grpc-gateway VS rest

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.

Swaggest Rest can generate OpenAPI definitions from Go code, but it's not as comprehensive as Goa and does not support gRPC.

This is what I use: https://github.com/swaggest/rest

This has been the best implementation of the use case interactor I’ve seen and it outputs spec 3: https://github.com/swaggest/rest

Other times you might need a JSON REST API to generate OpenAPI docs code-first… for that I’m a fan of Swaggest REST. REST through clean arch.

For full code-first OpenAPI v3 REST, I’ve been using https://github.com/swaggest/rest and I like it.

For anything that needs OpenAPI docs, I’ve honestly found https://github.com/swaggest/rest pretty awesome. It’s basically just doc generation on top of Chi, but it does a lot of stuff right.

I used Echo for a lot of stuff (and it was easy to work with), but recently OpenAPI 3 has been a requirement, so I've switched to https://github.com/swaggest/rest

I've tried go-swagger comments to instrument existing code, but wasn't quite satisfied due to magical nature and error friendliness of those comments. So I decided to implement first-class OpenAPI generation on top of self-documenting action handlers: https://github.com/swaggest/rest/blob/master/_examples/basic/main.go. Schemas are generated from request and response structures using reflection and field tags.
