This package provides gRPC Go Middlewares: interceptors, helpers and utilities - 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, tracing, metrics, validation, retries, rate limiting and more, which can be a great generic building blocks that make it easy to build multiple microservices easily.
