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 :).
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
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!
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 !
awesome bro, i was breaking my head trying to understand this, thanks for your service to mankind by uploading this video and the simple clear concise means of communication is solid gold.
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.
Incredible content. The way you explain and walk through concepts (and especially with the coding session) is top notch. And your excitement is contagious!
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
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!
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!
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.
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)
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?
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
Can you watch the NDC conf GraphQL, gRPC or REST video and explain how gRPC (a protocol) would be in a discussion in comparison to Rest or GraphQL? Shouldn't gRPC be more compared to HTTP1 or even HTTP2 alone? What difference does it make to compare to REST or GraphQL endpoints?
headjobs I can see gRPC being compared to REST and eventually graphQL because it addresses a problem those two (architectures?) have. Client libraries. Specially HTTP client libraries in case of REST. gRPC uses HTTP/2 a vehicle but it doesn’t matter what protocol it uses. It “hides” the complexity for us users to deal with client libraries. So theoretically if we were using gRPC. The protocol can upgrade to use HTTP/3 with QUIC and we will not have to touch a single line of code in our application. And all of a sudden we take advantage of the new transport protocol ! REST and GraphQL is built on HTTP (I think graphQL might be less sticky) but yeah with sticky protocols the client is “aware” of the transport protocol and the application is stuck with it. Changing the protocol is extremely hard. Thats why we are still struggling to upgrade to HTTP/2 from HTTP/1 .. millions of applications built (C#; C, VB, Python,) are still using HTTP1.1 client libraries.
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!
quite late but if someone can clarify, I couldn't understand when did he compiled the .proto file, is it not necessary? how does that code is working if he didn't compiled the .proto file. edit: is it because he used proto-loader??
What is the problem with OpenAPI codegen tools auto-generating client and server? Is the open source codegen libraries are not reliable? Google released Angular 1 and then the next version did not provide backward compatibility and now it is has reached end of life. Only thing with gPRC I see is the compression performance. Otherwise, it is just like Google competing with Facebook's GraphQL.
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?
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.
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.
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?
using L4 proxy with grpc wont load balance the requests equally it will load balance by tcp connection which each connection can have multiple requests so we can say L4 proxy will load balance the connection but not the requests not like what we expect with load balancing http1
Great video, helped a lot. I have a question though, how would I be able to access the outputs from my grpc services from my main program, since the callback isn't aware of my local variables and vice versa. Say I wanted to store a todo response as the client, to be used later down the line instead of printing it in the callback, how would I do that?
Hervé SV if you are planning to not use the response immediately you can store it on memory or on disk and retrieve it when you need it. Declare a global array in memory and push results in it. Or use sqlite
@@hnasr Wow, thanks for the quick reply! However, when I use a global variable to store the response, it always comes out as undefined whenever I try and access it outside of the callback function. Am I doing something wrong?
Why does client.readTodosStream(); print always the previous added TodoItem? Is it because the client is too fast? So if I also want to print my newly created TodoItem to be included with readTodosStream() what are the possible solutions to this? Starting to learn gRPC :)
May I ask ? does client need the schema like from the server to communicate or client does what's schema build on the server? In short does client can have both the same file protobuf? if you get confuse about my question let me know :). Bty the nice tutorial
Thanks for your tutorial . Very nice , I think gRPC uses for cimmunication between micro services on your servers . For example you have on micro service for uploading or downloading's files. Other micro services for using upload or download files , Call grpc services for uploading or downloading . Am I right ?
Pourdad Daneshmand correct! That is one use case it can be used for any communication between microservices uploading and downloading files is attractive because of the compression and binary format you get with gRPC.
@Hussein Nasser, great explanation ! My question to you is: What would you use to build a web app similar to Zoom in functionality, but more performant and flexible. WebSocket vs webRTC vs gRPC ?
Thanks for your great tutorials. I have a question and would be so grateful, if you can help. Is there anyway to decode binary data of body of a gRPC request without have the proto? I am capturing the requests made by an application using gRPC service. I cannot repeat the requests just like the app as the body of HTTP requests are in binary and I cannot understand and decode it. It would be great if you make a video on it. Thanks
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.
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?
Great video. I have a doubt. I think, Generally microservices are deployed on different servers. In that case how do we have a shared proto? otherwise we end up writing proto on both services which will be duplicate and maintaining will be hard.

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.

Great video.
I have a doubt.
I think, Generally microservices are deployed on different servers. In that case how do we have a shared proto? otherwise we end up writing proto on both services which will be duplicate and maintaining will be hard.
1. add a ci/cd pipeline step that adds the updated proto 2. use same repo two diff init commands for both server and client
