simplelog

simplelog is an opinionated logging package designed to facilitate easy and structured logging in Go applications with an absolute minimum of boilerplate.

The idea is that you can add a single import line which replaces the stdlib log/slog default handler, and solve the 90% case for logging.

Features

• if output is a tty, outputs pretty color logs
• if output is not a tty, outputs json
• supports delivering logs via tcp RELP (e.g. to remote rsyslog using imrelp)
• supports delivering each log message via a webhook

Installation

To use simplelog, first ensure your project is set up with Go modules:

go mod init your_project_name

Then, add SimpleLog to your project:

go get git.eeqj.de/sneak/go-simplelog

Usage

Below is an example of how to use SimpleLog in a Go application. This example is provided in the form of a main.go file, which demonstrates logging at various levels using structured logging syntax.

package main

import (
	"log/slog"
	_ "git.eeqj.de/sneak/go-simplelog"
)

func main() {

    // log structured data with slog as usual:
	slog.Info("User login attempt", slog.String("user", "JohnDoe"), slog.Int("attempt", 3))
	slog.Warn("Configuration mismatch", slog.String("expected", "config.json"), slog.String("found", "config.dev.json"))
	slog.Error("Failed to save data", slog.String("reason", "permission denied"))
}
