clay
Minimal server platform for gRPC and REST+Swagger APIs
Using clay you can automatically spin up HTTP handlers for your gRPC server with complete Swagger defs with a few lines of code.
Why?
There's an excellent grpc-gateway proxy generator,
but it requires you to spin up (at least) one proxy instance in addition to your services.
clay allows you to serve HTTP traffic by server instances themselves for easier debugging/testing.
How?
Check out an example server for a quick start, or dive into step-by-step docs for a full guide.
Flexibility
clay.Server is easily extendable, as you can pass any options gRPC server can use,
but if it's not extendable enough then you can use the .GetDescription() method
of your implementation to register the service in your own custom server
(see ServiceDesc).
