  Let's try to create closer to real world gRPC microservice with tracing and monitoring 👋: Source code u can find here Core tools used what will be used: 🚀 PostgreSQL as database Redis for sessions and caching Jaeger open source, end-to-end distributed tracing Prometheus monitoring and alerting Grafana for to compose observability dashboards with everything from Prometheus

• validator

  71 16,668 7.2 Go

  :100:Go Struct and Field validation, including Cross Field, Cross Struct, Map, Slice and Array diving

  

  Then we usually have to validate request input, for errors gRPC has packages status and codes I found good practice to parse and log errors in handler layer, here i use ParseGRPCErrStatusCode method, which parse err and returns matched gRPC code. Validator is good solution for validation.

• gomock

  41 9,010 2.5 Go

  Discontinued GoMock is a mocking framework for the Go programming language. (by golang)

  

  Every app must be covered by tests, I didn't completely cover all code this one, but wrote some test of course. For testing and mocking testify and gomock is very good tools.

• redigo

  Go client for Redis

  

  Setup postgres and redis Usually production SQL db standard solution for these days is combination of sqlx and pgx. Good Redis Go clients is go-redis and redigo, i used first.

• go-grpc-middleware

  7 6,273 7.2 Go

  Golang gRPC Middlewares: interceptor chaining, auth, logging, retries and more.

  

  I found this is very good gRPC Middleware repository, but we easy can create our own, for example logger interceptor:

• evans

  Evans: more expressive universal gRPC client

  I like to use evans for simple testing gRPC.

• viper

  76 26,967 9.2 Go

  Go configuration with fangs

  In cmd folder let's init all dependencies and start the app. Viper is very good and common choice as complete configuration solution for Go applications. We use here config-local.yml file approach.

• zap

  53 21,822 7.7 Go

  Blazing fast, structured, leveled logging in Go.

  

  Next let's create logger, here i used Uber's Zap under the hood, important here is to create Logger interface for be able to replace logger in the future if it's need.
