go-grpc-middleware VS grpc-gateway

Hello, Those interviews are even crazy for internship. Anyway 1. Try to find a simple CRUD example online. You can check [this](https://tutorialedge.net/golang/go-grpc-beginners-tutorial/) 2. For logging you can check [go-grpc-middleware](https://github.com/grpc-ecosystem/go-grpc-middleware) 3. You can grpc-gateway in case they want some REST endpoints too 4. Use base62 to encode your url. So at least 2 columns in your table **shortenedUrl** and **url** 5. For such a project no need to use an ORM ( it's not advised anyway ). Implement 2 functions, one to insert into the db and the other one to read from the db. Remember to use transaction though 5. For unit tests go with the standard library and mock the 2 functions ( erroneous and valid cases )

Supported middlewares by gRPC framework.

I do some basic validation at the server layer using a GRPC interceptor.

Example auth middleware: https://github.com/grpc-ecosystem/go-grpc-middleware/blob/master/auth/examples_test.go

And initialize our gRPC service, here i used gRPC Middleware repository for unary interceptors:

I found this is very good gRPC Middleware repository, but we easy can create our own, for example logger interceptor:

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.
