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.

In this video I want to explore gRPC, go through examples, pros and cons of gRPC.

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

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?

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 жыл бұрын

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.

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

@augmentos 4 жыл бұрын

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?

@hnasr 4 жыл бұрын

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.

@hervesv9529 4 жыл бұрын

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 4 жыл бұрын

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 4 жыл бұрын

@@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?
