    gRPC Go Middleware: interceptors, helpers, utilities.

    Middleware

    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, here's an example:

    import "github.com/grpc-ecosystem/go-grpc-middleware"
    
    myServer := grpc.NewServer(
        grpc.StreamInterceptor(grpc_middleware.ChainStreamServer(
            grpc_ctxtags.StreamServerInterceptor(),
            grpc_opentracing.StreamServerInterceptor(),
            grpc_prometheus.StreamServerInterceptor,
            grpc_zap.StreamServerInterceptor(zapLogger),
            grpc_auth.StreamServerInterceptor(myAuthFunction),
            grpc_recovery.StreamServerInterceptor(),
        )),
        grpc.UnaryInterceptor(grpc_middleware.ChainUnaryServer(
            grpc_ctxtags.UnaryServerInterceptor(),
            grpc_opentracing.UnaryServerInterceptor(),
            grpc_prometheus.UnaryServerInterceptor,
            grpc_zap.UnaryServerInterceptor(zapLogger),
            grpc_auth.UnaryServerInterceptor(myAuthFunction),
            grpc_recovery.UnaryServerInterceptor(),
        )),
    )

    Interceptors

    Please send a PR to add new interceptors or middleware to this list

    Auth

    • grpc_auth - a customizable (via AuthFunc) piece of auth middleware

    Logging

    • grpc_ctxtags - a library that adds a Tag map to context, with data populated from request body
    • grpc_zap - integration of zap logging library into gRPC handlers.
    • grpc_logrus - integration of logrus logging library into gRPC handlers.
    • grpc_kit - integration of go-kit logging library into gRPC handlers.

    Monitoring

    Client

    • grpc_retry - a generic gRPC response code retry mechanism, client-side middleware

    Server

    Status

    This code has been running in production since May 2016 as the basis of the gRPC micro services stack at Improbable.

    Additional tooling will be added, and contributions are welcome.
