gRPC Crash Course - Modes, Examples, Pros & Cons and more
gRPC (gRPC Remote Procedure Calls) is an open source remote procedure call (RPC) system initially developed at Google in 2015. It uses HTTP/2 for transport, Protocol Buffers as the message format.

gRPC Pros and Cons
Pros
- Fast two/uni and request
- Unform
- One library to rule them all
- Progress feedback( long synchronous requests) drop pluggable wait...)
- cancel request
- All benefits of H2 and Protobuff
Cons
- schema based (not everyone wants schema)
- Thick client - limited languages - Proxies still don’t understand it
- Still young
- Error handling
- No native browser support
- Timeouts, circuit breaker just like any RPC (pub/sub rules in this case)
Can you create your own protocol?

"it's like a first date, take it slow, take it slow guys" 😂 This channel is gold
I really like you giving the "Why" question at the start when always explaining something. Whenever I have the very "Why" question, I look for the answer in your channel. Thanks very much for your dedication
Your youtube channel is a Gold mine for someone who wants to explore the backend world. Every time I start to learn something new, I first check whether you have already explained it or not. Thank you so much for uploading such High-Quality content for free. Will look forward to amazing content in the near future also :).
I turn my ad-blocker off when watching your videos:) Thank you for all the useful videos!

Making a crash course is already a very tedious process. But you make everything so simple. "Simple ain't easy". Being an Android dev I like to watch your videos. Thank You
Learn the fundamentals of the backend, scaling and load balancing with my Introduction to NGINX udemy course nginx.husseinnasser.com
I've been at this life for 20 years now (33atm), hands down the best introduction i've had to a new (to me) tool/underlying-protocol. Starting now I will always check your channel first when adopting new tech. Thank You
Loved the introduction, straight to the point, no nonsense like saying "Hi guysssss, welcome back to another episode of... here in this..." omg thanks. Also no annoying music and a slowed-down voice when throwing information away, to not overload the receiver. Pure gold!
From watching your video to pass interviews to watching them for Job application.. I grew up
I will always remember "today, the 4th of December 2023" when I discovered your channel. Amazing Amazing teaching style and content. Despite the humour and jokes, the content is seriously well thought out and structured !
Incredible content. The way you explain and walk through concepts (and especially with the coding session) is top notch. And your excitement is contagious!
Awesome content. Thanks for this. You teach, as if you are talking to a friend. :)
Clicked this video expecting some monotone broken english explaining this way too simply with a bad microphone. Reallly appreciate the candor in your speak, it keeps the brain focused and that you didn't needlesly drone on on metaphors. Subbed!

loool, this is the most racist and funny comment I've seen this week 😂
Very informative and clear introduction of gRPC! I'm a devOps guy, understanding gRPC basics will help me build efficient infrastructures to support the microservices. This is a very good introduction for me to dive into gRPC.
This channel is awesome, what a gem.
Very clear explanations. Use of simple, understandable language also appreciated. Also, happy and excited manner keeps my attention. Genuinely didn't realise this video was over an hour long, flew by. Also, really liked how you zoomed in on the code. Really good feature. I was following along with this video only on half on my screen, so didn't need to strain my eyes. Thank you!

Thank you bro hehe just as crazy as i am , behind every single word i can feel the SUPER PROFESSIONALISM hahahahahahahahahahahahahahah Keep it UP and never forget the GOLDEN RULE
crazy way you talk keeps my attention . love it 🙏
Thanks a ton, please continue making such videos.
Awesome hour of information.
"Take the whole array and shove it down the client's throat" 😂😂 I wish I could like the video twice
Can I subscribe for a second time, just to say thank you for your good work? Kudos Hussein Nasser
Good thing they open-sourced it. People interested in writing libraries can contribute to the gRPC code-base instead of writing their own library from scratch!
best video explanation for gRPC so far ! excellent job @Hussein Nasser
Hussein, absolutely love your video! Had fun and learnt stuff. Thanks!
Thank u Hussein Nasser to make this complicated thing real easy .... saved a lot of time
Excellent. You are a born teacher. Enjoyed it a lot. Keep them coming.
really like the way you make it, Focus in why we need this, most people don't care about the reason, but i think this is the most importance thing
Such content much respect. Thank you very much for sharing your wonderful knowledge with us.

This channel is the definition of "goldmine"
Watched thanks Todo take notes It seems that the single biggest advantage is that it abstracts away the underlying protocol like http2, and uses protobuff binary format Has support for server streaming (client makes a call and registers a callback on that call. The server then keeps streaming back objects and that triggers the client callback to handle the object stream)
As someone who builds SaaS at scale, I appreciate your take on industry nonsense and reasoning
Love the way you tell and teach your videos are really informative thanks 👍

You make so many topics easy to understand and the videos are quite entertaining. Thanks for making my life easy Hussein!

