tutorial straight to the point. In my case I came across the problem, have you dealt with this error? "There is no matching message handler defined in the remote service."
@Michael, thank you for the great tutorial. I have a quick question regarding deployment. You see... the Billing service doesn't listen to any port. With this setup, how do I go about health-checking the service container within AWS ECS? The easiest option that I came to my mind is making it hybrid app just like the Auth service to be able to make a HTTP call to the container via the port. What else option do I have?
Nice video Michael but I suggest to use any diagram for more simplification before starting that will make it very easy and will get new ideas from comments sure
Great content. Michael Guay, on the auth service, why is it that instead of validation I do get always a 401 Unauthorized? Is there a way of working around this?
Awesome Stuff, I realized that sevices connect to same db, and u have userModule a sub module for parent Auth As Auth is dependent on user and Splitting it into 2 micro services get this tutorial complex Question: is it Good to connect API with mongoDB directly through mongoose for same user collection "mongoose.forfeature({ schema: user, name : user })" instead of, exporting userservice , repository or userSchema and importing the user module in auth module ? Is this a good practice ? adding "mongoose.forfeature({ schema: user, name : user })" for 2 different modules that dependent on same collection I can see some benifits like easier to switch between monolithic / microservices more cleaner and not to much nested file structure Not expert at nest or mongodb
Hello! First of all- thanks for such a gift without christmas! Highly liked this course and want to discuss interesting moment, concerning docker-compose. For example, we got a string - /usr/src/app/node_modules in our orders container. But it makes us involved in a problem - each time when we install new deps - we have to restart with docker-compose up --build -V. Which is unnecessary, if we get rid of this string. Do i understand it right, that there are some things, that i dont understand and this is not a mistake? Thanks in advice :3
Hi Michael, May I know why both on Auth and Billing service you define the app.connectMicroservice functionality but in Order service you didn't define the connectMicroservice instead you call the RmqModule.register which calls the ClientsModule.register, is there a rule for this one? because I thought when we want to define our service as microservice we need to call the connectMicroservice for each services? sorry im new to microservice and nestJS.
well explained, learned a lot, liked the way you make use of the common library for rmq and mongo I'm having a bit of trouble connecting to my mongodb when using compass, can I simply connect on localhost:27017 with root:password123 ? or is it different with the way it's set up in your video?
Great content. Thank you. I have a small doubt regarding registering the RmqModule. You have registered it in order module import. However If I want to use it in another module should I register again? Or is there anyway I can register it to a common module and import that module everywhere else in my code. For example emailQueue is something that I might require in multiple modules (order, billing and auth). Can you suggest me a generic way to register EMAIL_SERVICE (emailQueue) in all the modules please?
May I ask a question Monorepos can't be deployed seperately, so why is this still considered as microservices? It's more monolithic app structure I guess Thanks!
Hi Michael, I'm a newbie with NestJS and RabbitMQ, this series is really nice and helps me a lot to understand, thank you! But I got the error when I practiced, I followed the steps that you did and also downloaded your case to references, but I got these errors while I emitted the message. Do you know what's happened? Error: WARN [Server] An unsupported event was received. It has been acknowledged, so it will not be re-delivered. Pattern: notifications
Hi Michael. Thanks a lot for such a great tuto. i was struggling with architecture and evething looks more clear now . I previously follow your tuto about gcloud kubernettes deploiement , but that was for mono repo . Please could you show how to deploy this architecture ? how the dockerfile and deploiement.yml should look like , and witch image(s) is sent to docker hub. Thanks in advance.
Why I can't connect mongodb replicaset in my Macbook M1. Error throwing like this [Nest] 69 - 10/24/2023, 10:35:24 AM ERROR [MongooseModule] Unable to connect to the database. Retrying (1)...
Thank you for great tutorial. But I'm not idea write unit testing for controller and services. I try to write a. unit test but not work because it many dependencies. Please help or guide how write unit test.
@Michael Guay hey, do you have any course about nestjs with microservices from scratch? or another option, what is the best approach to learn nest js and microservices? i know express, and i know the concept of microservices, but i did not understand what is nestjs and nestjs microservices . thanks
How would I go about enabling HMR for the individual microservices? I am able to do it for regular NestJS app setup, but with this shared libraries approach, I am not able to figure it out unfortunately.
Very good stuff indeed! Anyone got an idea of how the MongoDB connection string will look like if I try to connect to the running db instances using Compass?
Great tutorial. Thanks, Michael. For those who have a problem related to MongoDB connection, try below string; MONGO_URI=mongodb://root:password123@localhost:27017/?authMechanism=DEFAULT&directConnection=true
Hi, at 1:11:05 in ordering apps auth section, I don't understood why are you inject(AUTH_SERVICE) constante which is a string value as injector for clientProxy. How works this and in what way does this constant refer to this service ?
How does my application consume multiple queues. I saw an approach someone suggested on stackoverflow where you repeat the "app.connectMicroservice" for each queues, is there a cleaner approach ?

