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

[@tonskreee6213]

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.

[@oyinlolaolasunkanmi]

the order service serves as the entry point into the application. Therefore you need to instantiate Rabbit MQ from there.

[@andyslack1167]

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)?

Hello, two questions: Why billing service doesn't have a port defined? Shouldn't we have a separate database for each service?

[@MenottiRicardo]

I wonder the same

[@theaungmyatmoe]

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

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?

[@jheremiaspulache6836]

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?

[@franccescomichaeljaimesagr7162]

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.

[@mguay]

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!

[@brucearmstrong5536]

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

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!

[@zackinfos5933]

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.

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.

Michael Guay When I see this tutorial I see something That caters to my direct needs... I hate the overly simple out of the box lessons where you can tell the person is just reading from the documentation and giving you examples that do not function in the same actual way that a production application is going to... they will give you some generic things ... but then just slap a ribbon on the process and call it a day... your giving so many real world examples... and ones that actually illustrate some of the things that the documentation miss or gloss over too quickly... like for instance it was giving me some issues with understanding how things were injected -> because yea its obviously easy enough to use say a mongoose injection.. but to go in and inject the rabbitmq / injecting the billing service... all these interconnected pieces -> and then the fact that were workingn with it all under docker -> and in a single easy to follow flow that you give ever piece it's due time in explaining what it is and how it works... The fact that your showing us how Env can be dynamically used.. is huge... Probably not to someone that knows how to do it already -> but ive never seen that in a nest lesson... they always leave me as prepared as i already was after reading the docs... this gives the bread and butter and then some... please keep making these types of videos my friend
