RabbitMQ - RPC with NodeJs (request-reply pattern)

We're gonna implement the RPC (remote procedure call) pattern in Nodejs, using 2 different services: RPC_Client and RPC_Server, in order to understand the concepts of request-reply in RabbitMQ while creating a real case scenario.

This is YouTube's hidden treasure that's just waiting to be found!

In-depth RabbitMQ content is very scarce on YouTube, and message brokers in general, and you did a signifacnt job on explaining it.
Impressive work and effort, bro! Can't wait for this to blow up.

I couldnt find one proper video explaining RPC with node... Finally found this

Thank you for this. Cheers from norway!

Thank you for this very good and professional course that is available for free

I can see your channel growing quickly. You're giving the people what they need 👍💪

[LawZist]

Subscribed :), one thing you can add is to remove the event listener from once the response came back

such nice man you are, such nice tutorial

[ShubhamSharma]

Thanks for the tutorial you saved my a$$

[hassanmhassan]

Amazing bro, thank you for sharing such precious knowledge

Your content is truly invaluable! If you have the time, would it be possible for you to create a video or series on building a mini ecommerce or social media backed application using multiple services, such as authentication, user management, order management, product management, and cart management, while adhering to best practices? This would greatly benefit learners looking to expand their knowledge in this area.☺

Great video man! I would want to know how you did this magic on 19:31? (check available props of object) - which is hotkey for that? I'm looking forward new videos about RabbitMQ ! Thanks

[SalmaElMorshedy]

Thank you for the Tutorial, may I ask why we created two channels each for a producer and a consumer, Can't we connect both producer and consumer to a single channel on the client side and similarly connect producer consumer to only one channel on server side, so in total we have two channels on RabbitMQ?

That was the one part that was missing in my life 😅

How to manage rollback mechanism.? for example if my 1st service have update some data after update completed based on 2nd service add some data, if 2nd service failed i want to rollback 1st service execution, how i can achive multiple micro-service in nodejs.?

[bikramgyawali]

this is really awesome content about RabbitMQ ever seen . I got good knowledge from this and your other video about rabbitmq, Can you provide me the source code link ? Thankyou again

[Nikunjtechhive]

can i use same request-replay-pattern with kafka.? can you please create video about request-replay-patter with kafka in nodejs with typescript.?

[hoangofficial]

hi, what if a service acts as both a client and server?