Thank you, Sir.
Thank you so much for the great tutorial!
Just a heads up for anyone using Macbook M1 with the ARM64 chip, Bitnami doesn't support it yet.
Yeah ;(
This tutorial makes microservice implementation looks so simple. Thanks coder!
This is awesome, man. Has been very helpful to me
It was an excellent explanation. Ton of things, we can learn. Just waiting for deployment part
Excellent tutorial! This works out-of-the-box from your Repo on a Mac with an Intel Processor, as expected, but I've been trying to update the Images for the Apple M1 ARM64 Arch. Have you tried this as well and, if so, would you mind sharing updated docker-compose / Dockerfile(s)?
Thanks man, it's really comprehensive. I learnt a lot from it
Awesome! Thanks for the great content, waiting for the deployment part!! ♥ Thx Bro.
The way you explained is really awesome and helpfull. I have some confusions : Why do we need to create two JwtAuthGuard and how you are deciding where to use JwtAuthGuard and flow of its execution?
Best nestjs channel out there.
Hey Michael, thanks for the tutorial, super educative! Do you plan to do a tutorial for authorization in NestJS?
Thanks! I have a video on this, check out my channel.
Awesome quality content. No BS.
litterlay a gold mine . nothing else to say 😘😘
Every one of your video helps me so much, thanks for doing this!
Such an amazing video. Really helped me learn and build my own custom project. Much Thanks. Looking forward for more nestjs content
Awesome content! Really well explained and it's insane how every time I watch some NestJS content I learn a new way of doing the same thing. This bad boy is actually quite flexible for a framework.

Really Appreciated , thanks for this great tuts. helps a lot.
You're the best. waiting for the deployment part
exactly 👍
Awesome! Looking foward to the deployment video!
Very cool 👍 graphql federation with microservices maybe in future ?
I got issues with MongooseModule, it says it can’t connect to mongodb-primary 😢
You are very good at teaching. Keep it up.
Nice video and great content , Can you make a enterprise level application using NestJS with micro-service architecture in which you cover e2e testing , caching, queue management system etc. which required to make production level application using micro-services architecture.

Minute 5:46, I am loving this tutorial, thanks!
Hi Michael, this is really nice, keep it up and thank you.
I was wondering instead of building authentication service from scratch is it possible to integrate keycloak in your setup as well as api gateways like apisix? If you can create a video that incorporates the two, that would be great. Otherwise thank you for such wonderful and educative videos.
For those who's having these problems:
1. Python not found when running docker-compose (and you tried npm config set yet failed, nogde-gyp configure yet failed):
Try replacing bcrypt with bcryptjs
2. Error when connecting to database (if you're using Apple Silicon):
Try changing the mongo image to: mongo:4.4.14. And if that doesn't work, try add these envs:
- to your secondary and arbiter services on your docker-compose.yml: MONGODB_INITIAL_PRIMARY_ROOT_USERNAME=root
- to your mongodb-primary:
MONGO_INITDB_ROOT_USERNAME=root
replace the MONGODB_ROOT_PASSWORD=password123 with MONGO_INITDB_ROOT_PASSWORD=password123
Hope this helps
Thank you!

hey, you have dropped this ... 👑
Really nice, were you able to connect into mongo atlas? I can't and it would be great to see data into database
Very helpful tutorial. Thank you so much.
absolute gold, thank you man

Great content. Michael Guay, on the auth service, why is it that instead of validation I do get always a 401 Unauthorized? Is there a way of working around this?
Hi! Thanks for the great tutorial... Is it possible to specify queue while emitting the event?
Awesome Stuff,
I realized that sevices connect to same db,
and u have userModule a sub module for parent Auth
As Auth is dependent on user
and Splitting it into 2 micro services get this tutorial complex
Question:
is it Good to connect API with mongoDB directly through mongoose for same user collection "mongoose.forfeature({ schema: user, name : user })"
instead of, exporting userservice , repository or userSchema and importing the user module in auth module ?
Is this a good practice ?
adding "mongoose.forfeature({ schema: user, name : user })" for 2 different modules that dependent on same collection
I can see some benifits like easier to switch between monolithic / microservices
more cleaner and not to much nested file structure
Not expert at nest or mongodb
Hello, two questions:
Why billing service doesn't have a port defined?
Shouldn't we have a separate database for each service?
I wonder the same
you don't need to define port in billing app because the app is not listen on the http or tcp. It''s listening to the Rmq
Hello! First of all- thanks for such a gift without christmas!
Highly liked this course and want to discuss interesting moment, concerning docker-compose.

Which is unnecessary, if we get rid of this string.
Do i understand it right, that there are some things, that i dont understand and this is not a mistake?
Thanks in advice :3
and envFilePath: './apps/orders/.env',
also is redundant here and may be omitted
Hi Michael,
May I know why both on Auth and Billing service you define the app.connectMicroservice functionality but in Order service you didn't define the connectMicroservice instead you call the RmqModule.register which calls the ClientsModule.register, is there a rule for this one? because I thought when we want to define our service as microservice we need to call the connectMicroservice for each services? sorry im new to microservice and nestJS.
the order service serves as the entry point into the application. Therefore you need to instantiate Rabbit MQ from there.
thanks so much for this video, i love it

It's very great tutorial for microservice senior. Anyway, could you guide or explain us how do we manage the API Versioning for both Route & Codebase?
Good idea.
