README

grpcdiff

Tools to see different betweenr two different GRPC implementation with same interface

How to install?

If you have go in your environment you can use

go install github.com/egon12/grpcdiff/cmd/grpcdiff

How to use it?

First you need a request in JSON format that will be converted into GRPC Request (protobuf to be exactly). And seperate it by line

For examples:

{}
{"content":"hello"}
{"content":"hello_there"}

and you can save it as requests.jsonrequest or whatever name you like. For now please make your request in one line only. (This app doesn't support pretty print JSON format)

then run it like this.

cat requests.jsonrequest | grpcdiff localhost:50051 yourservice.com:50051 proto.ServiceApp Func

If it detect some differences it will print the differences And if it not detect some differences it will print the time comparison
