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?
- Spotify example with Hermes

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?

@hnasr 4 года назад

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

@anz111 3 года назад

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 3 года назад

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.

@Bargains20xx 4 года назад

wow man, this is awesome

@mostinho7 Год назад

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)

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

To support video/audio and I get to pick between the three I would pick webRTC for audio/video and with websockets as metadata

@hervesv9529 3 года назад

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?

@hnasr 3 года назад

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

@hervesv9529 3 года назад

@@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?

@__________________________4584 3 года назад

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 3 года назад

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.

@isaacjohnwahing9118 3 года назад

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 :)

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

@diaryofsuman 2 года назад

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.

@samferrer 2 года назад

Nice presentation... as always ... but the cons could be constructive... for instance forcing a schema establishes a protocol across architectures, projects, organisations and so on. And once it is established test automation would be easier and solid
