go-grpc-middleware VS protoc-gen-gorm

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:

2: You can use gorm to save time and can also use protobuf plugin to make your life easier. I like https://github.com/complex64/protoc-gen-gorm it does not support relations yet but I guess you only need one table. ORM is not recommended but working with protobuffers you can save a lot of time with auto generation. if not ORM, u/jloking post makes more sense.
