Hi Folks! If you are interested, I'm currently developing a new course - building a gRPC Microservice in Go which you can find here - tutorialedge.net/courses/go-grpc-services-course/ This covers everything from project setup and layout, testing, and best practices around things like versioning.

If I was to consume an api as a client, I assume I would just look at what the output of the api is (in api documentation e.g.), define my own chat.proto like I would define my own json model struct in rest, and then it just works the same way? And would the chat.Server be my place for dependency injections? If so, this seems so lightweight and convenient.

@Tutorialedge4 жыл бұрын
One approach I've seen used in production environments is to have a monorepo that contains all of your compiled files in every language that teams in your company develop in. You then follow appropriate versioning in order to ensure that any breaking changes are done under new versions and don't break existing applications using these compiled files. Let me know if this helps! I'm actually planning on doing a more comprehensive series in the near future!
@umeshsunnapu2 жыл бұрын
very helpful. just one edit compared to when this is recorded vs current releases of protoc, proto-gen-go-grpc etc. I believe executing protoc command, did not add package name in chat.pb.go and instead had it like ___. Change that to "chat"

Would we implement this Sayhello function in the same package chat in produciton, because it seems reasonable that we would implement it in other package so we "hide implementation" from client, this way client could just call the function without having to use RPC... correct me if i'm wrong

I'm following along and ran into some issues: using go v1.16 in VSCode with the go helpers installed. At 10:39 I'm being told that *Message is not defined. It's my understanding that the `package chat` declaration in both the chat.go and chat.pb.go meant that no import was required. Further, at 13:25 line 21 I'm being told RegisterChatServiceServer is not declared by the chat package. The package is definitely imported, as autocomplete suggested the method. Is there something happening due to differing versions of Go between the video here and what I'm using, or do I need to look for issues elsewhere?
@Csc5csc53 жыл бұрын
Figured out half of it - chat.proto requires a line: `option go_package = ".;chat";` to be included. Still stuck on server.go ln 21: passing &s into RegisterChatServiceServer, but I'm sure I'll figure it out.
@sreerampanigrahi2 жыл бұрын
@@Csc5csc5 Hey! I've found the fix and putting it here so that it helps someone in future. Basically we need to embed the field. i.e. Add this part in the chat.go file and it should work fine type Server struct { ChatServiceServer }
@nazarpysko2 жыл бұрын
Try compiling the proto file with this command too: protoc --go-grpc_out=./ chat.proto It generates another pb file and it contains all the functions shown on the video. There are few other changes that must be made. Search for my comment for more details.

@Tutorialedge8 ай бұрын
gRPC is typically built on-top of TCP and is one of the highest performance methods of transportation available due to the fact you are sending far smaller amounts of information (typically) than say JSON over HTTP. In terms of simplicity, I’d 100% agree with the statement that JSON over HTTP wins every day of the week. I’ve seen both sides of the coin and definitely lean more towards JSON over HTTP for all applications that don’t demand the absolute highest of performance.
