examples VS grpc-gateway

Probably you should use something like errgroup, take a look at gin multiple servers example

You can just read the documentation https://gin-gonic.com/docs/ and work through the examples https://github.com/gin-gonic/examples there quite good. Happy coding

There's an example for gin https://github.com/gin-gonic/examples/tree/master/grpc

Since you're working with DRF, you're probably interested in REST web apps. The best way to practice Go then would also be to learn to use it to build REST web apps. Most people will build with the standard [http](https://pkg.go.dev/net/http/) library as it's comprehensive enough though some time like to use the [Gin Web Framework](https://gin-gonic.com/docs/). The standard http library fills my needs to do simple REST API calls so I use that.

it lacks flexibility but i really enjoy grpc-gateway for 99% of my work

gRPC Gateway is a protoc plugin that reads gRPC service definitions and generates a reverse proxy server that translates a RESTful JSON API into gRPC.

I don't have any example that's public atm, but the guide in grpc-gateway is pretty clear/can be followed step by step.

To integrate with Fiber, I used the Fiber Adaptor (also pretty straightforward): https://docs.gofiber.io/api/middleware/adaptor

I wonder if they would be happy with something like this: https://github.com/grpc-ecosystem/grpc-gateway

Protobuf is used is massively scaled services like firebase. But you'll still see JSON in streamed realtime services like AWS Kinesis. Hopefully google had a return on investment for creating and using this protocol, but it's not hard to prove that it's far from essential. Out of apparent convenience I use grpc-gateway so I can expose both Protobuf and JSON, but honestly I wouldn't do it again

GRPC is an alternative to rest, rest and GRPC both use the http protocol. But you won’t be able to use fetch to call a GRPC endpoint, you should look into setting up a GRPC proxy within the application(hopping you have access to the source code) grpc-gateway. If you don’t have access you’ll have to create a new container that proxies the calls

(There is an option called google.api.http, that lets you set up a URL that can be used to make HTTP/1 REST requests, which get translated to gRPC calls if you're using grpc-gateway as a proxy in front of your service. That has nothing to do with the requests that are made by gRPC clients and servers themselves.)

Have you looked at https://github.com/grpc-ecosystem/grpc-gateway ?

protoc-gen-grpc-gateway — plugin for creating a gRPC REST API gateway. It allows gRPC endpoints as REST API endpoints and performs the translation from JSON to proto. Basically, you define a gRPC service with some custom annotations and it makes those gRPC methods accessible via REST using JSON requests.
