Top 23 Go Logging Projects

  • logrus

    Structured, pluggable logging for Go.

    • Project mention: Authentication system using Golang and Sveltekit - Initialization and setup | dev.to | 2023-06-02

    It's some sort of logging system well explained by Alex Edwards in Let’s Go Further. As stated, we could have used logrus or any other popular logging system in Go.

  • loki

    Like Prometheus, but for logs.

    • Project mention: Loki 3.0 Released | news.ycombinator.com | 2024-04-08

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • zap

    Blazing fast, structured, leveled logging in Go.

    • Project mention: Desvendando o package fmt do Go | dev.to | 2023-11-01

  • gf

    GoFrame is a modular, powerful, high-performance and enterprise-class application development framework of Golang. (by gogf)

  • zerolog

    Zero Allocation JSON Logger

    • Project mention: Go 1.21 Released | news.ycombinator.com | 2023-08-08

    Be aware that there is a performance impact compared to using zerolog directly [0] (my uneducated guess is it is likely due to pointer indirection).

  • go-grpc-middleware

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

    • Project mention: Seeking advice on implementing a tinyurl-like service using Go and gRPC. | /r/golang | 2023-05-24

    Hello, Those interviews are even crazy for internship. Anyway 1. Try to find a simple CRUD example online. You can check [this](https://tutorialedge.net/golang/go-grpc-beginners-tutorial/) 2. For logging you can check [go-grpc-middleware](https://github.com/grpc-ecosystem/go-grpc-middleware) 3. You can grpc-gateway in case they want some REST endpoints too 4. Use base62 to encode your url. So at least 2 columns in your table **shortenedUrl** and **url** 5. For such a project no need to use an ORM ( it's not advised anyway ). Implement 2 functions, one to insert into the db and the other one to read from the db. Remember to use transaction though 5. For unit tests go with the standard library and mock the 2 functions ( erroneous and valid cases )
