zap

Under development.

Usage

import (
 "github.com/uber-go/zap"
 grpczap "github.com/eltorocorp/go-grpc-request-id-interceptor/zap"
 "golang.org/x/net/context"
)

func main() {
 logger = zap.New(zap.NewJSONEncoder())
 uIntOpt := grpc.UnaryInterceptor(grpczap.UnaryServerInterceptor(logger))
 sIntOpt := grpc.StreamInterceptor(grpczap.StreamServerInterceptor(logger))
 grpc.NewServer(uIntOpt, sIntOpt)
}

Structured logging with context

import (
 "github.com/uber-go/zap"
 "github.com/eltorocorp/go-grpc-request-id-interceptor/zap/zapctx"
 "golang.org/x/net/context"
)

func foo(ctx context.Context) {
 // create new a context with some new zap.Field
 newctx := zapctx.MustNewContextWith(ctx,
  zap.String("user_id", 123456"),
 )

 // call other function with the context
 bar(newctx)
}

func bar(ctx context.Context) {
 // logging with additional context
 logger := zapctx.MustFromContext(ctx)
 logger.Info("message",
  zap.String("function", "bar"),
 )
}