Hi Hussein, great video! Just 1 small thing: this line "if (!response.items)" at 55:46 should be "if (response.items)", right?
Super cool video. Enjoyed it a lot! On the topic of browsers lack of gRPC - I would speculate that the main idea is to use gRPC in browsers via web assemlies.

Hi Hussein, New viewer here, protobuf and grpc brought here, awesome explanation and like way you explain. Giving as much as someone can in a light mood. Awesome. Love your content. One request, can you explain with example WebRTC? Thanks, Ratnadeep

Thanks Ratnadeep for your wonderful message and welcome to the channel 😊 WebRTC has been requested alot and it is on my list. It is a very complex topic since it has so much low level networking that the audience must understand. So its gonna take me a while but its coming :) thanks again
We should have "like levels"! This would be a huge like :-D
This reminds me of libp2p: A library for peer-to-peer communication that implements all known open source protocols (Bluetooth, WebRTC, TCP, UDP etc) so all you have to do is use the libp2p api as an abstraction layer on top of the implementations. You can even plug in your own custom protocol and extend libp2p's capabilities. Can you do that with gRPC?
Great video helped a lot.. Thank you :)

Thanks for the video! What do you think about developing gRPC service between using Node.JS and Golang? I've seen a lot of job posts with gRPC also mentions Go instead of Node.JS. Does Golang have a better tooling or there are something else that makes using Golang with gRPC is a better choice?
@hnasr

I don't have a favorite to be honest it really depends on your use cases for the language of choice but the goal of gRPC is so that the language you use to build your backend doesn't matter.
Some other downsides of gRPC and Protobuf to add to your list: gRPC weaknesses - Protobuf is not human-readable. This can make debugging and payload analysis more difficult than they would be with a human-readable format. - HTTP/2 still has some latency issues due to headers being used in each exchange. - Although apps can use the code libraries to access gRPC, web browsers don’t support it directly. This means you must use a proxy such as gRPC Web to support gRPC in browsers.
You have excellent eloquence and you understand what people think about ( ^__^ he reminds me in JOKER )
Super video! I applauded for ₹40.00 👏
Hi Hussein, Thanks for the awesome video. I am new to gRPC, it is said in the video that the reason gRPC is invented is because there is only one library for all, but then I think every language have their own gRPC library too? so it is no better than REST in this case? Please correct me if I am wrong. Just confused about it. Thank you

I am also new to gRPC. But aren't the libraries in other languages lightweight libs as gRPC is the one that handles all the heavylifting? Hopefully it helps.
Awesome content!
Thank you Hussein. A quick question: How can I manage GRPC in a micro-service environment where each service has a least 2 instances?
you are amazing teacher bro make more videos please i love ur content
Hello Hussein, what is that extension you use to see the nested object when you hovered over the "call" input to see what was sent from the server. The object called ServerUnaryCall. Thanks a lot!
Simply awesome !!!
Thanks for the video. !!!
Great Content 👏👏
Any thoughts on updating this video now that we have gRPC-web?
You are great. Thank you!
I never knew King Julian changed careers to teaching coding
Do you have a tutorial for this in PHP Laravel? Btw great crash course . I learned more about gRPC because you presented it with a clear explanation.

Hi, can you make a video with spring boot gradle grpc microservice and talk with Smartphone app(client as rest api)
does this library platform independent or work on the baremetal platform ( environment without OS /kernal)
Hi Hussein, u r doing great job Do we need her to run proto file as u did in protobuf tutorial? I ran in problem that my req are getting in server, request is empty object. How to solve this?
Proxies... I give you that one
protoLoader wasnt picking up the path to the .proto file for me, till I switched to using nodejs "path" module

This happens sometimes if your proto file is in a sub folder. Thanks for mentioning that hopefully it helps others who ran into the same problem
Thank you so much Hussein. I have one doubt though sorry if that is very basic, i am new to this grpc concepts. Recently i bought a VPS server where i hosted my two wordpress sites. I created some REST API calls through plugins from one site to another using PHP. When i do request a REST call, the network tab under chrome shows h2 as protocol. So REST API works with http/2? or am i missing something?
@hnasr

That means your PHP backend and your frontend support HTTP/2 . Which is a good thing REST API works with any underlying HTTP protocol its transparent.
top notch
Hahaha even i was looking around what hello world, hello anybody there kind off hahaha
