golang-github-grpc-ecosystem-go-grpc-middleware-dev - 2.1.0-2 main

gRPC Go recently acquired support for Interceptors, i.e. middleware
that is executed either on the gRPC Server before the request is passed
onto the user's application logic, or on the gRPC client either around
the user call. It is a perfect way to implement common patterns: auth,
logging, message, validation, retries or monitoring.
.
These are generic building blocks that make it easy to build multiple
microservices easily. The purpose of this repository is to act as a
go-to point for such reusable functionality. It contains some of them
itself, but also will link to useful external repos.
.
grpc_middleware itself provides support for chaining interceptors.
