Add support for GRPC Server Reflection Protocol about bloomrpc HOT 12 CLOSED

Cool! I'm convinced with this.
I'll be definitely planning to support Reflection in the editor

from bloomrpc.

@fenos gRPC reflection is absolutely used, especially when actively developing an API. Imagine how much time will be saved if I don't have to re-load a changed proto file into this tool (even though there's an easy reload button) for each little API change we're making. To me this is a must :)

It's the main reason we picked grpcui (which is an extension to grpcurl) and retrofitted the reflection API to all our services. Reason being that we have multiple versions in production and it's a pain to have to figure out what proto they are using

@fenos when using evans, I just restart evans and I know I'll have the latest changes. Polling could be an option, or just a "refresh", or call the reflection service before every API call and comparing MD5 ?

@fenos A simple restart of your grpc UI would suffice, polling would be great but not essential.

Has there been any more thought in supporting reflection since it was last discussed here?

Thanks for your comment,

I think there are very few use cases where the server exposes the Reflection API.
Most of the time the third party provider would always provide the .proto file descriptor to make the integration less a black box.

If you can reverse engineer a GRPC endpoint which exposes the Reflection API, would it be possible to create a .proto file from the reflected metadata and then use it in the bloomrpc client?

@fenos Please have a look at https://github.com/fullstorydev/grpcurl#server-reflection which supports server reflection API.

I am not sure how wide spread the usage of the Reflection API is, I personally expose it. I think it's a good exploration mechanism in either case.

I believe you can reverse engineer a GRPC endpoint which exposes the Reflection API and create a .proto. Unfortunately the tooling I use (grpc_cli) doesn't appear to support creating a .proto. If it did, or there was a tool that does it could be a good stop-gap solution in the interim.

@simplesteph Imagine you are developing an API, you are changing the server which either updates or removes 1 field from the request message, or to any message type / service definition.

How can the editor know about that change if the server doesn't tell that to the client?
Polling maybe? 😄

I think you still have the same problem with reflection or am i missing something?

Hello guys.

I saw the PR was merged and I tested it.

If the connection is not successful all imported protos will disappear. Maybe you should look into it.
