- Nodejs Microservice tutorial, Through this video we will learn how to kick start with Nodejs Microservices with the help of a quick practical example. For demonstration purpose, I have picked a NodeJS monolithic application and split into microservices and showing how it is serving the frontend exactly same way like monolithic with added some flexibility.
It is highly recommended to code along with me if you are comfortable so you can move your progress step by step.
You can find the source code from the link below to compare your code.

My little contribution if help you to grow I will be very happy.
Thank you.

Great tutorial! I feel like there should be a shared library between the microservices to avoid typing class models as literal objects.
Not only this other contents are also really amazing in this channel
keep it up keep going .
part1 is fine and easily to follow, part2 clean code is little bit hard to follow, will review again after all videos are watched. Thanks for the refactor videos step by step.
A lot to learn from this video.
Thanks very much , I wish I land my first job to pay for your channel
that was a great series thank you
Hi Jay, You storing orders and whislist in the user object, In the future, what if the product name is updated for a particular product id, how you can handle this situation. Could you please explain those scenarios? it would be great. Till now, your concepts are clear. Thanks
Great video. I understand that every microservice should have its own database isolated from another but how could we avoid hardcoding the properties in each db?
I believe we can do everything related to DB through migration. Decoupling and use of dynamic properties we will learn in coming episodes for sure. End of the day every microservice will have its own properties and responsible data only other than redundant one. Please refer to episode 5 for understand better this concept.
Cheers!
Awesome work thanks a lot
Thank you for great turtorial. I have a question that: in 5:09, why didn't you delete the populate('withlist') when you have deleted the product model
Yes I could have done that. I was more focused on the microservice representation rather focused on business logic.
Cheers!
Great video,looking for new video.
Please do a real time projext on kafka/rabbitmq with nodejs.
thank you so much. you are amazing
very very Good and Usefull
great, you're master. Thank you
Great tutorial! what application did you use for the diagram illustration (white board)?
Thank you for appreciation!

Enjoy!
Could you please provide a video that explains the monolithic part step by step? I don't understand it.
Watch NodeJS Online Food Order series to understand Monolithic architecture.

Another amazing video! By the way, how are you populating objects that are not Mongoose Schema.Types.ObjectId?
Apologies for late response!
For individual schema it's not mandatory to have an ObjectId to populate data you can use search query to populate. In the most use cases we are using ObjectId references for relations or embedded schema for achieve the goal. But due to limitation of embedded schema it is suggested to keep schemas small and separated but always use reference ObjectId to establish relations. For populate related the data make sure at least you have correct reference id to use it's query parameters to populate deeper items.
how to fix "undefined
TypeError: Cannot read properties of undefined (reading 'split')"
Thanks!
Great Video man, tank you :D
my only question is, can we do the same thing using functions instead of classes?
Yes you can do that. You can follow this playlist where we have use functional programing for everything. ruclips.net/p/PLaLqLOj2bk9aaZZYoH7tMDj5obE7os45_
Cheers!
Thank you so much Jay, you are awesome. I am learning so many things.
Thank you so much🙏🙏🙏🙏🙏🙏🙏
Thanks!
Thank you bro
you're coding style id too different is this old style or new one?
There are no old vs new. You can adapt the way to get it done. if you wish to learn more about the current coding standard follow our Kafka Microservice series.
@@codewithjay thank you so much for your replay I'm a backend node.js developer i want get more knowledge in backend so is these series enough?
tnx man
is it possible to make the vscode font bigger? it is too small for me :'(
Certainly, I will make it lill bigger for coming episodes. Stay tuned to my channel for more interesting topics.
Can you share git do download the cde

hello sur first thank you for your wonderful video but get an error for mongodb connection like listed error below sow would you help me Error ============
MongooseError: The `uri` parameter to `openUri()` must be a string, got "undefined". Make sure the first parameter to `mongoose.connect()` or `mongoose.createConnection()` is a string.
Same here please try to console log the DB URL you are providing correctly or not?
You need to add npm run dev line which is mentioned in the video. Then close the exisiting terminal and run the command 'npm run dev'
Can you send me the fontend code of this project? thanks you

Hi, help me solve problem!
PS G:\Tutorial\Grocery_Online_Shopping_App\online_shopping_monolithic> npm run dev
> shopping_app_monolithic@1.0.0 dev
> NODE_ENV=dev nodemon src/index.js
'NODE_ENV' is not recognized as an internal or external command, operable program or batch file.
Error ============
MongooseError: The `uri` parameter to `openUri()` must be a string, got "undefined". Make sure the first parameter to `mongoose.connect()` or `mongoose.createConnection()` is a string.
You need to use .env file for DB_URI. It is clear that mongodb connection is empty. Kindly check the source code and you will get the information there.
You need to add npm run dev line which is mentioned in the video. Then close the exisiting terminal and run the command 'npm run dev'

at NativeConnection.Connection.openUri
Please check your local mongodb is running correctly or not. And make sure in the env you need to pass the mongodb url.
