Looks like the corporate world is snatching up my courses! Don't worry, I'll whip up a fresh NodeJS course I have already in my pipeline. You can expect by end of this year.
i am on your discord and also in some video comment section saw a bit confused how to utilize your playlist like which order one should follow for beginners who are getting into backend. please make a video, that explain how to utilize your playlist in the systematic order like which playlist follow first then which next and so on. It would be really helpful
Sure! I will do that very soon. I am working on codewithjay.com where I will provide the career road map based on your skills and level so you can smoothly kick start learning for free.
Hey Jay, I have a doubt, in the scenarios where kafka queue is consumed slower than the messages being pushed, in an async message broker events flow when the pdts quantity becomes zero we might have to trigger failed orders or do you reduce pdt qty at the synchronous step (at cart directly)? or would you keep extra inventory? like how would we handle that scenario other than refund and failed transaction?? I welcome other peoples opinion too.
Hey Thank you for writing. This use case can be handled many ways based on your infrastructure. If you are using Kafka then make sure you have multiple instance of Consumers that if one is failed to consume other can use the fallback. But mostly kafka is realtime and it will not delay to consume or push messages. Another edgecase you implement pre-deduct stock while add to cart and if order is not placed correctly then revert the stock quantity. But this is more often fall into trap when customer is keeping the items in the cart for long time. Then the product stock will occupied unnecessarily. The last use case you verify the cart items stock when user visit the cart page by sync call to make sure we have enough quantity. In our case we are firing events from inventory service to cart/order service to ensure always notify about the product stocks left. example: only 3 left order now? :D I hope you got the idea. Cheers!
Hi Jay, looking forward to the next episode.
I wanna ask, why zookeeper and not KRaft?
Hey Thank you for writing. I have already explain what is KRaft mode in Kafka why it's needed in the implementation episode.
Cheers!
Hi Jay, can you make an alternative course for the NodeJS course as the previous one was bought by a company and you couldn't release that?

@@codewithjay And would you please try to not sell that one to a company. It would be generous of you.🙂
Sure! This one I will not sell it and will be dedicated you people only.
Cheers!

Thanks a lot 😍
Your support means a lot, thank you so much!
when this one is going to be completed?
One more episode with implementation part is on the way I am working on editing mostly Monday evening will release it. Then we will be quite close.
